single cell transcriptomics and B-cell repertoire data from one vaccinated individual after Boostrix vaccination
The transcriptomics and BCR-rep data was meassured at the single-cell level from the longitudinal samples obtained from an individual following Boostrix vaccination. The donor had no known or suspected exposure to pertussis infection nor vaccination in the past 10 years. EDTA-blood samples for single-cell sequencing were collected at baseline and days 5 (d5), d7, d10 and d14 post-vaccination. At baseline, first 10,000 total CD19+ B cells were sorted, and after adjusting the sorting gate to exclusively sort PB/PCs, another 1,201 CD19+CD38++CD24+CD27+ PB/PCs were sorted. For subsequent visits, all available PB/PCs were sorted (11,051 cells). In total, we sorted 22,252 cells. Nearly 22,000 B cells enriched in PB/PCs from different time-points were processed into single cells in a Chromium Controller (10X Genomics). Reverse transcription PCR and library preparation were carried out under the Chromium Single Cell 3' v3 protocol (10X Genomics) per manufacturer's recommendations. After amplification of the cDNA, a 5 ´gene expression library and paired heavy and light chain library were generated from cDNA of the same cell using Chromium Single Cell VDJ reagent kit (scBCR-rep library; v1.1chemistry, 10X Genomics). After library preparation, quality control was performed using a bioanalyzer (Agilent 2100 Bioanalyzer; Agilent Technologies). The libraries were sequenced in the NovaSeq6000 sequencer (Illumina) using the v1.0 sequencing reagent kit (read length: 2 x 150bp). Overall design: Longitudinal examination of five different time points at baseline and post vaccination (baseline, days 5, 7, 10 and 14 post vaccination)
