title: BCR repertoire
design: Total RNA from cells was amplified for clone-specific rearrangements of the Ig heavy chain genes using the Long Read iR-Reagent System (iRepertoire, Huntsville, AL, USA) at LAS (Life is Art of Science) Laboratory (Gimpo-si, Korea). The library indices were used for each cell:  pB-1a (MBHI1, GTGTCA), FO B (MBHI2, TCTGAC), CD80high MZ B (MBHI3, TGACTA), and CD80low MZ B (MBHI4, CGCTCT).
