Single-cell V(D)J-seq of CD3+ and CD19+ lymphocytes from PBMCs of COVID-19 patients

We selected COVID-19 positive individuals, their direct contacts, and unmatched controls. CD3+ and CD19+ cells were sorted from PBMCs and they were analyzed for surface expression, 5' gene expression, and TCR/BCR profiling at single-cell resolution. For each group, three samples were pooled using Biolegend hashtag antibodies (TotalSeq™-C C0251, TotalSeq™-C C0252, and TotalSeq™-C C0253 ) and multiple runs were performed per library. The raw data for each run will be provided upon request.
