大鼠抗小鼠 CD45 抗体(克隆号 YW62.3) 可识别小鼠 CD45 细胞表面抗原,该抗原是一种单次跨膜 I 型糖蛋白,亦称为蛋白酪氨酸磷酸酶受体 C 型(PTPRC),最初被命名为白细胞共同抗原(LCA)。CD45 是一种在所有白细胞表面表达的 180-220 kDa 糖蛋白。

在小鼠中,CD45 由 3 个等位基因编码,各近交系存在差异表达。Ly5 基因最初被定义为:C57BL/6 品系表达其基因产物 LY5.1,SJL 品系表达 Ly5.2;后续研究发现第三个编码 Ly5.3 的等位基因。1987 年发生命名调整:C57BL/6 品系的等位基因改为 Ly5b(编码 Ly5.2),SJL 小鼠的等位基因改为 Ly5a(编码 Ly5.1)。1992 年进一步更名:Ly5.1 改为 CD45.1(SJL),Ly5.2 改为 CD45.2(C57BL/6)。最后,研究证实 CD45 抗原与受体相关蛋白酪氨酸磷酸酶具有同源性,CD45a 基因被重命名为 Ptprca,CD45b 被重命名为 Ptprcb。

小鼠白细胞表达多种 CD45 亚型,其差异取决于三个外显子(A、B、C)的选择性剪接模式,这些外显子编码位于 CD45 胞外区 N 端约 50 个氨基酸的区域。这些限制性表达的蛋白称为 CD45R,其命名依据所表达的密码子产物而定。

大鼠抗小鼠 CD45 抗体(克隆号 YW62.3)能够与小鼠所有 CD45 亚型发生反应。

注:已观察到该抗体与人体组织存在一定的交叉反应性。

Rat anti Mouse CD45 antibody, clone YW62.3 recognizes the murine CD45 cell surface antigen, a single pass type1 transmembrane glycoprotein also known as protein tyrosine phosphatase receptor type C (PTPRC) and originally termed Leucocyte Common Antigen (LCA). CD45 is a 180-220kDa glycoprotein expressed by all leucocytes.

CD45 is encoded by 3 alleles in mice, differentially expressed by various inbred strains. The Ly5 gene was originally described with the gene product LY5.1 expressed in C57bl/6 and Ly5.2 expressed in SJL strains (Komura et al. 1975), this was subsequently expanded to include a third allele encoding Ly5.3 (Shen et al. 1986). Further, in 1987 a reversal of nomenclature was instigated resulting in the allele in C57bl/6 becoming Ly5b encoding Ly5.2 and the allele in SJL mice becoming Ly5a encoding Ly5.1 (Morse et al. 1987). Further changes were made in 1992 with Ly5.1 becoming CD45.1 (SJL) and Ly5.2 becoming CD45.2 (C57bl/6). Finally, following work demonstrating homology between the CD45 antigen and a receptor linked protein tyrosine phosphatase the CD45a gene was renamed Ptprca and CD45b renamed Ptprcb (Charbonneau et al. 1988; Zebedee et al. 1991).

A number of different isoforms of CD45 are expressed on murine leucocytes depending on the pattern of alternative splicing of 3 exons termed A, B and C encoding regions of ~ 50 amino acids located at the N terminal region of the extracellular portion of CD45. The restricted proteins are termed CD45R with a designation depending on the expressed codon product. (Birkeland et al. 1989).

Rat anti mouse CD45 antibody, clone YW62.3 is reactive with all isoforms of murine CD45.

N.B. Some reactivity with human tissue has been observed.
