高蛋白纯度
应用 BioGems CD28单抗适用细胞：T细胞
作用机理 CD28单克隆抗体特异性地与人类44 kDa同源二聚体跨膜糖蛋白CD28结合，CD28在大多数成熟的T淋巴细胞、浆细胞和胸腺细胞的表面表达。CD28是B7-1(CD80)和B7-2(CD86)的配体，T淋巴细胞的共刺激分子，并能增强T和B淋巴细胞间的相互作用。据报道，T淋巴细胞刺激产生IL-2依赖于单克隆抗体,这表明CD28分子呈现出具有不同功能的亚区域。CD28单克隆抗体诱导Ca2+流入Jurkat T淋巴细胞。其他研究表明CD28与信号转导有关。
Description
The CD28.2 monoclonal antibody specifically binds with the human 44 kDa homodimeric trans-membrane glycoprotein CD28, expressed on the surface of most mature T lymphocytes, plasma cells, and thymocytes. CD28 is a ligand for B7-1 (CD80) and B7-2 (CD86), a co-stimulator of T lymphocytes, and enhances the interaction between T and B lymphocytes. It has been reported that the T lymphocytes stimulation to produce IL-2 depends on the monoclonal antibody involved, which suggests that the CD28 molecule presents some subregions with distinct functions. The CD28.2 antibody induces Ca2+ influx in Jurkat T lymphocytes. Other studies have shown that CD28 is involved in the signal transduction.

CD3/CD28功能性抗体应用：CAR-T及免疫细胞研究
CAR-T介绍
通过增强免疫系统对肿瘤的反应来治疗癌症的肿瘤免疫疗法被认为具有巨大的临床应用前景。其中的过继性免疫疗法—CAR-T疗效 法，正受到科研与临床的极大关注，已有多家研究机构 (如Baylor, Fred Hutchinson, NCI)展开临床研究，而今年FDA更是已经批准了诺华和Kite两款CAR-T治疗药物。

The CD28.2 antibody induces Ca2+ influx in Jurkat T lymphocytes. Other studies have shown that CD28 is involved in the signal transduction.
Preparation & Storage
The product should be stored undiluted at 4°C. Do not freeze. The monoclonal antibody was purified utilizing affinity
chromatography. The endotoxin level is determined by LAL test to be less than 0.01 EU/µg of the protein.
Application Notes
The antibody has been analyzed for quality through the flow cytometric analysis of the relevant cell type. It is recommended that the reagent be titrated for optimal performance for each application.
