TIGIT 蛋白, Cynomolgus (HEK293, Fc)

目录号: HY-P76674
产品使用指南

TIGIT 是 Ig 超家族的一种受体,在限制适应性免疫和先天免疫中起关键作用。TIGIT 可以作为免疫调节剂,抑制T细胞和 NK 细胞的活性,并且还调癌症细胞的识别。TIGIT 由细胞外免疫球蛋白 (Ig) 可变结构域、1 型跨膜结构域和具有两个抑制基序的细胞质尾部组成。TIGIT Protein, Cynomolgus (HEK293, Fc) 是重组的 TIGIT 蛋白,由 HEK293 表达,带有 C-hFc 标签。TIGIT Protein, Cynomolgus (HEK293, Fc) 全长 183 个氨基酸,分子量约为 ~47.2 kDa。

描述

TIGIT is a receptor of the Ig superfamily that plays a key role in restricting adaptive and innate immunity. TIGIT can be used as an immune modulator to inhibit the activity of T cells and NK cells, and also regulates the recognition of cancer cells. TIGIT consists of an extracellular immunoglobulin (Ig) variable domain, a type 1 transmembrane domain, and a cytoplasmic tail with two inhibitory motifs. TIGIT Protein, Cynomolgus (HEK293, Fc) is the recombinant cynomolgus-derived TIGIT protein, expressed by HEK293 , with C-hFc labeled tag. The total length of TIGIT Protein, Cynomolgus (HEK293, Fc) is 183 a.a., with molecular weight of ~47.2 kDa.

研究背景

TIGIT 与脊髓灰质炎病毒受体 (PVR) 或 PVR2 结合,能抑制 T 和自然杀伤 (NK) 细胞的活性。此外,TIGIT 还调节癌症细胞的识别。因此 TIGIT 被认为是癌症免疫治疗的一个有前途的靶点。TIGIT 有三种配体:CD155、CD112 和 CD113。TIGIT 与 CD155 结合能促进 T 细胞反应的直接和间接下调。总之 TIGIT 可以作为免疫调节剂在限制适应性免疫和先天免疫中起关键作用 [1][2][3]

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
