NAME

Perfluoropolyether Cryo Oil

DESCRIPTION

PRICE

应用

  • Oil based cryoprotectant
  • 油基防冻剂

特征

  • Perfluoropolyether cryo oil
  • Low viscosity
  • Low surface tension
  • Cryoprotectant for soluble and membrane protein crystals
  • 全氟聚醚冷冻油
    低粘度
    低表面张力
    可溶性和膜蛋白晶体的冷冻保护剂

描述

Used during cryocrystallography to displace and reduce the amount of water (mother liquor, reagent) on the crystal after the crystal is mounted in a cryoloop. Coating the crystal with oil can minimize evaporation from the crystal and reduce exposure and slow diffusion of air (oxygen) to the crystal.

Perfluoropolyether Cryo Oil offers low viscosity, extremely low vapor pressure, low surface tension, excellent chemical inertness and excellent thermal stability.

Dip the mounted crystal into the oil to displace surface water. Or add a small amount of Perfluoropolyether to the crystallization drop before mounting the crystal. After adding the Perfluoropolyether, mount the crystal using a Mounted Cryoloop. Withdraw the mounted crystal from the drop and the Perfluoropolyether will coat the mounted crystal. Cryogenically cool the mounted crystal.

在晶体安装在低温回路中后,在低温晶体学期间用于置换和减少晶体上的水(母液、试剂)量。 用油涂抹晶体可以最大限度地减少晶体的蒸发并减少空气(氧气)向晶体的暴露和缓慢扩散。

全氟聚醚冷冻油具有低粘度、极低蒸气压、低表面张力、优异的化学惰性和优异的热稳定性。

将安装的晶体浸入油中以置换表面水。 或者在安装晶体之前在结晶液滴中加入少量的全氟聚醚。 添加全氟聚醚后,使用 Mounted Cryoloop 安装晶体。 从液滴中取出已镶嵌的晶体,全氟聚醚将覆盖已镶嵌的晶体。 低温冷却安装的晶体。

NAME

Santovac Cryo Oil

DESCRIPTION

PRICE

应用

  • Oil based cryoprotectant
  • 油基防冻剂

特征

  • Low viscosity
  • Low surface tension
  • Cryoprotectant for soluble and membrane protein crystals
  • Not miscible with most solvents
  • Non toxic, non penetrating cryoprotectant
  • 低粘度
    低表面张力
    可溶性和膜蛋白晶体的冷冻保护剂
    不与大多数溶剂混溶
    无毒、非渗透性冷冻保护剂

描述

Used during cryocrystallography to displace and reduce the amount of water (mother liquor, reagent) on the crystal after the crystal is mounted in a cryoloop. Coating the crystal with oil can minimize evaporation from the crystal and reduce exposure and slow diffusion of air (oxygen) to the crystal.

Santovac Cryo Oil offers low viscosity, incredibly low vapor pressure, low surface tension, excellent chemical inertness and excellent thermal stability.

Dip the mounted crystal into the oil to displace surface water. Or add a small amount of Santovac to the crystallization drop before mounting the crystal. After adding the Santovac, mount the crystal using a Mounted Cryoloop. Withdraw the mounted crystal from the drop and the Santovac will coat the mounted crystal. Cryogenically cool the mounted crystal.

Santovac (Santovac 5) is a five ring polyphenyl ether (PPE) with very low vapor pressure and low reactivity. The oil is highly resistant to oxidation. The only elements in the pure polyphenyl ether are oxygen, hydrogen and carbon.

The fluid is chemically stable, non-corrosive, safe and non-toxic at normal operating temperatures.

Santovac is not miscible with water, paraffin oil, silicon oil, alkanes, or Parabar 10312 (Paratone). Santovac is miscible with acetone. Shelf life 5 years.

Santovac® is a trademark of Santovac® Fluids.

在晶体安装在低温回路中后,在低温晶体学期间用于置换和减少晶体上的水(母液、试剂)量。用油涂抹晶体可以最大限度地减少晶体的蒸发并减少空气(氧气)向晶体的暴露和缓慢扩散。

Santovac Cryo Oil 具有低粘度、极低的蒸气压、低表面张力、出色的化学惰性和出色的热稳定性。

将安装的晶体浸入油中以置换表面水。或者在安装晶体之前将少量的 Santovac 添加到结晶液滴中。添加 Santovac 后,使用 Mounted Cryoloop 安装晶体。从水滴中取出已镶嵌的水晶,Santovac 将覆盖已镶嵌的水晶。低温冷却安装的晶体。

Santovac (Santovac 5) 是一种五环聚苯醚 (PPE),具有极低的蒸气压和低反应性。该油具有很强的抗氧化性。纯聚苯醚中唯一的元素是氧、氢和碳。

该流体在正常工作温度下化学性质稳定、无腐蚀性、安全无毒。

Santovac 与水、石蜡油、硅油、烷烃或 Parabar 10312 (Paratone) 不混溶。 Santovac 可与丙酮混溶。保质期5年。

Santovac® 是 Santovac® Fluids 的商标。

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.

The non detergent sulfobetaines are zwitterionic over a wide pH range, easily removed by dialysis and do not absorb significantly in the near UV range.

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。

非去污剂磺基甜菜碱在很宽的 pH 值范围内是两性离子的,很容易通过透析去除,并且在近紫外范围内不会显着吸收。

蛋白质样品中典型的有用 NDSB 浓度为 0.5-1.0 M。
