title: GSM5215503: cochlear duct P1; Rattus norvegicus; RNA-Seq
library_construction_protocol: The cochlear duct tissues were placed in a sterile RNase-free culture dish containing an appropriate amount of calcium-free and magnesium-free 1 × PBS on ice, the tissues were transferred into the culture dish and cut it into 0.5 mm2 pieces, the tissues were washed with 1 × PBS, and remove as many non-purpose tissues as possible such as blood stains and fatty layers. Tissues were dissociated into single cells in dissociation solution (0.35% collagenase IV5,2 mg/ml papain, 120 Units/ml DNase I) Single-cell suspensions were loaded to 10x Chromium to capture 5000 single cells according to the manufacturer's instructions of the 10X Genomics Chromium Single-Cell 3' kit (V3). The following cDNA amplification and library construction steps were performed according to the standard protocol. Libraries were sequenced on an Illumina NovaSeq 6000 sequencing system (paired-end multiplexing run,150bp) by LC-Bio Technology co.ltd., (HangZhou, China) at a minimum depth of 20,000 reads per cell.
