Anti-CD34 Antibody

CD34 is a 110-120 kDa transmembrane sialomucin glycoprotein widely used as a phenotypic marker for hematopoietic stem and progenitor cells, vascular endothelium, and emerging populations of cancer stem cells. This unconjugated rabbit polyclonal reagent from Antibodies.com binds CD34 on both human and mouse samples, supporting translational research into bone marrow reconstitution, angiogenic signaling, tumor vascularization, and stromal biology.

The antibody is supplied as 100 µl of polyclonal antiserum raised in rabbit, validated for Western blot and ELISA workflows. Researchers apply it to track endothelial progenitor recruitment in murine injury models, isolate CD34-positive fractions from cord blood or mobilized peripheral blood mononuclear cells, and probe CD34 expression patterns in leukemic blasts and solid tumor sections. The unconjugated format allows flexible pairing with HRP, biotin, or fluorophore-conjugated secondary reagents depending on the detection platform, making it adaptable to standard laboratory assays in vitro and in research use only settings.
