CD45 glycoprotein have various molecular weights on various cell types: B-cell 240 kDa, thymocytes 180 kDa, T-cell multiple bands. Reduced in PAGE gels: 180 and 240 kDa. Relevant epitopes are termed CD45RA (exon 4), CD45 RB (exon 5, CD45RC (exon 6) and CD45R or CD45RO (exons 4-6 spliced out). 158-4D3 was clustered in Boston at the Vth International CD workshop as anti CD45RA, useful to differentiate "naive" T-cells from activated (CD45R0+ve) T-cells, or to differentiate T-cell lymphomas (CD45R0+ve) from B-cell lymphomas (CD45RA+ve).

Positive control: Daudi, Raji, IM9 and human lymphocytes. Human lymph node and tonsil.
