CD34 antibodies

CD34 is a cell-surface glycoprotein type 1 transmembrane protein that belongs to the sialomucin family. CD34 comprises of an intracellular cytoplasmic domain with consensus sites for serine, threonine, tyrosine and active protein kinase C (PKC). Because it is differentially glycosylated within different cell types, it has a range of apparent molecular weight sizes. It is a marker for pluripotent hematopoietic stem or progenitor cells and has been extensively used to isolate and characterize these progenitor cells.

CD34 is a cell surface glycoprotein that aids cells in cell-cell adhesion. It is expressed on endothelial cells where it is known to bind L-selectin and may aid in migration of T-cells.
