Overview

Product Description Biotin-conjugated Mouse Monoclonal antibody [4H11 (APG)] recognizes CD34
Tested Reactivity Hu
Tested Application FACS
Specificity The clone 4H11(APG) reacts with Class III epitope on CD34 (Mucosialin), a 110-115 kDa monomeric transmembrane phosphoglycoprotein expressed on hematopoietic progenitors cells and on the most pluripotential stem cells; it is gradually lost on progenitor cells. 4H11(APG) completely blocks binding of Class II antibody QBEnd10 and Class III antibodies BIRMA K3 and 8G12 on KG1a cell line.
HLDA VI; WS Code M MA58
Host Mouse

Clone 4H11 (APG)
Isotype IgG1
Target Name CD34
Antigen Species Human
Immunogen Permanent human cell line derived from peripheral leucocytes of a patient suffering from chronic myeloid leukaemia.

GeneID: 947 Human CD34

Swiss-port # P28906 Human Hematopoietic progenitor cell antigen CD34

Gene Symbol CD34
Gene Full Name CD34 molecule
Background CD34 protein may play a role in the attachment of stem cells to the bone marrow extracellular matrix or to stromal cells. This single-pass membrane protein is highly glycosylated and phosphorylated by protein kinase C. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2011]
Function CD34 is a possible adhesion molecule with a role in early hematopoiesis by mediating the attachment of stem cells to the bone marrow extracellular matrix or directly to stromal cells. Could 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. Presents carbohydrate ligands to selectins. [UniProt]
Research Area Cancer antibody; Cell Biology and Cellular Response antibody; Controls and Markers antibody; Developmental Biology antibody; Immune System antibody; Neuroscience antibody; Pro-B Cell Marker antibody; Endothelial Cell Marker antibody; Angiogenesis Study antibody
Calculated MW 41 kDa
PTM Highly glycosylated.
Phosphorylated on serine residues by PKC.
