白细胞共同抗原抗体概述:
B淋巴细胞在抗原的刺激下,能够分化、增殖形成具有针对这种抗原分泌特异性抗体的能力。B细胞的这种能力和量是有限的,不可能持续分化增殖下去,因此产生免疫球蛋白的能力也是极其微小的。将这种B细胞与非分泌型的骨髓瘤细胞融合形成杂交瘤细胞,再进一步克隆化,这种克隆化的杂交瘤细胞是既具有瘤细胞的无限分裂的能力,又具有产生特异性抗体的B淋巴细胞的能力。将这种克隆化的杂交瘤细胞进行培养或注入小鼠腹水内即可获得大量的高效、单一的特异性抗体。这种技术即称为单克隆抗体技术。

产品介绍 CD45 is a family of single chain transmembraneous glycoproteins consisting of at least four isoforms (220, 205, 190, 180 kDa) which share a common large intracellular domain. Their extracellular domains are heavily glycosylated. The different isoforms are produced by alternative messenger RNA splicing of three exons of a single gene on chromosome 1. CD45 is expressed on cells of the human hematopoietic lineage (including hematopoietic stem cells) with the exception of mature red cells. It is not detected on differentiated cells of other tissues. It is likely that CD45 plays an important role in signal transduction, inhibition or upregulation of various immunological functions. Antibodies recognising a common epitope on all of the isoforms are termed CD45 whilst those recognising only individual isoforms are termed CD45RA or CD45RO etc.
Function : Membrane. Membrane raft. Colocalized with DPP4 in membrane rafts.
Similarity : Belongs to the protein-tyrosine phosphatase family. Receptor class 1/6 subfamily.
白细胞共同抗原抗体CD45在活化信号转导中起到调节作用 在确定CD45为一种PTPase之前就已证实了CD45参于细胞的活化和生长调节。抗CD45抗体可以抑制PHA或CD3交联所介导的T细胞增殖,还可抑制NK或细胞毒性T细胞对靶细胞的杀伤,抑制经CD2、CD3以及CD8膜分子介导的信号转导作用。
