Anti-human PD-1 mAb 抗人PD-1单克隆抗体

目录号 M11385 所有产品仅供科研使用,严禁用于人或动物的治疗等任何其他用途,不为任何个人提供产品和服务  


生物活性:PD-1 主要在激活的 T 细胞和 B 细胞中表达,功能是抑制细胞的激活,这是免疫系统的一种正常的自穏机制,因为过度的 T/B 细胞激活会引起自身免疫病,所以 PD-1 是我们人体的一道护身符。

生物活性:PD-1 主要在激活的 T 细胞和 B 细胞中表达,功能是抑制细胞的激活,这是免疫系统的一种正常的自穏机制,因为过度的 T/B 细胞激活会引起自身免疫病,所以 PD-1 是我们人体的一道护身符。但是,肿瘤微环境会诱导浸润的 T细胞高表达 PD-1 分子,同时肿瘤细胞也会高表达 PD-1 的配体 PD-L1 和 PD-L2,导致肿瘤微环境中 PD-1 通路持续激活,造成 T 细胞功能被抑制,而无法起到杀伤肿瘤细胞的目的 PD-1 的抗体就可以阻断这一通路,从而起到部分恢复 T 细胞的功能,使 T 细胞能够继续杀伤肿瘤细胞。因此我们将抗人 PD-1 单克隆抗体在体外对扩增 T 细胞进行“封闭”作用,从而明显提高免疫细胞在患者听对肿瘤的杀伤作用。

Vaspin (Visceral Adipose-Specific SERPIN) is a newly described adipokine. Vaspin is also a unique insulin sensitizing adipocytokine in obesity.

Recombinant Human B2M Protein (Mammalian, C-6His)

β-2-Microglobulin (B2M) is a secreted protein with 1 Ig-like C1-type (immunoglobulin-like) domain which belongs to the beta-2-microglobulin family. B2M may adopt the fibrillar configuration of amyloid in certain pathologic states.

Recombinant Mouse E-Selectin/CD62E Protein (HEK293)

E-selectin, also known as endothelial leukocyte adhesion molecule-1 (ELAM-1) and CD62E, is an inducible adhesion molecule that is expressed on the surfaces of stimulated vascular endothelial cells and is sometimes involved in cancer cell metastasis.

Recombinant Human DPP4/CD26 (Mammalian, C-6His)

DPP4/CD26 is a signal-anchor for type II membrane protein that belongs to the peptidase S9B family. DPP4/CD26 acts as a positive regulator of T-cell coactivation, by binding at least ADA, CAV1, IGF2R, and PTPRC. It’s binding to CAV1 and CARD11 induces T-cell proliferation and NF-kappa-B activation in a T-cell receptor/CD3-dependent manner.
