Product Description |
Recombinant Human CD38 Protein is expressed from HEK293 with His tag at the C-Terminus.It contains Val43-Ile300. |
Product Background |
CD38 (cluster of differentiation 38), also known as cyclic ADP ribose hydrolase, is a transmembrane glycoprotein found on the surface of some immune cells including plasma cells, activated or immature T and B cells, monocytes, and natural killer cells. CD38 participates in cell adhesion, signal transduction and calcium signaling. |
