Clone: BHKG-2.
Background: CD45RA recognizes Mr. 220-kdalton of the leucocyte antigen (LCA). CD45RA antigen is a member of the CD45 antigen family that also includes CD45, CD45RO, and CD45RB antigens. CD45RA is expressed on approximately 75% of CD8 lymphocytes and 50% of CD4 lymphocytes, all B cells and NK Cells. CD45RA antigen is expressed on naive T lymphocytes, antigen density decreases upon in vitro activation. A decrease antigen density has been demonstrated for CD4+CD45RA+subset with active multiple sclerosis.
Immunogen: Derived from the hybridization of mouse NS-1 myeloma cells with spleen cells of BALB/c mice immunized with peripheral blood monocytes from rheumatoid arthritis patient.
Purification Method: Protein A/G Chromatography.
Formulation: Provided as solution in phosphate buffered saline with 0.08% sodium azide.
