CD34 in KG-1 Human Cell Line. CD34 was detected in immersion fixed KG-1 human acute myelogenous leukemia cell line using Mouse Anti-Human CD34 AlexaFluor® 488-conjugated Monoclonal Antibody (Catalog # FAB7227G, green) at 10 μg/mL for 3 hours at room temperature and counterstained with DAPI (blue). Specific staining was localized to cell surfaces and cytoplasm. View our protocol for Fluorescent ICC Staining of Non-adherent Cells.

Background: CD34

The CD34 family of cell surface transmembrane proteins includes the hematopoietic progenitor cell antigen CD34, Podocalyxin, and Endoglycan. This single-pass sialomucin‑like transmembrane protein is heavily glycosylated and phosphorylated by Protein Kinase C (PKC). CD34 is a 115 kDa glycoprotein found on multipotent precursors, bone marrow stromal cells, embryonic fibroblasts, vascular endothelia, as well as some populations of mesenchymal stem cells, and tumor cell lines. CD34 is involved in the adhesion of stem cells to the bone marrow extracellular matrix or to stromal cells.
