ASTL/SAS1B 蛋白, Mouse (His)

目录号: HY-P77566
产品使用指南

ASTL/SAS1B 蛋白是一种卵母细胞特异性受体,在精卵粘附中发挥关键作用,而精卵粘附对于受精至关重要。它可以抑制多精症,防止多个精子使一个卵子受精。ASTL/SAS1B 蛋白, Mouse (His) 是重组的 ASTL/SAS1B 蛋白,由 E. coli 表达,带有 N-His 标签。

描述

The ASTL/SAS1B protein is an oocyte-specific receptor that plays a key role in sperm-egg adhesion, which is essential for fertilization. It inhibits polyspermia, preventing multiple sperm from fertilizing one egg. ASTL/SAS1B Protein, Mouse (His) is the recombinant mouse-derived ASTL/SAS1B protein, expressed by E. coli , with N-His labeled tag.

研究背景

ASTL/SAS1B 蛋白作为卵母细胞特异性卵膜受体,对精子和卵子的粘附至关重要,在受精过程中发挥着关键作用。这种蛋白质在抑制多精受精方面具有重要意义,表明它参与阻止多个精子使单个卵子受精。ASTL/SAS1B 可能充当蛋白酶,负责 ZP2(透明带的一个组成部分)的受精后裂解。ZP2 的裂解发生在受精和皮质颗粒胞吐作用后的透明带表面。这种酶活性使得透明带无法支持进一步的精子结合,从而有助于受精过程的调节。

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

浓度 (start) × 体积 (start) = 浓度 (final) × 体积 (final)
× = ×

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
