Seroconversion Panels

Access Biologicals is now offering Seroconversion panels
Home » Access Biologicals Panels » Seroconversion Panels

Our seroconversion panels are intended for use by diagnostic manufacturers and researchers during assay development, evaluation and troubleshooting test methods.  Each sample is a unique plasma sample drawn during a developing virus or infection.

 

COVID-19 Seroconversion Panels

The COVID-19 Seroconversion Panel consists of 14 members with each member containing 1 vial of 1.0 mL of human plasma. Panel members collected in this longitudinal series are from a single donor during the progression of a SARS-CoV-2 infection. This panel illustrates the onset and decline of IgM, IgG and Ig total SARS-CoV-2 virus antibody titers over a period of 87 days. Panel members are undiluted, naturally occurring plasma samples collected in 4% sodium citrate. Units were aseptically filtered. No preservative has been added. All panel members are ready to use.

 

 

 

Commercial COVID-19 serial seroconversion panel for validation of SARS-CoV-2 antibody assays

In this study, a seroconversion panel obtained from a single patient was tested against three commercially available test kits for detecting anti-SARS-CoV-2 antibodies. This seroconversion panel is one of the first available for SARS- CoV-2. The advantage of this characterized seroconversion panel is the expansive time period (samples taken over almost 90 days) providing an extensive record of seroconversion in this single donor.
