活性重组蛋白 Recombinant Human Eph receptor A3 / Hek; Cek4 / ETK1 / End3 / Hek4 / Mek4 / Tyro4 / Protein

EphA3 蛋白是一种受体酪氨酸激酶,与相邻细胞上的膜结合肝配蛋白家族配体混杂结合,启动接触依赖性双向信号传导。源自受体的下游途径称为正向信号传导,而肝配蛋白配体下游的途径称为反向信号传导。

生物活性

Measured by its binding ability in a functional ELISA. When Recombinant Human (rh) EphA3 is coated at 2 μg/mL (100 μL/well), the concentration of biotinylayed rhEphrin A5 Fc Chimera that produces 50% of the optimal binding response is found to be approximately 5-25 ng/mL.

70-
100 kDa


标签:
C-His


纯度:
>95% by SDS-PAGE.


内毒素:
<0.1EU/ug of the protein by LAL method.

Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4.Contact us for customized product form or formulation.


描述:
Recombinant Human Human Eph receptor A3 Protein is produced by 293F expression system. The target protein is expressed with sequence (Met1 - Gln541) of Human Human Eph receptor A3 (Accession P29320) fused with a C-His.


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。
