Human CD45RA is expressed on all cells of hematopoietic origin, except erythrocytes. CD45RA is a transmembrane tyrosine phosphate which can exist in at least nine different isoforms resulting from tissue-specific alternative RNA splicing of exons 4-7 of a single gene coding for the various N-terminal peptide segments. The CD45RA isoform predominates on naive/resting T cells and medullary thymocytes.

FCM: 20 µl/1 million cells. Optimal dilutions/concentrations should be determined by the end user. |
| Immunogen |
Tissue / cell preparation (Human). Fresh human lymph node lymphocytes depleted of surface immunoglobulin positive cells were used as the immunogen. This antigen is a single chain glycoprotein which is expressed on B cells, monocytes, and T cell subsets. |

| Specificity |
The HI100 monoclonal antibody reacts with human CD45RA, a 220 kDa molecule expressed by subpopulations of CD4+ peripheral Tlymphocytes, CD8+ peripheral T lymphocytes, and B cells. The CD45RA+ T cell populations are mainly naive/virgin allowing the use of HI100mAb as a phenotypic marker to discriminate T cell subsets. |
