Biolegend, 378602, Purified anti-human CD34 Antibody, 100μg

CD34, also known as gp105-120, is a type I monomeric sialomucin-like glycophosphoprotein with an approximate molecular weight of 105-120 kD. Since it is selectively expressed on the majority of hematopoietic stem/progenitor cells, bone marrow stromal cells, capillary endothelial cells, embryonic fibroblasts, and some nervous tissue, CD34 is a commonly used marker to identify human hematopoietic stem/progenitor cells. According to the differential sensitivity to enzymatic cleavage, four groups of epitopes of CD34 have been described. CD34 mediates cell adhesion and lymphocytes homing through binding to L-selectin and E-selectin ligands. About 40% of acute myeloid leukemias and 65% of pre-B acute lymphoblastic leukemias express CD34, whereas only 1-5% of acute T-lymphoid leukemias are CD34 positive.
