title: GSM4041440: scRNA-Seq Responder; Mus musculus; RNA-Seq
library_construction_protocol: Tumors were excised and CD45+ immune cells were isolated by FACS, and submitted for single cell RNAseq analysis. Cells were processed using the 10X Genomics Chromium Controller with the Single Cell 3ʹ v3 Reagent Kit, according to manufacturer's directions. Briefly, a target number of cells per library was roughly achieved by loading 1.6 times the target number of cells in suspension, along with barcoded beads and partitioning oil, into the Chromium Controller, in order to create GEMs (Gel Beads in Emulsion). The Chromium Controller combines individual cells, first strand master mix, and gel beads (GEMs) containing barcoded oligonucleotides into single-cell droplets for first strand cDNA synthesis, so that each cell is marked with its own unique barcode during reverse transcription. After first strand synthesis is complete, the emulsion is dissolved and the cDNA is pooled for bulk processing as a single sample. The sample is fragmented, end-repaired, A-tailed and ligated with universal adapters. A second sample barcode is then added during the PCR step, allowing for unique library identification. The end result is a single library representing one cell suspension, containing data for each individual cell.
