Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.
描述
Recombinant Human KLRG1/CLEC15A/CD369 Protein is produced by HEK293 cells expression system. The target protein is expressed with sequence (Leu60-Phe195) of human KLRG1/CLEC15A/CD369 (Accession #NP_001316028.1) fused with a raFc tag at the N-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 vial 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。
请在蛋白复溶计算器中输入蛋白总质量和所需终浓度,快速计算您需要添加溶液的体积吧!
KLRG1 (killer cell lectin?like receptor G1), also called MAFA (mast cell function associated), is an inhibitory type II transmembrane glycoprotein of the C?type lectin family, designated CLEC15A.Within the ECD, Human KLRG1 shares 57% and 80% aa sequence identity with mouse and rat KLRG1, respectively.KLRG1 is expressed on subpopulations of CD8+, CD4+, regulatory, and gamma/delta T cells as well as on NK cells. KLRG1 is expressed on T cells found in cord blood, but it is down?regulated postnatally and is subsequently re?expressed on antigen?exposed T cells. It is expressed by a greater proportion of CD8+ T cells in the elderly and by virus?specific CD8+ T cells during chronic virus infection. KLRG1 binds to E-, N-, and R-Cadherins, triggering ITIM?dependent KLRG1 signaling and inhibition of T cell activation. The response is bi?directional, as KLRG1 binding to E?Cadherin on dendritic cells (DC) can induce an anti?inflammatory DC phenotype (increased IL?10 production and decreased IL?6 and TNF? alpha production).
