[供應]10311-25-500-BioGems CD28單克隆抗體，SAFIRE 純化級
BioGems的SAFIRE （Sodium Azide Free Immensely Reduced Endotoxins） 類產品是BioGems品牌下的功能性抗體產品，經特殊工藝生產、純化，可用于免疫細胞功能的激活、阻斷、中和研究。
SAFIRE純化CD28單抗 （clone: CD28.2）是 T細胞激活、增殖的輔助刺激分子。
Anti-Human CD28 SAFIRE Purified CD28單抗
產品英文名稱：Anti-Human CD28 SAFIRE Purified
產品中文名稱：CD28單克隆抗體/抗人CD28抗體
BioGems CD28單抗特點
極低的內毒素含量，低于0.01EU/μg蛋白
不含疊氮鈉，適用于體內或體外實驗
高蛋白純度
應用 BioGems CD28單抗適用細胞：T細胞
作用機理 CD28單克隆抗體特異性地與人類44 kDa同源二聚體跨膜糖蛋白CD28結合，CD28在大多數成熟的T淋巴細胞、漿細胞和胸腺細胞的表面表達。CD28是B7-1(CD80)和B7-2(CD86)的配體，T淋巴細胞的共刺激分子，并能增強T和B淋巴細胞間的相互作用。據報道，T淋巴細胞刺激產生IL-2依賴于單克隆抗體,這表明CD28分子呈現出具有不同功能的亞區域。CD28單克隆抗體誘導Ca2+流入Jurkat T淋巴細胞。其他研究表明CD28與信號轉導有關。
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.
質量控制
BioGems CD28單克隆抗體經過親和層析純化。
內毒素水平：蛋白質小于0.01 EU/µg，鱟試劑法檢測。

CD3/CD28功能性抗體應用：CAR-T及免疫細胞研究
CAR-T介紹
通過增強免疫系統對腫瘤的反應來治療癌癥的腫瘤免疫療法被認為具有巨大的臨床應用前景。其中的過繼性免疫療法—CAR-T療效 法，正受到科研與臨床的極大關注，已有多家研究機構 (如Baylor, Fred Hutchinson, NCI)展開臨床研究，而今年FDA更是已經批準了諾華和Kite兩款CAR-T治療藥物。

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.
