| Abstract | OMIC-1 is a reference material (RM) designed for the development of SARS-CoV-2 BA.4/5 spike protein detection methods, as well as an antigen source for use in SARS-CoV-2 immunological assays. Reference values for the molar concentration, mass fraction, and mass concentration of spike protein in OMIC-1 have been established. Values are provided for the spike protein amino acid sequence only, and disregards the molar mass of the attached glycans. Information values for the size heterogeneity of the spike protein in OMIC-1 are provided. A unit of OMIC-1 contains 0.2 mL of SARS-CoV-2 BA.4/5 spike protein in Dulbecco's phosphate buffered saline (DPBS) with 10 mM HEPES sodium salt. |
