This protein carries a polyhistidine tag at the C-terminus.
The protein has a calculated MW of 26.6 kDa. The protein migrates as 33-35 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
>95% as determined by SDS-PAGE.
>90% as determined by SEC-MALS.
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.

SARS-CoV-2 S protein RBD (N501Y), His Tag on SDS-PAGE under reducing (R) condition. The gel was stained with Coomassie Blue. The purity of the protein is greater than 95%.
The purity of SARS-CoV-2 S protein RBD (N501Y), His Tag (Cat. No. SPD-C52Hn) is more than 90% and the molecular weight of this protein is around 28-38 kDa verified by SEC-MALS.
Serial dilutions of Monoclonal Anti-SARS-CoV-2 RBD Potent Neutralizing Antibody, Human IgG1 (Cat. No. SPD-M180) were added into SARS-CoV-2 S protein RBD (N501Y), His Tag (Cat. No. SPD-C52H) : Biotinylated Human ACE2, His,Avitag (Cat. No. AC2-H82E6) binding reactions. The half maximal inhibitory concentration (IC50) is 1.13169 (Routinely tested).
Human ACE2, Fc Tag (Cat. No. AC2-H5257) captured on CM5 chip via Anti-human IgG Fc antibodies surface can bind SARS-CoV-2 S protein RBD (N501Y), His Tag (Cat. No. SPD-C52Hn) with an affinity constant of 1.24 nM as determined in a SPR assay (Biacore 8K) (Routinely tested).
