Anti-CD45 Antibody, clone F10-89-4

半岛bd体育手机客户端 说明

一般描述

CD45 is a receptor-tyrosine phosphatase required for antigen-induced signaling in T-cells and B-cells; its substrates are unknown. Interestingly, it associates with several Src-family tyrosine kinases, which are inhibited by tyrosine phosphorylation in their c-termini, suggesting a mechanism for signaling by CD45.

特异性

This antibody reacts with the leucocyte common antigen (LCA) complex to be found on lymphocytes, monocytes, granulocytes, thymocytes and malignant T and B cells. No reactivity has been observed with primary or metastatic carcinoma cells. Plasma cells or myeloma cells may have weak expression or be negative for this antigen.
The LCA comprises of at least 5 isoforms ranging from 180-220 kDa which are produced as a result of alternative splicing of exons A, B or C. CBL 124 recognizes epitopes common to
all of the isoforms.
Antigen distribution:
Thymocytes >95%
Granulocytes >95%
Monocytes >95%
B cells (CD20+) >95%
T cells (CD3+) >95%
NK cells (CD16+) >95%
Peripheral blood lymphocytes >95%
FUSION PARTNER: NS1 myeloma cell line

免疫原

Purified T cells from human lymph nodes
