储存
Store the lyophilized protein at -20°C to -80°C for long term.
After reconstitution, the protein solution is stable at -20°C for 3 months, at 2-8°C 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 votex 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。
蛋白复溶计算器
CD161 蛋白在抑制自然杀伤 (NK) 细胞的细胞毒性中发挥着至关重要的作用。激活后,CD161 会刺激特定的酸性鞘磷脂酶/SMPD1,导致细胞内神经酰胺水平显着增加。激活过程还会刺激 AKT1/PKB 和 RPS6KA1/RSK1 激酶,并显着增强抗 CD3 诱导的 T 细胞增殖。作为凝集素,CD161 与末端碳水化合物 Gal-alpha(1,3)Gal 表位和 N-乙酰基乳糖胺表位结合。此外,它还充当 CLEC2D/LLT1 的配体,抑制 NK 细胞介导的细胞毒性和靶细胞中的干扰素 γ 分泌。CD161 作为具有二硫键的同型二聚体存在,与酸性鞘磷脂酶/SMPD1 相互作用,有助于其在免疫反应中的多方面调节功能。
研究方向
CD161 (NKRP1) is a lectin-like receptor present on NK cells and rare T-cell subsets. We have observed CD161 expression in some cases of T-cell prolymphocytic leukemia (T-PLL) and found it to be useful in follow-up and detection of disease after treatment.
