描述

IGFBP‐2 is a member of a family of six insulin‐like growth factor (IGF) binding proteins. IGFBP-2 is the second most abundant IGFBP in the circulation and binds IGF-II with higher affinity than IGF-I. IGFBP-2 has been implicated in the regulation of IGF activity in most tissues and organs. IGFBP-2 Protein, Rhesus Macaque (HEK293, His) is the recombinant Rhesus Macaque-derived IGFBP-2 protein, expressed by HEK293 , with C-His labeled tag.

研究背景

IGFBP‐2 是胰岛素样生长因子 (IGF) 结合蛋白家族的成员。IGFBP-2 是循环中第二丰富的 IGFBP,与 IGF-II 的结合比 IGF-I 具有更高的亲和力。IGFBP-2 与大多数组织和器官中IGF 活性的调节有关。IGFBP‐2 参与胰岛素样生长因子受体信号通路的调节[1][2][3][4]

生物活性

Measured by its ability to inhibit the biological activity of IGF-I on MCF-7 human breast cancer cells. The ED50 for this effect is 0.03282 µg/mL in the presence of 14 ng/mL rh IGF-I, corresponding to a specific activity is 3.047×104 units/mg.

复溶方法

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH2O.

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.

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
