PDF-Using a Recall Antigen Assay as a Tool for Understanding Immunity

While there is no industryaccepted protocol for measuring the functionality of peripheral blood mononuclear cells PBMC its an important test that should be conducted for quality control We needed a reliable reproducible way to measure the functionality of our cryopreserved PBMC so we developed a custom assay using recall antigens to understand the in vitro activity of our cells By testing PBMC for immune response to several different antigens over time we intended to better understand an acceptable range of variation in recall response from PBMC samples from the same donor over time Learn more at httpsastartebiocomresourcescasestudiesusingrecallantigenassaytoolunderstandingimmunity. .
