CD34 Class II (Dako Omnis)

CD34 is a single-chain transmembrane protein of approximately 116 kDa, expressed on immature hematopoietic stem/progenitor cells, capillary endothelial cells, embryonic fibroblasts and rare glial cells in nervous tissue. CD34 is a stage-specific, rather than a lineage-specific, leucocyte differentiation antigen. The antibody is a useful aid for classificaction of vascular and lymphatic tumors and for the subclassification of leukemias.
