PD-1 蛋白, Rat (HEK293, Fc)

目录号: HY-P73348
产品使用指南

程序性细胞死亡蛋白 1 (Pdcd1) 是一种免疫抑制受体,通过结合配体 CD274/PDCD1L1 和 CD273/PDCD1LG2 传递抑制信号,在诱导和维持自身免疫耐受中发挥关键作用。Pdcd1 在抗肿瘤免疫和自身保护免疫中发挥作用,但也被肿瘤利用 Pdcd1 介导的抑制途径来减弱抗肿瘤免疫。PD-1 蛋白, Rat (HEK293, Fc) 是重组的 PD-1 蛋白,由 HEK293 表达,带有 C-hFc 标签。PD-1 蛋白, Rat (HEK293, Fc) 全长 167 个氨基酸,分子量分别约为 ~118.8 & 58.4 kDa。

描述

Programmed cell death protein 1 (Pdcd1) is an immune-inhibitory receptor which delivers inhibitory signals upon binding to ligands CD274/PDCD1L1 and CD273/PDCD1LG2, playing a critical role in induction and maintenance of immune tolerance to self. Pdcd1plays a role in anti-tumor immunity and is involved in safeguarding against autoimmunity, but Pdcd1-mediated inhibitory pathway is also exploited by tumors to attenuate anti-tumor immunity. PD-1 Protein, Rat (HEK293, Fc) is the recombinant rat-derived PD-1 protein, expressed by HEK293 , with C-hFc labeled tag. The total length of PD-1 Protein, Rat (HEK293, Fc) is 167 a.a., with molecular weight of ~118.8 & 58.4 kDa, respectively.

研究背景

程序性细胞死亡蛋白 1 (Pdcd1) 是一种免疫抑制受体,在活化的 T 细胞中表达,通过结合配体 CD274/PDCD1L1 和 CD273/PDCD1LG2 传递抑制信号。Pdcd1 参与 T 细胞功能的调控,包括效应CD8+ T 细胞功能的调控,Pdcd1 蛋白还能促进 CD4+ T 细胞向 T 调节性细胞分化,在诱导和维持自身免疫耐受中发挥关键作用。Pdcd1 在包括黑色素瘤在内的许多类型的肿瘤中表达,并在抗肿瘤免疫中发挥作用。此外,Pdcd1 也参与自身保护免疫,然而,它也有助于抑制有效的抗肿瘤和抗微生物免疫,因为肿瘤利用 Pdcd1 介导的抑制途径来减弱抗肿瘤免疫,逃避免疫系统的破坏,从而促进肿瘤生存[1][2]

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
