COVID-19 Antibody & Antigen Titer Assay Kits

Critical reagents for COVID-19 vaccine development and evaluation

This series of high quality antibody and antigen titer assay kits can be used for COVID-19 vaccine development and evaluation, as well as determining SARS-CoV-2 viral infection. The assay kits provide excellent performance, having been developed using high quality proteins with high specificity, sensitivity and reproducibility. Currently, we provide kits for IgG/M antibody detection, neutralizing antibody detection, and nucleocapsid protein antigen titer detection. These COVID-19 antibody and antigen assay kits form part of our broader Coronavirus and COVID-19 research portfolio, offering recombinant proteins, pseudotyped lentivirus, antibodies for diagnostic kit development, and more.

IgG Antibody Titer Detection

This CE certified serologic test assay kit enables rapid detection of Anti-SARS-CoV-2 antibodies in serum or plasma by SARS-CoV-2 Spike protein RBD. It employs a standard indirect ELISA format, suitable for use in characterizing antibodies produced in response to SARS-CoV-2 infection.
