General description
Hematopoietic progenitor cell antigen CD34 (UniProt: P28906; also known as CD34) is encoded by the CD34 gene (Gene ID: 947) in human. CD34 is a highly glycosylated single-pass type I membrane protein that is selectively expressed on hematopoietic progenitor cells and the small vessel endothelium of a variety of tissues. It is predominantly regarded as a marker of hematopoietic stem cells and hematopoietic progenitor cells. L-Selectin (CD62L) is the most commonly described ligand for CD34. CD34 serves as an adhesion molecule that plays a role in early hematopoiesis by mediating the attachment of stem cells to the bone marrow extracellular matrix or directly to stromal cells. It is also reported to act as a scaffold for the attachment of lineage specific glycans, allowing stem cells to bind to lectins expressed by stromal cells or other marrow components. Under normal conditions, CD34+ expressing cells account for about 1 to 2% of the total bone marrow cells. CD34 is synthesized with a signal peptide (aa 1-31), which is subsequently cleaved off to produce the mature form. The mature form contains an extracellular domain (aa 32-290), a transmembrane domain (aa 291-311), and cytoplasmic domain (312-385). The extracellular domain that is heavily sialylated and O-linked glycosylated and contains some N-linked glycosylation sites. Two isoforms of CD34 have been described that are produced by alternative splicing. This ZooMAb recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
