The isolation of human antibodies with naturally paired heavy and light chains is crucial for understanding the human antibody immune response. Here, we present a protocol for antibody cloning from the sorted single human memory B cells recognizing hepatitis B virus (HBV) S antigen (HBsAg). A two-fluorescent-dye labeling strategy against HBsAg allows for an improved sorting specificity, while non-relevant protein staining allows for the exclusion of non-specific B cells. This protocol could …
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
