{"product_id":"v2238-100ug","title":"CD45RA Antibody (Leukocyte marker)","description":"\u003cp\u003eThis antibody recognizes a protein of 205kDa-220kDa, identified as CD45RA, an isoform of the human leukocyte common antigen (CD45). Human CD45 contains three exons which encode peptide segments designated A, B and C. 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+ Tcells, 50% of peripheral CD8+ T-cells, B-cells, and leukemic B-cell lines. T-cells expressing CD45RA are naive or virgin Tcells. T-cells expressing CD45RO are memory Tcells. CD45RA and CD45RO define complementary, predominantly non-overlapping populations of resting peripheral Tcells. This CD45RA antibody is useful in the study of the subpopulation of CD4+ or CD8+ T-cells. It is especially useful in differentiating T-cell lymphomas (CD45RO +ve) from B cell lymphomas (CD45RA +ve).\u003c\/p\u003e","brand":"NSJ Bioreagents","offers":[{"title":"100 ug \/ Mouse","offer_id":49474935488792,"sku":"V2238-100UG","price":539.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/get_image_9d9f7e73-de37-4960-a557-ff9725341500.jpg?v=1734444034","url":"https:\/\/danabiosci.com\/products\/v2238-100ug","provider":"Dana Bioscience","version":"1.0","type":"link"}
