Source : Escherichia Coli. PRAP1 Human Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain (a.a 21-151) containing 141 amino acids including a 10 a.a N-terminal His tag. The total molecular mass is 16.2kDa (calculated). Proline-rich acidic protein 1 (PRAP1) is essential for maintaining homeostasis in epithelial cells e.g. in liver or gastrointestinal tract. PRAP1 is abundantly expressed in the epithelial cells of the liver, kidney, gastrointestinal tract and cervix. PRAP1 is notably down-regulated in hepatocellular carcinoma and right colon adenocarcinoma compared with the respective adjacent normal tissues.
It is recommended to add 200µl deionized water to prepare a working stock solution of approximately 0.5mg/ml and let the lyophilized pellet dissolve completely. PRAP1 is not sterile! Please filter the product by an appropriate sterile filter before using it in the cell culture.
