Neutrophils were depleted and B cells were enriched from PBMC samples using CD66b-biotin antibodies and the B cell enrichment kit (Miltenyi Biotech). Enriched B cells were lysed in Lysis Buffer (10 mM Tris-HCl, 10 mM NaCl, 3 mM MgCl2, 0.1% Tween-20, 0.1% NP-40, 0.01% digitonin, 1% BSA, 1 mM DTT and 1 U/μl RNase inhibitor in nuclease-free water) for three minutes on ice. Lysed nuclei were washed three times in Wash Buffer (10 mM Tris-HCl, 10 mM NaCl, 3 mM MgCl2, 1% BSA, 0.1% Tween-20, 1 mM DTT and 1 U/μl RNase inhibitor in nuclease-free water) before loaded onto the Chromium Next GEM Chip J. Gene expression and ATAC libraries were prepared according to manufacturer’s guidelines and sequenced on Nextseq 2000 (Illumina).</sample_protocol><sample_protocol>Sample Collection - Briefly, cryopreserved PBMCs were thawed in RPMI with 10% FBS and resuspended in 1X red blood cell lysis solution (Miltenyi Biotech) to lyse residual red blood cells.
