描述

The CD28 protein is critical for T cell activation, enhancing proliferation, cytokine production, and survival. When linked to TCR/CD3 and CD40L, CD28 promotes the production of IL4 and IL10, thereby regulating immune responses. CD28 Protein, Human/Cynomolgus/Rhesus Macaque (HEK293, mFc) is the recombinant cynomolgus-derived CD28 protein, expressed by HEK293 , with N-mFc labeled tag.

研究背景

CD28 蛋白在 T 细胞激活、促进细胞增殖、细胞因子产生和 T 细胞存活中发挥着关键作用。与 TCR/CD3 和 CD40L 共刺激连接后,CD28 增强 T 细胞中 IL4 和 IL10 的产生,有助于免疫反应调节。此外,CD28 的异构体 3 促进 T 细胞中 CD40L 介导的 NF-κ-B 以及激酶 MAPK8 和 PAK2 的激活。该蛋白通过二硫键形成同型二聚体,并与多种分子相互作用,包括 DUSP14、CD80/B7-1、CD86/B7-2/B70 和 GRB2。同工型 3 与 CD40LG 特异性相互作用,突出了其在介导免疫反应和细胞信号传导途径中的多方面作用。

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
