COVID-19 Convalescent Patient Antibody, RBD Affinity Purified
SARS-CoV-2 is the novel coronavirus that causes CoronaVirus Disease 2019 (COVID-19). This antibody preparation is affinity purified by immobilized recombinant receptor-binding domain (RBD) of the SARS-CoV-2 spike protein from Protein A/G purified IgG from pooled sera collected from convalescent COVID-19 patients. Serum was collected at least two weeks post symptom development from patients with positive COVID-19 PCR and serology tests. This antibody preparation is strongly positive in the Molecular Innovations SARS-CoV-2 IgG Seroconversion ELISA Kit and is useful as a positive control or calibrator in a variety of serological assays. Add deionized water to original volume, aliquot and freeze unused portion.
