描述

PSG1 Protein is extremely vital to development and health of a fetus. PSG1 Protein is important in inducing, enhancing or inhibiting an immune response[1][2]. PSG1 Protein, Human (HEK293, His) is the recombinant human-derived PSG1 protein, expressed by HEK293 , with C-6*His labeled tag. The total length of PSG1 Protein, Human (HEK293, His) is 385 a.a., with molecular weight of ~68 kDa.

研究背景

PSG1 蛋白是人类 PSG 家族的一种分泌型糖蛋白[3]。PSG1 蛋白是母体血清中最丰富的 PSG,可能是促血管生成生长因子的诱导剂,已知在母胎界面脉管系统的建立中发挥着重要作用[4]。PSG1 蛋白主要作为免疫调节剂来保护生长中的胎儿[5]

分子量

Approximately 68 kDa

纯度

Greater than 95% as determined by reducing SDS-PAGE.

性状

无菌粉末.

组分

Lyophilized from a 0.2 μm filtered solution of 20 mM PB,150 mM NaCl, pH 7.4.

内毒素含量

<1 EU/μg, determined by LAL method.

复溶方法

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

保存条件 & 期限

Stored at -20°C for 2 years. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

运输条件

Room temperature in continental US; may vary elsewhere.

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)
× = ×
C1   V1   C2   V2

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
