描述

CD28 Protein, a crucial regulator of T-cell activation, promotes cell proliferation, cytokine production, and T-cell survival. It enhances IL4 and IL10 production when combined with TCR/CD3 ligation and CD40L costimulation. CD28 Protein exists as a disulfide-linked homodimer and interacts with DUSP14, CD80/B7-1, CD86/B7-2/B70, and GRB2 (By similarity). CD28 Protein, Mouse (Biotinylated, HEK293, His) is the recombinant mouse-derived CD28 protein, expressed by HEK293 , with C-His labeled tag. The total length of CD28 Protein, Mouse (Biotinylated, HEK293, His) is 130 a.a., with molecular weight of 32-35 kDa.
研究背景

CD28 蛋白是 T 细胞激活的关键参与者，参与诱导细胞增殖、细胞因子产生和促进 T 细胞存活。与 TCR/CD3 连接和 CD40L 共刺激相结合时，它可增强 T 细胞中 IL4 和 IL10 的产生。CD28 蛋白通过二硫键以同二聚体形式存在，并与 DUSP14 相互作用。它与 CD80/B7-1 和 CD86/B7-2/B70 结合，并且还与 GRB2 相互作用（通过相似性）。

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
