B cells undergo a process of somatic recombination leading to the synthesis of a staggering diversity of transmembrane and secreted antibodies. This process dates back to the evolution of jawed vertebrates and is pivotal to the origin of lymphocyte-based adaptive immune responses. Here, we optimized a sequencing-based protocol to characterize B-cell-specific IgH transcripts from bulk RNA in the African turquoise killifish, an emerging model organism characterized by naturally short life span and by a vast range of age-dependent dysfunctions.
