纯度:> 90 % as determined by SDS-PAGE
内毒素:< 1.0 EU per μg of the protein as determined by the LAL method
生物活性:Testing in progress
蛋白构建:A DNA sequence encoding the human coronavirus HKU1 (isolate N1) (HCoV-HKU1) spike protein (S1 Subunit) (YP_173238.1) (Met 1-Arg 760) was expressed with a polyhistidine tag at the C-terminus.
NP No.:YP_173238.1
表达宿主:HEK293 Cells
种属:HCoV-HKU1
预测 N 端:Gly 16
分子量:The recombinant human coronavirus HKU1 (isolate N1) (HCoV-HKU1) spike protein (S1 Subunit, His Tag) consists of 756 amino acids with a predicted molecular mass of 85.8 kDa. As a result of high glycosylation, the apparent molecular mass of the recombinant protein is approximately 130-140 kDa in SDS-PAGE under reducing conditions.
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.
