PBMCs from C57BL/6 mice (v1, 150x150)

Mouse peripheral blood mononuclear cells (PBMCs) pooled from C57BL/6 mice were obtained from C&M LabPro (part number 11121911). The cells were 84% viable (trypan blue stain).

Amplified cDNA was used to generate TCR and Ig enriched libraries, following the Chromium Single Cell V(D)J Reagent Kits User Guide with Feature Barcode technology for Cell Surface Protein (CG000186).

The libraries were sequenced on an Illumina NovaSeq 6000 (NovaSeq software v1.6).

Note: The web summary will have a Warning alert for TCR library. This is due to the low fraction of T cells in mouse PBMC and the low expression levels of TCR-α and TCR-β genes in these cells.
