Background of CD34 antibody

CD34 is a type I transmembrane glycoprotein (Mr = 104-120 kDa) expressed on stem cells, early hematopoietic progenitor cells, bone marrow stroma cells, endothelial cells, embryonic fibroblasts, and neurons.  CD34 analysis can be used for the differential identification of acute leukemias as well as routine analysis of cultured stem cell lines. 
CD34 a type 1 transmembrane protein, belonging to the sialomucin family, has important roles in adhesion which remain to be fully elucidated.  CD34 has an intracellular cytoplasmic domain containing consensus sites for serine, theronine, tryrosine and active protein kinase C (PKC) phosphorylation thereby implicating a role for the protein in signal transduction processes.  CD34 expression, as identified by antibody, is a hallmark for identifying pluripotential hematopoietic stem or progenitor cells.   CD34 antibody positive populations expand and differentiate into the various lymphohematopoietic lineages.  During differentiation, lineages lose CD34 expression and become CD34 antibody negative.
CD34 is also expressed on vascular endothelium, bone marrow stroma, embryonic fibroblasts, and neurons and antibody to CD34 is also useful in analyzing these populations.  Positive staining has also been described in a number of malignancies including various sarcomas and fibromas, preB-ALL, peripheral nerve sheath tumors, and papillary thyroid carcinoma.  If certain kinds of tumors are characteristically positive for CD34 antibody staining such as Ewing’s sarcoma, a CD34 antibody negative result may potentially rule out that particular tumor.
