Monoclonal Anti-Human CD28 Antibody, premium grade
抗體來源(Source)
Monoclonal Anti-Human CD28 Antibody, premium grade (CD8-M120b) is recombinantly produced from human 293 cells (HEK293).
專為臨床前期設(shè)計(jì)的premium級單克隆抗人CD28抗體(CD8-M120b)具有與GMP單克隆抗人CD28抗體(GMP-MC2824)相同的活性和性能,可實(shí)現(xiàn)從臨床前開發(fā)到臨床階段的無縫過渡。在原材料安全不是首要任務(wù)的早期開發(fā)階段,premium產(chǎn)品為GMP產(chǎn)品提供了一種經(jīng)濟(jì)高效的替代品。通過在早期開發(fā)階段使用Premium Grade產(chǎn)品,您可以輕松過渡到臨床和商業(yè)階段,而無需重新驗(yàn)證原材料和修改制造工藝。

背景(Background)
T細(xì)胞特異性表面糖蛋白CD28也稱為TP44,是一種單程I型膜蛋白,含有一個(gè)Ig樣V型(免疫球蛋白樣)結(jié)構(gòu)域。是T細(xì)胞上表達(dá)的提供T細(xì)胞活化所需的共刺激信號的分子之一。CD28是CD80(B7.1)和CD86(B7.2)的受體。當(dāng)被Toll樣受體配體激活時(shí),CD80在抗原呈遞細(xì)胞(APCs)中的表達(dá)上調(diào)??乖蔬f細(xì)胞上的CD86表達(dá)是組成型的。CD28是唯一在幼稚T細(xì)胞上組成型表達(dá)的B7受體。
