背景介绍
Protein tyrosine phosphatase receptor type C (PTPRC) is also known as CD45 antigen, which was originally called leukocyte common antigen (LCA). CD45 is an enzyme required for T-cell activation through the antigen receptor consisting of two intracellular phosphatase domains, a transmembrane domain and an extracellular domain. Upon T-cell activation, CD45 recruits and dephosphorylates SKAP1 via an interaction through the first PTPase domain, which is the only domain to possess intrinsic kinase activity. However, both domains are required for appropriate phosphatase and T-cell antigen receptor activity (PMID: 8076596).
What is the molecular weight of CD45?
The molecular weight of CD45 is a 180-240 kDa.
What are the isoforms of CD45?
Six different human isoforms of CD45 have been isolated, containing all three exons (ABC isoform), two of the three exons (AB and BC isoforms), only one exon (A isoform or B isoform), or no exons (O isoform). All of the isoforms have the same eight amino acids at their amino-terminus (PMID: 12412720).
What is the tissue specificity of CD45?
CD45 is a tyrosine phosphatase expressed on the plasma membrane of all hematopoietic cells, except erythrocytes and platelets (PMID: 7803253).
What are the post-translational modifications of CD45?
CD45 can be heavily N- and O-glycosylated (PMID: 1702721).
What is CD45's involvement in disease?
Defects in CD45 are a cause of severe combined immunodeficiency autosomal recessive T-cell-negative/B-cell-positive/NK-cell-positive (T(-)B(+)NK(+) SCID); a severe form of SCID. It is classed by the impairment of both humoral and cell-mediated immunity, leukopenia, and the low or absent levels of antibodies (PMID: 10700239). Also, genetic variants of CD45 have a role in susceptibility to multiple sclerosis (PMID: 12864992).

CD45/CD45RA/CD45RB/CD45RC/CD45RO CD45 常用单克隆抗体或代号： T29/33,BMAC1;(T200,B220) 主要表达细胞： Leu [NL] 分子质量(kDa)和结构： gp180- 240,白细胞共同抗原(LCA) 功 能： PTP酶,调节信号传导 CD45RA 常用单克隆抗体或代号： G1- 15,F8- 11- 13,Leu18,2H4;(限制性LCA) 主要表达细胞： Tsub,B,G,M
抗体的检测外，还应该用与其抗原成分相关的其它抗原进行交叉试验，方法可用ELISA、IFA法。例如：①制备抗黑色素瘤细胞的McAb，除用黑色素瘤细胞反应外，还应该用其它脏器的肿瘤细胞和正常细胞进行交叉反应，以便挑选肿瘤特异性或肿瘤相关抗原的单克隆抗体。②制备抗重组的细胞因子的单克隆抗体，应首先考虑是否与表达菌株的蛋白有交叉反应，其次是与其它细胞因子间有无交叉。 2．McAb的Ig类与亚类的鉴定 一般在用酶标或荧光素标记的第二抗体进行筛选时已经基本上确定了抗体的Ig类型
免疫系统受抗原刺激后，B细胞转化为浆细胞，由浆细胞产生与抗原发生特异性结合的球蛋白，这类球蛋白称为抗体(antibody,Ab)。 免疫球蛋白(immunoglobulim,Ig)是指具有抗体活性或化学结构与抗体相似的球蛋白。 免疫球蛋白普遍存在于哺乳动物和人类的血液、组织液和外分泌中。人体的免疫球蛋白主要有五类：IgM、IgA、IgG、IgD、IgE。 (一) 抗体结构 抗体是具有4条多肽链的对称
