种属:

Human

 

表达宿主:

293F

 

表达区间:

Ala33-Glu407

 

实际分子量:

115-125 kDa

 

标签:

C-hFc&His tag

 

纯度:

>95% by SDS-PAGE.

 

内毒素:

0.1EU/ug of the protein by LAL method.

 

制剂:

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 TrkA Protein is produced by 293F expression system. The target protein is expressed with sequence (Ala33-Glu407) of Human Human TrkA (Accession P04629) fused with a C-hFc&His tag.

 

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-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-80°C,随取随用,避免反复冻融。
