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

Mounted CryoLoops with 10 micron diameter nylon. The 10 micron Mounted CryoLoop shows less background diffraction than the 20 micron Mounted CryoLoop. Please note that the 10 micron Mounted CryoLoops are very flexible due to their small diameter. 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.

安装有 10 微米直径尼龙的 CryoLoops。 10 微米安装的 CryoLoop 显示的背景衍射比 20 微米安装的 CryoLoop 少。请注意，10 微米安装的 CryoLoop 因其小直径而非常灵活。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。

  • Cryocrystallography

描述

Similar to the Mounted CryoLoop™ in design and function, the Adjustable Mounted CryoLoop allows one to manipulate and orient the CryoLoop to multiple, unique positions previously unattainable with typical cryo setups. The Adjustable Mounted CryoLoop is a 20 micron diameter synthetic loop mounted inside a malleable stainless steel sleeve, which in turn, is mounted inside the EasySnap MicroTube™.

Using forceps or a probe one can manipulate the angle and orientation of the CryoLoop by bending and adjusting the angle of the malleable stainless steel insert which holds the CryoLoop. The Adjustable Mounted CryoLoop may be positioned several times. Note: Repeated manipulation will fatigue the sleeve which can lead to failure of the sleeve. The Adjustable Mounted CryoLoop is designed to work with the CrystalCap System components.

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 stake it to the CrystalCap™ Magnetic or CrystalCap™ Copper Magnetic. 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.

在设计和功能上与 Mounted CryoLoop™ 类似，可调节的 Mounted CryoLoop 允许人们操纵 CryoLoop 并将其定位到多个独特的位置，这些位置以前是典型的低温设置无法达到的。可调节安装的 CryoLoop 是一个直径 20 微米的合成环，安装在可延展的不锈钢套管内，而不锈钢套管又安装在 EasySnap MicroTube™ 内。

使用镊子或探针可以通过弯曲和调整固定 CryoLoop 的可延展不锈钢插件的角度来控制 CryoLoop 的角度和方向。可调节安装的 CryoLoop 可以多次定位。注意：重复操作会使套筒疲劳，从而导致套筒失效。可调节安装的 CryoLoop 设计用于与 CrystalCap 系统组件一起使用。

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 卡入所需长度并将其固定在 CrystalCap™ Magnetic 或 CrystalCap™ Copper Magnetic 上。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。
