种属
Human
表达宿主
HEK293 cells
描述
Active Recombinant Human BTLA Protein is produced by HEK293 expression system. The target protein is expressed with sequence (Lys31-Thr134) of human BTLA (Accession #NP_001078826.1.) fused with an Fc, 6×His tag at the C-terminus.
标签
C-hFc&His
纯度
> 90% by SDS-PAGE.
内毒素
< 0.1 EU/μg of the protein by LAL method.
生物活性
Measured by its binding ability in a functional ELISA. Immobilized Recombinant human BTLA at 3 μg/mL (100 μL/well) can bind Biotinylated Recombinant human HVEM with a linear range of 18-72 ng/mL.
制剂
Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.Contact us for customized product form or formulation.
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 vial 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。

研究方向

BTLA/CD272 是淋巴细胞上表达的抑制性受体,通过与酪氨酸磷酸酶 PTPN6/SHP-1 和 PTPN11/SHP-2 相互作用,充当抗原受体信号传导的负调节因子。这些相互作用有助于调节免疫反应和维持淋巴细胞稳态。BTLA 可能与 TNFRSF14 发生顺式和反式相互作用,顺式相互作用在幼稚 T 细胞中发挥调节作用,抑制反式相互作用以维持静息状态。相比之下,在适应性免疫反应期间占主导地位的反式相互作用为效应 T 细胞提供生存信号。BTLA 与其结合伙伴之间错综复杂的相互作用强调了其在免疫调节中的多方面作用。
