2.2.1 CD-28 CD28 is a most effective and co-stimulatory receptor expressed on T cells and binds to ligand CD80/CD86. CD28 is important for the proliferation and efficacy of T-cell immune responses. Chromosome 2q33.2 is the location of the CD28 gene. In the Iranian population, the subclini...
基于独具技术优势的哺乳动物细胞表达平台,我司自主研制的GMP级CD3(货号:GMP-TL101)、CD28(货号:GMP-TL102)、CD16(货号:GMP-TL201)等单克隆抗体,均有正确的翻译后修饰(例如,二硫键、糖基化及磷酸化等),与天然抗体类似性高、活性强、效果好、稳定性高。同时,我司可按客户需要对抗体的相关基因进行突变或重组改...
CD28 and CTLA-4 (CD152) are also members of the immunoglobulin (Ig) superfamily. CD28 is expressed on nearly all CD4+ T cells and about half of the CD8+ T cells.1, 14 It is also expressed on developing thymocytes. CTLA-4 is not constitutively expressed; rather, it is rapidly up-regu...
CD4+ Treg cells can secret inhibitory cytokine to exert their suppressive function18. Cell surface expression of both CD39 and CD73 on CD4 T cells is also linked to their suppressive function19, which is mediated by CD39 and CD73 through conversion of ATP/ADP to AMP and AMP to adenosine,...
与T细胞识别、黏附和活化有关CD分子的结构 在外周血淋巴细胞中,CD28+细胞占54%一86%,包括几乎所有的CD4+T细胞和约50%的CD8+T细胞。此外,浆细胞和部分活化B细胞也可表达CD28。CD28分子的配体是B?—1(CD80)和B7—2(CD86)。CD28分子V样区中高度保守的MYPPPY基序是与B7分子结合的部位。CD28分子的胞质区带有ITAM,...
③BTLA、CD272结构上与CTLA-4和PDl相似,胞质区有2个ITIM,主要表达于活化的Thl细胞,其配体为TNFRSF的HVEM,BLTA结合HVEM后,ITIM中的酪氨酸发生磷酸化,募集SHP-1和SHP-2,抑制T细胞的活化。 CD28 (Cluster of Differentiation 28) is one of the molecules expressed on T cells that provide co-stimulatory signa...

Lymphocyte purity was evaluated on PBMC by the expression CD45 (Table S2) and was > 99%. The rationale for this approach was to avoid the potential interference of flow cytometry mAbs with Rhapsody mAbs, according to guidelines provided by the manufacturer. Approximately 35.000 to 350.000 ...
