| Specificity: | Recognizes a protein of 205 kDa-220 kDa, identified as CD45RA (Workshop III). CD45RA is isoforms of the human leukocyte common antigen (CD45). Human CD45 contains three exons which encode peptide segments designated A, B and C, respectively. The differential splicing of the exons generates at least five isoforms, ABC, AB, BC, B and O. This antibody reacts with ABC and BC isoforms. CD45RA is expressed on 40-50% of peripheral CD4+ T cells, 50% of peripheral CD8+ T cells, B cells, and leukemic B cell lines. T cells expressing CD45RA are naive or virgin T cells. T cells expressing CD45RO are memory T cells. CD45RA and CD45RO define complementary, predominantly non-overlapping populations of resting peripheral T cells. This monoclonal antibody is useful in study on the subpopulation of CD4+ or CD8+ T cells. It can especially be used to differentiate T cell lymphomas (CD45RO+ve) from B cell lymphomas (CD45RA+ve). |
