JBScreen Plus is an additive screen for optimization of preliminary crystallization conditions. The selection of the additives is based upon the Hofmeister series, which orders ions based upon their ability to stabilize protein structure. Ions can be classified as either kosmotropic or chaotropic. The first have structure stabilizing properties, and may assist in, e.g. crystallizing proteins with a large proportion of flexible loop regions. The latter have structure disturbing properties, and may assist in the crystallization of large complexes, allowing them to re-arrange to form favorable crystal contacts.

JBScreen Plus consists of 5 individual kits, JBScreen Plus Kosmotropic, JBScreen PlusChaotropic, JBScreen Plus Salts, JBScreen Plus Additives and JBScreen Plus Volatiles, containing 24 different additives each. The ready-to-use reagents are supplied in 1 ml aliquots.

The 96 solutions of JBScreen Plus HTS, comprising the reagents of the kosmotropic, chaotropic, salts and additive kits, are supplied in a sterile deep well block containing either 200 µl (JBScreen Plus HTS S) or 1 ml (JBScreen Plus HTS L).

JBScreen Plus HTS S is particularly designed for low volume users. The screening reagents can be added directly to the additives in the deep well block before starting a vapor diffusion experiment, while JBScreen Plus HTS L will enable you to transfer any desired volume of additive solution to your plate.

产品信息
产品描述
产品规格
JBScreen Plus 是一种用于优化初步结晶条件的添加剂筛。添加剂的选择基于 Hofmeister 系列，它根据离子稳定蛋白质结构的能力对它们进行排序。离子可分为亲液性或离液性。第一个具有结构稳定特性，并且可能有助于，例如结晶具有大部分柔性环区域的蛋白质。后者具有结构干扰特性，可能有助于大配合物的结晶，使它们重新排列以形成有利的晶体接触。

JBScreen Plus 由 5 个独立的套件组成，JBScreen Plus Kosmotropic、JBScreen PlusChaotropic、JBScreen Plus Salts、JBScreen Plus Additives 和 JBScreen Plus Volatiles，每个套件包含 24 种不同的添加剂。即用型试剂以 1 ml 等分试样提供。

JBScreen Plus HTS 的 96 种溶液，包括亲液、离液、盐和添加剂试剂盒的试剂，以无菌深孔块形式提供，含有 200 µl (JBScreen Plus HTS S) 或 1 ml (JBScreen Plus HTS L)。

JBScreen Plus HTS S 专为低音量用户设计。在开始蒸汽扩散实验之前，筛选试剂可以直接添加到深孔模块中的添加剂中，而 JBScreen Plus HTS L 将使您能够将任何所需体积的添加剂溶液转移到您的板上。
