Seroconversion Panels – COMING SOON

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.


Hepatitis A (HAV) Seroconversion Panels

Our Hepatitis A (HAV) seroconversion panels consists of either 13 or 23 members with each member containing 1 vial of 1.5 mL of human plasma. Panel members collected in this longitudinal series are from a single donor during the progression of an early HAV infection. This panel illustrates the onset and decline of IgM and Ig total Hepatitis A virus antibodies and RNA titer over a period of 108, 122 or 140 days. Panel members are undiluted, naturally occurring plasma samples. Units were aseptically filtered. No preservatives have been added. All panel members are ready to use.
