GSM8067979: Dataset D10 lib2; Escherichia coli; RNA-Seq
Samples were fixed and processed according to the protocol of Blattman et al. (PMID: 32451472). Briefly, cells were fixed overnight with 4% formaldehyde, permeabilized with 50% ethanol followed by enzymatic cell wall digestion (100 µg/ml lysozyme, 15 min), then treated with DNase to remove genomic DNA. Reverse transcription and split-pool barcode ligation were carried out in situ in fixed cells according to the protocol of  Blattman et al. (PMID: 32451472). After barcoding, cells were separated into aliquots of ~20,000 cells for further processing. After lysis and reversal of crosslinking, second strand synthesis was performed using the NebNext Second Strand Synthesis module (New England Biolabs) and tagmentation was carried out using the EZ-Tn5 transposase (Lucigen), before final amplification with multiplex indexing primers.
