GSM7852203: iPSC-derived GD2-CARTs, mRNA-derived cDNA; Homo sapiens; OTHER
1x10^6 sample cells were used 14 days after stimulation. Library was prepared using Chromium Single Cell 3ʹ v3.1 protocol (10x Genomics). Cellular mRNA and antibody-derived oligos were reverse-transcribed and indexed with a shared cellular barcode. Indexed cDNAs were then pooled and amplified by PCR according to the Chromium Single Cell 3' v3.1 protocol (10x Genomics) and with specific primers amplifying the antibody-derived tags. SPRI bead size selection was performed in order to separate both the mRNA-derived cDNA (>300bp) and the antibody-derived tagged cDNAs (180bp). For the mRNA derived cDNA library preparation, we further proceeded according to the manufacturer's instructions for Single Cell 3' v3.1 protocol (10x Genomics). -CITE-seq library: amplification was performed at 95°C for 3' followed by ten cycles at 95°C f¬¬or 20''; 60°C for 30''; 72°C for 20'' and final elongation 72°C for 5' with 5'-CAAGCAGAAGACGGCATACGAGATCGTGATGTGACTGGAGTTCCTTGGCACCCGAGAATTCCA-3' Small RNA RPI1 primer as i7 primer (Illumina).
