描述

The NDSB are a group of zwitterionic compounds that can reduce aggregation and aid in refolding proteins found in inclusion bodies and bacterial expression systems.

Non detergent sulfobetaines have a sulfobetaine hydrophilic group and a short hydrophobic group that cannot aggregate to form micelles, therefore NDSB’s are not considered detergents. NDSB increase the extraction yield (up to 30%) of membrane, nuclear and cyto-skeletal associated proteins. The short hydrophobic groups combined with the charge neutralization of the sulfobetaine group results in higher yields of membrane proteins. NDSB have been used in refolding and renaturation of chemically and thermally denatured proteins.

Typical useful NDSB concentration in protein sample is 0.5-1.0 M.

NDSB 是一组两性离子化合物,可以减少聚集并帮助重新折叠包涵体和细菌表达系统中发现的蛋白质。

非洗涤剂磺基甜菜碱有一个磺基甜菜碱亲水基团和一个不能聚集形成胶束的短疏水基团,因此 NDSB 不被视为洗涤剂。 NDSB 可提高膜、核和细胞骨架相关蛋白的提取率(高达 30%)。 短疏水基团与磺基甜菜碱基团的电荷中和相结合,导致膜蛋白产量更高。 NDSB 已用于化学和热变性蛋白质的重折叠和复性。

描述

The NDSB are a group of zwitterionic compounds that can reduce aggregation and aid in refolding proteins found in inclusion bodies and bacterial expression systems.

Non detergent sulfobetaines have a sulfobetaine hydrophilic group and a short hydrophobic group that cannot aggregate to form micelles, therefore NDSB’s are not considered detergents. NDSB increase the extraction yield (up to 30%) of membrane, nuclear and cyto-skeletal associated proteins. The short hydrophobic groups combined with the charge neutralization of the sulfobetaine group results in higher yields of membrane proteins. NDSB have been used in refolding and renaturation of chemically and thermally denatured proteins.

NDSB 是一组两性离子化合物,可以减少聚集并帮助重新折叠包含体和细菌表达系统中发现的蛋白质。

非洗涤剂磺基甜菜碱有一个磺基甜菜碱亲水基团和一个不能聚集形成胶束的短疏水基团,因此 NDSB 不被视为洗涤剂。 NDSB 可提高膜、核和细胞骨架相关蛋白的提取率(高达 30%)。 短疏水基团与磺基甜菜碱基团的电荷中和相结合,导致膜蛋白产量更高。 NDSB 已用于化学和热变性蛋白质的重折叠和复性。

Typical useful NDSB concentration in protein sample is 0.5-1.0 M.

描述

18 mm Mounted CryoLoops with 20 micron diameter nylon. Nylon loops are staked to hollow, stainless steel MicroTubes™ that are used to mount, freeze, and secure the crystal during cryocrystallographic procedures and X-ray data collection. The MicroTube on the 18 mm Mounted CryoLoops is 18 mm in length and ready to insert into CrystalCap Magnetic and CrystalCap HT. The 20 micron diameter nylon loops show minimal diffraction, are thin for fast cryo cooling of the crystal, strong, and aerodynamic.

For use with CrystalCap, CrystalCap ALS, CrystalCap ALS HT and CrystalCap SPINE HT systems. Not compatible with the CrystalCap Copper, CrystalCap Copper HT, or CrystalCap ALS HT.

Mounted CryoLoop™ – 20 micron

应用

  • Cryocrystallography
  • 低温晶体学

特征

  • Synthetic CryoLoop on stainless steel MicroTube
  • MicroTube specially engineered with EasySnap notches
  • Complete range of loop diameters from 0.025 – 1.0 mm
  • Compatible with all CrystalCap Systems

    与所有 CrystalCap 系统兼容

描述

Note: If you are using the CrystalCap, CrystalCap ALS, CrystalCap ALS HT, or CrystalCap SPINE HT, save time and money by using the ready to mount 18 mm Mounted CryoLoop.

Mounted CryoLoops with 20 micron diameter nylon. These nylon loops are bonded to hollow, stainless steel MicroTubes™ that are used to mount, freeze, and secure the crystal during cryocrystallographic procedures and X-ray data collection. The MicroTube is 24 mm in length and is specially engineered with EasySnap™ notches at the 10, 12, 14, 18, and 21 mm measures. To obtain the desired length of MicroTube, simply snap the MicroTube at the desired length and secure to the CrystalCap using epoxy or similar adhesive. These nylon loops show minimal diffraction, are thin for fast freezing, strong, and aerodynamic..

Most data collection geometries prefer or require a 22 mm length between the base of the cap and the beam. For a 22 mm overall length using the CrystalCap, CrystalCap ALS, CrystalCap ALS HT and CrystalCap SPINE HT, snap the MicroTube at the second notch from the bottom, creating an 18 mm MicroTube lenghth and secure to the CrystalCap using epoxy or similar adhesive. For a 22 mm over length using the CrystalCap Copper, CrystalCap Copper HT, CrystalCap ALS Copper HT snap the MicroTube at the fifth notch from the bottom (notch closest to the CryoLoop) and secure to the CrystalCap using epoxy or similar adhesive.

注意:如果您使用的是 CrystalCap、CrystalCap ALS、CrystalCap ALS HT 或 CrystalCap SPINE HT,请使用可安装的 18 毫米已安装 CryoLoop 来节省时间和金钱。

安装有 20 微米直径尼龙的 CryoLoops。这些尼龙环与中空不锈钢 MicroTubes™ 粘合,用于在低温晶体学程序和 X 射线数据收集过程中安装、冷冻和固定晶体。 MicroTube 的长度为 24 毫米,专门设计了 10、12、14、18 和 21 毫米尺寸的 EasySnap™ 凹槽。要获得所需长度的 MicroTube,只需将 MicroTube 卡入所需长度并使用环氧树脂或类似粘合剂固定到 CrystalCap。这些尼龙环显示出最小的衍射,很薄,可以快速冷冻,坚固且符合空气动力学。

大多数数据收集几何结构更喜欢或要求帽底和梁之间有 22 毫米的长度。对于使用 CrystalCap、CrystalCap ALS、CrystalCap ALS HT 和 CrystalCap SPINE HT 的 22 mm 总长度,将 MicroTube 从底部的第二个凹口处卡入,形成 18 mm 的 MicroTube 长度并使用环氧树脂或类似粘合剂固定到 CrystalCap。对于 22 mm 以上的长度,使用 CrystalCap Copper、CrystalCap Copper HT、CrystalCap ALS Copper HT 将 MicroTube 卡在从底部算起的第五个槽口(最靠近 CryoLoop 的槽口),并使用环氧树脂或类似粘合剂固定到 CrystalCap。
