Here, we detail a protocol to identify an antigen-specific B cell population using SpyCage reagents tailored to bind MSP1-19 antigen in a rodent malaria model. We describe steps for the preparation of splenic single-cell suspension, B cell enrichment, and staining to facilitate sorting of live cells for downstream applications such as single-cell RNA, V(D)J, and assay for transposase-accessible chromatin (ATAC) sequencing. For complete details on the use and execution of this protocol, please refer to Calôba et al.1.
