Background
The cluster of differentiation (CD) system is a glycosyl phosphatidylinositol anchored membrane protein thatbelongs to the CD38 family.It is generally used in immunophynotyping. CD157 was discovered in a bonemarrow stromal cell line where it facilitates pre-B-cell growth. CD157 is a bifunctional ectoenzyme that exhibitsboth ADP-ribosyl cyclase and cyclic ADP ribose hydrolase activities followed with CD38. It plays a role inrheumatoid arthritis (RA) due to its enhanced expression in RA-derived bone marrow stromal cell lines. Studieshave shown that this protein have a role in predicted to function as a cell surface receptor and animmunoregulatory molecule.

Usage guide
| Storage | Store at -20℃.Store the lyophilized protein at -20℃ to -80 ℃ up to 1 year from the date of receipt.
After reconstitution, the protein solution is stable at -20℃ for 3 months, at 2-8℃ for up to 1 week. |
|---|
| Reconstitution | Centrifuge the tube before opening. Reconstitute to a concentration of 0.1-0.5 mg/mL in sterile distilled water. Avoid vortex or vigorously pipetting the protein. For long term storage, it is recommended to add a carrier protein or stablizer (e.g. 0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose), and aliquot the reconstituted protein solution to minimize free-thaw cycles. |
