描述

ICOS proteins optimize T cell responses to foreign antigens, promoting proliferation, lymphokine secretion, upregulation of cell-cell interaction molecules, and efficient B cell antibody secretion. ICOS is essential for efficient communication of T cells and B cells and for normal antibody responses to T cell-dependent antigens. ICOS Protein, Mouse (HEK293, Fc) is the recombinant mouse-derived ICOS protein, expressed by HEK293 , with C-hFc labeled tag.

研究背景

ICOS蛋白增强T细胞对外源抗原的所有基本反应,包括增殖、淋巴因子分泌、细胞间相互作用分子的上调,并为B细胞分泌抗体提供有效帮助。它对于促进 T 细胞和 B 细胞之间的有效通讯以及对 T 细胞依赖性抗原的正常抗体反应至关重要。虽然它不会增加白细胞介素 2 的产生,但它会促进白细胞介素 10 的合成。此外,它还可以防止预激活 T 细胞凋亡,并在 CD40 介导的免疫球蛋白同种型类型转换中发挥关键作用。ICOS 以同二聚体形式存在,通过二硫键连接。

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
