蛋白构建:A DNA sequence encoding the SARS-CoV-2 (2019-nCoV) Spike S1 NTD (Met1-Ser305) was expressed with a c-terminal Fc region of human IgG1 tagged AVI tag at the C-terminus. The purified protein was biotinylated in vitro.
预测 N 端:Val16
分子量:The recombinant SARS-CoV-2 (2019-nCoV) Spike S1 NTD consists of 546 amino acids and predicts a molecular mass of 61.74 kDa.
缓冲液:Lyophilized from sterile PBS, pH 7.4
Please contact us for any concerns or special requirements.
Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
Please refer to the specific buffer information in the hard copy of CoA.
运输方式:In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
稳定性 & 储存条件:Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃
Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
复溶:A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.
