描述

The NKG2D/CD314 protein serves as a key activating and costimulatory receptor in immune surveillance, binding to multiple stress-inducing ligands on tumor and virus-infected cells.It plays a dual role by stimulating NK cells and enhancing T cell activation in CD8(+) T cell-mediated adaptive responses.NKG2D/CD314 Protein, Human (HEK293, Fc) is the recombinant human-derived NKG2D/CD314 protein, expressed by HEK293 , with C-hFc labeled tag.

研究背景

NKG2D/CD314 蛋白作为免疫监视所必需的激活和共刺激受体,与自体肿瘤细胞和病毒感染细胞上存在的多种细胞应激诱导配体结合。它在先天免疫反应中发挥双重作用,既刺激激活杀伤 (NK) 细胞,又在 CD8(+) T 细胞介导的适应性免疫反应中充当 T 细胞受体 (TCR) 的共刺激受体,从而增强 T 细胞激活。该受体促进穿孔素介导的配体表达肿瘤细胞的消除,其信号级联涉及钙内流,最终导致 TNF-α 表达。此外,NKG2D/CD314 参与 NK 细胞介导的骨髓移植排斥反应,并可能调节 NK 细胞的分化和存活。其配体结合能力延伸至 MHC I 类相关糖蛋白的各个亚家族,包括 MICA、MICB、RAET1E、RAET1G、RAET1L/ULBP6、ULBP1、ULBP2、ULBP3 (ULBP2>ULBP1>ULBP3) 和 ULBP4。该蛋白通过二硫键连接形成同二聚体,并与 HCST/DAP10 亚基形成异六聚体,这是 NK 细胞表面表达和细胞毒性诱导的关键相互作用。此外,它可以与 CD94 建立二硫键异二聚体,并与 CEACAM1 相互作用,招募 PTPN6 进行 VAV1 去磷酸化,同时不与 TYROBP 相互作用。

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
