描述

The CTLA-4 protein is a key inhibitory receptor and a major negative regulator of T cell responses in coordination of immune regulation. Its unique property is its significantly increased affinity for B7 ligands (CD80/CD86) compared with CD28. CTLA-4 Protein, Human (Biotinylated, HEK293, His-Avi) is the recombinant human-derived CTLA-4 protein, expressed by HEK293 , with C-Avi, C-His labeled tag. The total length of CTLA-4 Protein, Human (Biotinylated, HEK293, His-Avi) is 126 a.a., with molecular weight of 25-30 kDa.

研究背景

GMP CTLA-4 是一种关键的抑制性受体,是在免疫调节的复杂框架内协调 T 细胞反应的主要负调节因子。这种调节功能源于 GMP CTLA-4 的独特特性,与同源刺激辅助受体 CD28 相比,其对其天然 B7 家族配体 CD80 和 CD86 的亲和力显着增强。这种结合亲和力的显着差异使 GMP CTLA-4 能够与 CD80/B7-1 和 CD86/B7.2 竞争性结合,对 T 细胞激活产生抑制影响并微调免疫反应。GMP CTLA-4 的同二聚体结构通过二硫键错综复杂地连接,进一步强调了其在免疫调节中作为分子哨兵的作用。此外,GMP CTLA-4 与 ICOSLG 相互作用,有助于其在免疫检查点通路中的多方面参与。

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
