Anti-CD34 Antibody

CD34 serves as a defining surface marker for hematopoietic stem and progenitor cells, with strong expression on vascular endothelium and emerging roles in fibrocyte biology and tumor angiogenesis research. This unconjugated Rabbit polyclonal IgG antibody targets the human CD34 antigen and is supplied at 200 µl by Antibodies.com for use in Western blot and immunofluorescence workflows.

The reagent is generated in Rabbit and shows confirmed reactivity toward human, mouse, and rat CD34. In Western blot, it yields a band consistent with the expected molecular weight of the CD34 glycoprotein in endothelial and hematopoietic cell lysates. For immunofluorescence on fixed cells or cryosections, it localizes CD34-positive progenitors, capillary networks, and tumor-associated vasculature within tissue architecture.

Common applications include characterization of stem cell populations from umbilical cord blood or bone marrow, studies of tumor angiogenesis, vascular biology investigations, and research on hematological disorders. The unconjugated format supports flexible pairing with fluorophore- or enzyme-conjugated secondary antibodies across diverse detection platforms.
