CD45RA [clone 4KB5], anti-human

Description: CD45 or Leukocyte Common Antigen (LCA/T200) belongs to a family of membrane sialoglycoproteins with MW of 180kDa-220kDa. Human CD45 contains three exons which encode peptidesegments designated A, B and C, respectively. The differential splicing of the exons generates various isoforms. CD45RA.is a single chain glycoprotein. It is expressed on appoximately 40-50% of peripheral CD4+ T-cells, 50% of peripheral CD8+ T-cells, B-cells, and leukemic B-cell lines. T-cells expressing CD45RA and CD45RO define complementary, predominantly non-overlapping populations of resting peripheral T-cells. CD45RA are naive orvirgin T-cells while, T-cells expressing CD45RO are memory T-cells.Localization: membraneDilution: 25-100Positive Control: tonsil, lymph nodeHIER: citrate pH6.0Status: RUO
