Background

CD34 is a 105-115 kDa member of the CD34/podocalyxin family of molecules. It is a sialomucin type glycoprotein, and presents carbohydrate to selectins during cell migration. CD34 is found on mast cells, eosinophils, vascular endothelial cells, stem cells and renal mesangial cells. Mature human CD34 is a 354 amino acid (aa) type I transmembrane protein (aa 32-385). It contains a 259 aa extracellular region (aa 35-287) with utilized N- and O-linked glycosylation sites, and a 74 aa cytoplasmic domain that may undergo Tyr phosphorylation. There is one splice variant that shows a four aa substitution for aa 325-385. Human CD34 can undergo membrane cleavage by bacterial proteases to generate 30-40 kDa soluble fragments. And notably, desialylated CD34 shows a 40 kDa increase in MW (to 150 kDa) when run in SDS-PAGE. Over aa 32-290, human CD34 shares 56% aa identity with mouse CD34.

FAQs for CD34 Antibody (AF7227X). (Showing 1 - 1 of 1 FAQ).

1. I wonder if you have a CD105 or CD34 antibody suitable for IHC that is specific for human and do not bind mouse?
   • We do not have any anti-human CD34 or CD105 antibodies that are confirmed to NOT detect the mouse protein. When we have tested an antibody and confirmed that it will not react with mouse samples, we will add Mu(-) to the datasheet, and unfortunately all of our CD105 and CD34 antibodies will either detect the mouse protein, or they have not been used in mouse samples before.
