DESCRIPTION  描述

Additive Screen is a library of reagents that can affect the solubility and crystallization of biological macromolecules, including both soluble and membrane proteins.

These reagents can perturb and manipulate sample-sample and sample-solvent interactions, as well as perturb water structure which can alter and improve both the solubility and crystallization of a sample. Additives can stabilize or engender conformity by specific interaction with the macromolecules. There are numerous reports of the use of additives to improve the quality and size of macromolecular crystals.1-5

Additive screen reagent classifications include multivalent, salt, amino acid, dissociating agent, linker, polyamine, osmolyte, chaotrope, co-factor, reducing agent, chelating agent, polymer, carbohydrate, non-detergent, amphiphile, detergent, non-volatile organic and volatile organic.

Additive Screen contains 96 unique reagents, 1 ml each.

Additive Screen HT contains 96 unique reagents, 1 ml each, in a single Deep Well block.

Additive Screen 是一个试剂库，可以影响生物大分子的溶解度和结晶，包括可溶性蛋白和膜蛋白。

这些试剂可以干扰和操纵样品-样品和样品-溶剂的相互作用，以及可以改变和改善样品溶解度和结晶的水结构。添加剂可以通过与大分子的特定相互作用来稳定或产生一致性。有许多关于使用添加剂来改善大分子晶体的质量和尺寸的报道。 1-5

添加剂筛选试剂分类包括多价、盐、氨基酸、解离剂、连接剂、多胺、渗透剂、离液剂、辅助因子、还原剂、螯合剂、聚合物、碳水化合物、非去污剂、两亲物、去污剂、非挥发性有机物和挥发性有机物。

Tacsimate pH 4, 5, 6, 7, 8, & 9

APPLICATIONS

  • Crystallization grade Tacsimate for formulating screens or for optimization

FEATURES

  •  Sterile filtered solution
  • Formulated in Type 1+ ultrapure water: 18.2 megaohm-cm resistivity at 25°C, < 5 ppb Total Organic Carbon, bacteria free (<1 Bacteria (CFU/ml)), pyrogen free (<0.03 Endotoxin (EU/ml)), RNase-free (< 0.01 ng/mL) and DNase-free (< 4 pg/µL)

DESCRIPTION

To screen pH as a crystallization variable using Tacsimate one can mix together different ratios of different pH Tacsimate solutions. Refer to the pdf “Mixing Tacsimate Stocks to Screen pH” on this page. Or, one can add a buffer to the crystallizaiton reagent containing Tacsimate. Recommended final buffer concentration in the reagent well is 0.05 to 0.1 M.

ClearSeal Film Before and After

Description
ClearSeal Film fits all SBS format 96 well plates. Minimal evaporation, minimal cross-well contamination, easy to handle, and optically clear. Single coated, 2 mil (0.05 mm), optically clear polyolefin film with pressure-sensitive silicone-based adhesive. Supplied as a 141 mm x 78 mm film with white polyester release liner (backing). Actual seal area after end tabs removed is 120 x 78 mm Seals well to polypropylene, polystyrene, and polycarbonate plates. Compatible with aqueous and organic solvents. Suitable for use between -70 and 110°C. For best seal, the plate must be sealed with the Film Sealing Paddle HR4-513. ClearSeal Film has a limited shelf life. Must be used before expiration date printed on box. Each pack of film (HR4-521) includes one free Film Sealing Paddle (available separately as HR4-413).

HR4-413 Film Sealing Paddle, 3 7/8″ x 2 15/16″, polyethylene, white. 5 paddles per pack. An alternative to the plate roller or brayer for pressing films to assure a secure uniform seal around all wells on 96-well, 384-well, and 1536-well plates. These paddles are especially recommended for sealing films on raised-rim plates because they fit within the rim of the plate.
