Clone Host Grade Applications
Monoclonal Mouse Affinity Purified IH
CD34, a single chain transmembrane glycoprotein, is selectively expressed on human lymphoid and myeloid hematopoietic progenitor cells. This antibody is of value in the study of benign and malignant vascular tumors as well as characterization of leukemias. Staining for CD34 has been used to measure angiogenesis, which reportedly predicts tumor recurrence.
Catalog #C2386-10
