纯度:> 80 % as determined by SDS-PAGE.
内毒素:< 1.0 EU per μg protein as determined by the LAL method.
生物活性:Testing in progress
蛋白构建:A DNA sequence encoding the SARS-CoV-2 (2019-nCoV) Spike Protein (S2 ECD) (Ser686-Pro1213) was expressed with a polyhistidine tag at the C-terminus. The purified protein was biotinylated in vitro.
表达宿主:Baculovirus-Insect Cells
种属:SARS-CoV-2
预测 N 端:Ser 686
分子量:The recombinant SARS-CoV-2 (2019-nCoV) Spike Protein (S2 ECD, His tag) consists of 539 amino acids and predicts a molecular mass of 59.37 kDa.
缓冲液:Lyophilized from sterile PBS (containing 300 mM NaCl).
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.
