S1 protein NTD: A promising target for therapeutic mAbs against COVID-19

On June 22th, an article A neutralizing human antibody binds to the N-terminal domain of the Spike protein of SARS-CoV-2 1 was published on Science. Researchers pointed out the NTD as a promising target for therapeutic mAbs against COVID-19.

 

ACROBiosystems developed SARS-CoV-2 S1 protein NTD (Cat. No. S1D-C52H6) and corresponding anti-SARS-CoV-2 Spike NTD antibody (Cat. No. SPD-M121). The bioactivities of S1 protein NTD and anti-SARS-CoV-2 Spike NTD antibody were verified by ELISA, BLI and SPR. SARS-CoV-2 S1 protein NTD could be used in animal immunization, macromolecular drug and antibody development, etc.
