Source
Anti-SARS-CoV-2 Spike RBD Antibody, Human IgG1 (AS113) (Omicron Specific) is a chimeric monoclonal antibody recombinantly expressed from HEK293 cells, which combines the variable region of a mouse monoclonal antibody with human IgG1 constant domain. The mouse monoclonal antibody is produced from a hybridoma resulting from fusion of SP2/0 myeloma and B-lymphocytes obtained from a mouse immunized with omicron Spike RBD. The antibody is specific against the Omicron (B.1.1.529/BA.1) variant of SARS-CoV-2, and has no binding with the spike RBD of the wild type virus and other viral lineages.

I used this antibody as a control for flow cytometry and it was very reliable. A clear peak shift could be seen with this antibody. When we had questions about what SARS-CoV-2 variants this mAb bound to, ACRO replied quickly and gave us information on the variants we inquired about and then some. ACRO is a company I would purchase from again and my company has used them consistently.

This omicron protein is a really great product and is high quality. The protein came on time to conduct our experiments and we were able to produce satisfactory results from using this protein. The protein was shipped with dry ice and was in a secure package. We would highly recommend this company and this protein to other labs that are doing omicron research.
