The CD34, clone HM34, PE conjugate is a Armenian hamster monoclonal antibody (mAb) that recognizes the CD34 antigen. R-PE (phycoerythrin) is a stable and highly soluble phycobiliprotein which provides maximal absorbance and fluorescence without susceptibility to internal or external fluorescence quenching; thus, this flouroescent protein provides exceptional quantum yields and molar extinction coefficients. Use of PE in antibody conjugates gives probes greatly enhanced detectability.


Specific for CD34
CD34 (cluster of differentiation 34) is a cell surface glycoprotein that functions as a cell-cell adhesion factor and is also a type I monomeric sialomucin-like glycophosphoprotein. It is expressed selectively on most hematopoietic stem cells, embryonic fibroblasts, bone marrow stromal cells, capillary endothelial cells, testicular cells, and some nervous tissue. Although little is known about its exact function, CD34 is required for T-cells entry into lymph nodes. CD34 is expressed on lymph node endothelia whereas its ligand CD62L (L-selectin), to which it binds, is on the T cell. However, under other circumstances CD34 has been shown to block mast cell adhesion or facilitate the opening of vascular lumens. Regardless of their mode of action, under all circumstances CD34 has been shown to facilitate cell migration.
