描述

Recombinant Human BST-1/CD157 Protein is produced by Human Cells expression system. The target protein is expressed with sequence (Gly29-Lys292) of human CD157/BST1/ADP-ribosyl cyclase 2/Cyclic ADP-ribose hydrolase 2 (Accession #Q10588) fused with a 6×His tag at the C-terminus.

储存

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.未开盖的干粉蛋白在 -20°C至-80°C可保存12个月；
复溶之后，蛋白溶液在-20°C及以下可保存3个月，在2-8℃可保存1周。

复溶

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.收到重组蛋白产品之后请检查蛋白冻干粉末是否贴于瓶底，如果粉末浮起，开盖之前请先低温离心。将蛋白用说明书中指定的缓冲液复溶至0.1-0.5 mg/mL（请注意蛋白复溶浓度不能低于0.1 mg/mL），室温平衡5-10 min保证充分溶解，复溶过程中请不要剧烈涡旋及吹打蛋白溶液。如需长期储存，建议复溶时添加载体蛋白或者稳定剂（如0.1% BSA, 5% HSA, 10% FBS 或者 5% 海藻糖），同时将复溶后的蛋白溶液按照需求进行分装，储存于-20°C至-80°C，随取随用，避免反复冻融。

背景信息

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.
