Yurogen has successfully developed rabbit monoclonal antibodies against an important inflammasome component that work in Immunohistochemistry (IHC) for one of Yurogen’s big pharma clients, utilizing Yurogen’s SMab™ platform. As many antibodies that work in Western blot (WB) tend to work in IHC as well, high-throughput automated WB was introduced in the early stage (B cell culture supernatants) to identify potential antibody clones suitable for IHC. A total of 192 ELISA-positive B cell culture supernatants from 1920 sorted B cells were screened against inflammasome component-expressing wild-type or knockout cell lines. The best candidates were then selected for rabbit IgG gene cloning and recombinant expression. IHC staining using the recombinant antibodies on wild-type and knockout cell lines was then conducted. Many clones that worked in WB also performed well in IHC.
