Dialysis Buttons蛋白结晶试剂盒Hampton Research
Hampton Research蛋白结晶试剂盒
Products > Crystallization Plates, Hardware & Accessories > Dialysis Buttons, Membranes & Applicators > Dialysis Buttons
Dialysis Buttons
Applications
- Crystallization by dialysis, protein folding, & small volume sample dialysis
Features
- Low volume dialysis
- Fits in 24 well plates
- Use over and over again
Description
In the dialysis method, the sample in question is separated from the “precipitant” by a semi-permeable membrane which allows small reagent molecules to pass but prevents biological macromolecules from crossing the membrane.1-3
Dialysis Buttons are injection molded from polystyrene, and are the size of a small button. The sample is placed in this chamber so as to create a slight dome of liquid at the top of the button. A dialysis membrane is placed over the top of the button/sample and is held in place with an O-ring. The O-ring is held in place by a groove in the Dialysis Button. Dialysis Buttons are supplied with O-rings. The 5 µl to 100 µl sized dialysis buttons have an approximate overall height of 6 mm, an approximate outside diameter of 10 mm without an O-ring in place, and an approximate diameter of 12 mm with an O-ring in place. The 200 µl and 350 µl sized dialysis buttons have an approximate overall height of 8 mm, an approximate outside diameter of 15 mm without an O-ring in place, and an approximate diameter of 17 mm with an O-ring in place. Each package of dialysis buttons includes a plastic golf tee shaped applicator to assist with applying a dialysis membrane to the button and securing with the supplied o-ring.

PEG/pH • PEG/pH 2 • PEG/pH HT蛋白结晶试剂盒Hampton Research
Hampton Research蛋白结晶试剂盒
Products > Crystallization Screens > PEG/pH • PEG/pH 2 > PEG/pH • PEG/pH 2 • PEG/pH HT
PEG/pH • PEG/pH 2 • PEG/pH HT
Applications
- Crystallization screen where Polyethylene glycol 4,000 and buffers sample an acidic to neutral, and/or neutral to alkaline pH
Features
- Developed at Hampton Research
- PEG/pH samples pH 3.5 – 7.4 in 0.2 M buffer
- PEG/pH 2 samples pH 6.4 – 9.6 in 0.2 M buffer
- PEG/pH HT samples pH 3.5 – 9.6 in 0.2 M buffer
- Polyethylene glycol 4,000 – primary reagent
- PEG/pH & PEG/pH 2 each utilize 10 unique buffers, 0.2 M – secondary reagent
- PEG/pH HT 20 unique buffers, 0.2 M – secondary reagent
- Compatible with vapor diffusion, microbatch, free interface diffusion
Description
pH is an effective solubility, stability and crystallization variable because most proteins demonstrate pH dependent solubility minima and will solubilize, precipitate, or crystallize at particular pH values or in the presence of specific buffers. The solubility minima may correspond with the isoelectric point (pI) of the protein, but this is not always the case. The solubility minima and maxima is often complex and may depend on other chemical and physical variables in the crystallization experiment.
Using PEG/pH, PEG/pH 2, or PEG/pH HT one isolates pH, buffer type and relative supersaturation from other chemical and physical variables to screen the effect that pH and buffer type have on the solubility, stability, homogeneity, monodispersity and crystallization of the sample. Varying the pH can alter the protonation state and charge of amino acid residues in the protein, generating different species of the protein for solubility and crystallization screening. The change in pH can have a dramatic effect on inter and intramolecular contacts in the protein and can manipulate how the protein interacts with itself, the surrounding solvent and chemicals in the drop. By screening buffer type and pH in a low ionic strength environment of Polyethylene glycol, PEG/pH simultaneously delivers as a solubility and a crystallization screen for proteins.
Designed as a 96 reagent screen, but offered as two sets of 48 x 10 ml reagents or a single 96 x 1 ml reagent block, PEG/pH, PEG/pH 2, and PEG/pH HT samples Polyethylene glycol 4,000 versus 20 different buffers, at 0.2 M, while sampling pH 3.5 – 9.6.
PEG/pH 1 samples 20% w/v Polyethylene glycol 4,000 versus pH 3.5 – 7.4 in 0.2 M buffer. PEG/pH is supplied in a 48 x 10 ml tube format. PEG/pH is compatible with vapor diffusion, free interface diffusion, and microbatch crystallization methods. For research use only.
PEG/pH 2 samples 20% w/v Polyethylene glycol 4,000 versus pH 6.4 – 9.6 in 0.2 M buffer. PEG/pH 2 is supplied in a 48 x 10 ml tube format. PEG/pH 2 is compatible with vapor diffusion, free interface diffusion, and microbatch crystallization methods. For research use only.

Rodent diets
As a researcher, you want to have as much control as possible over what goes into your study animals. At Envigo, we understand that. That is why we developed Teklad Global Rodent Diets® .
Teklad Global Rodent Diets® are a special integrated range of vegetarian laboratory rodent diets developed to be nutritionally complete for various life stages from breeding through long-term maintenance. Global rodent laboratory diets contain levels of protein, energy, vitamins and minerals that are more appropriate to the needs of modern biomedical research studies.
Furthermore, in global rodent diets particular attention has been placed on avoiding, as far as practical, ingredients that are reported to have adverse confounding effects on experimental results. This has resulted in a range of Teklad rodent laboratory diets that contain:
- No fish meal
- No meat meals or meat by-products
- No alfalfa meal
- No soybean meal or reduced levels
- No animal fat
By excluding animal by-products, the presence of nitrosamines (a potential carcinogen) is avoided. Exclusion of alfalfa meal reduces chlorophyll, improving optical imaging clarity. Reduction or removal of soybean meal, together with elimination of alfalfa meal, minimizes levels of naturally-occurring phytoestrogens. Phytoestrogens interact with endogenous estrogens and potentially can affect studies in many research areas. Read more about this in these pieces:
- Dietary phytoestrogens, a source of research variation
Ask a nutritionist series: Impact of phytoestrogens on research, Volume 1 - Phytoestrogens limit translation of preclinical results to clinical outcomes

Not all products are stocked locally; extended lead time and additional fees may apply.
Many diets are available in certified format designated by a “C” following the product code. When diets are certified a representative sample is tested for a panel of contaminants. If not stocked as certified, certification can be made available upon request. Minimum order size and additional charges may apply.
Traditional rodent diets were formulated decades ago based on understanding of rodent nutrition, ingredients, and diet manufacturing at the time. While traditional diets will supply the known nutrient needs of your laboratory animals, we recommend you consider the use of a diet from our newer global diet line for your modern research needs.
Teklad Global Rodent Diets® are modern formulas designed to reduce research variables. Specifically, these diets contain more appropriate nutrient levels, and limit or exclude ingredients that are reported to have effects on a wide variety of research endpoints.
- Lower, more appropriate protein levels can improve survival and reduce morbidity
- Vegetarian with no nitrosamines (a potential carcinogen)
- Formulated to exclude alfalfa meal, greatly improving fluorescent imaging clarity
- Formulated to exclude or lower soybean meal, thus minimizing the presence of isoflavones, the primary type of phytoestrogen found in lab animal diets
- Extruded rodent diets dramatically reduce clumping and hardness after autoclaving (2018SX , 2019S , 2020SX ), and in general result in less diet waste and cleaner cages
Teklad rodent diets are natural-ingredient diets specifically formulated to provide the proper balance of all known nutrients considered essential for the growth, maintenance, and reproduction of rats, mice, gerbils and hamsters. These diets conform to the nutrient requirements for rodents established by the National Research Council (1995).
Teklad rodent diets provide uniform nutrition. They are fixed-formula diets designed to minimize the nutrient variances which otherwise could occur if the ingredient composition of a diet were altered from one batch to the next.
Protein is supplied primarily by plant sources. Supplemental amino acids are added to provide the proper amount and balance of essential amino acids. All rodent diets are fortified with vitamins and minerals to help support the regulation of body fluids and the proper functioning of body systems to ensure the adequate growth, maintenance, and reproduction of research rodents. Autoclavable diets are supplemented with additional vitamins to compensate for losses that occur during autoclaving. Since our diets are nutritionally complete and balanced, it is not necessary to add dietary supplements.
There is no definitive point where one is able to predict when a specific diet will spoil or become deficient in one or more nutrients. The common guideline of a six month shelf life is based on longstanding practice in North America. In Europe and Asia, differences in local practices and regulatory oversight have led to Teklad standard natural ingredient diets being routinely used out to nine months and sometimes 12 months post-manufacture. This practical experience, along with literature support and vitamin testing over time, gives us confidence that these diets continue to support animal health and study integrity out to at least nine months post-manufacture. Please refer to your institution for guidance if you are unsure of local policies.
Recommended storage conditions:
- Cool and dry; at or below 70 degrees fahrenheit with humidity ideally below 50%, but up to 65% is acceptable
- Clean and free of pests
- In original packaging or in a container that prevents continuous exposure to light and minimal exposure to air
Standard natural ingredient rodent diets are complete diets for rats, mice, gerbils and hamsters, that should be allowed ad libitum access to the diet. Fresh water should be available at all times.

Carbohydrate adjusted
A few carbohydrate adjusted formulas are shown below. Please contact us for additional formulas of this nature or for more information about altering the carbohydrate profile of a diet.
Formula examples:
- TD.89247 60% Fructose diet
- TD.86489 Diet with adjusted sucrose/cornstarch
- TD.96348 Diet (20% lactose, 2% Ca, 1.25% P)
- TD.98090 70% Carbohydrate diet
- TD.96355 Ketogenic diet (almost no carbohydrate)
Carbohydrates often make up the majority (by weight and % kcal) of custom research diets, with the exception of higher fat diets. Commonly used carbohydrate sources include sucrose, cornstarch and maltodextrin. Other sources include fructose, dextrose (glucose), dextrin, and lactose. Maltodextrin is enzymatically derived from cornstarch to have shorter glucose polymers and is helpful in pelleting high fat diets and in diets where cornstarch exceeds sucrose.
Sucrose is a part of most formulas, often making up 10% of the diet or more. This likely adds to the palatability of the diet. The carbohydrate profile of a diet can be manipulated, although some mixtures may not pellet. There are also diets with very little carbohydrate, thus containing high amounts of fat and/or protein.
Cellulose (fiber) is part of many formulas and while not required by rodents, is considered beneficial. It can also be used to make formulas with differing macronutrient profiles isocaloric.

AIN diet formulas
These formulas are purified diets with commonly used refined ingredients. These basic formulas are often modified for a specific research purpose, such as altering the fat source, a vitamin or mineral level, or adding a compound. See the FAQ section to learn more about the history of these formulas, AIN-76A, AIN-93G, and AIN-93M.
These formulas (as well as other purified diets) do not contain alfalfa and can be used to reduce background autofluorescence in certain imaging applications. Our Global Rodent Diets are also alfalfa-free and are suitable for imaging work. Please contact us for further information about these formulas or modifications.
