Innovative Research Inc Single Donor Human SARS-Cov-2 Negative Serum 100ul
Single Donor Human SARS-Cov-2 Negative Serum from Innovative Research is a whole blood derived product. Samples were collected from presumptive negative donors prior to December 2019, and COVID-19 negative status has been confirmed via SARS-CoV-2 IgG antibody assay. This serum is suitable for use as a negative control and to confirm serological assay results, among other research applications. This product has not been tested directly for the presence of any other viruses, and out of an abundance of caution it is recommended to handle as if capable of spreading infectious disease.
