Anti-CD34 Antibody

CD34 is a transmembrane phosphoglycoprotein best known as a hallmark surface marker for hematopoietic stem and progenitor cells, with additional expression on vascular endothelium and subsets of fibroblasts. Antibodies.com supplies this anti-CD34 reagent as an unconjugated rabbit polyclonal IgG, formulated as a 100 µl liquid and validated for western blot and immunofluorescence workflows, with reactivity confirmed across human, mouse, and rat samples.

Researchers commonly pair this primary antibody with fluorescent or HRP-conjugated secondaries when profiling CD34-positive populations in fixed tissue sections and whole-cell lysates. Typical applications include tracking hematopoiesis, characterizing vascular networks in tumor angiogenesis models, and following stem cell populations in regenerative biology research, with downstream readouts spanning western blot signal quantification and immunofluorescence microscopy of CD34-expressing cells.
