title: GSM7599060: 7dpci 2; Danio rerio; RNA-Seq
library_construction_protocol: Single cells of border zone zebrafish cardiomyocytes were FACS sorted based on nppa:mCitrine levels at 1, 3 and 7 dpci into 384well plates Unfixed ventricles were dissociated by Collagenase and TrypLE Express treatment to prepare single cell solutions. Cells were subsequently FACS sorted based on nppa:mCitrine or myl7:GFP expression in 384 well plates, each well containing 1 cell, containing Vapor-Lock oil with CEL-Seq2 barcoded primers, spike-in mRNA and dNTPs (Single Cell Discoveries). Plates were spun down and frozen at -80oC until ready for library prep. Plates were processed by Single Cell Discoveries using the SORT-seq protocol. In this protocol, the CEL-seq2 protocol is carried out with the aid of robotic liquid handlers. Illumina sequencing libraries were prepared with the TruSeq small RNA primers (Illumina) and paired-end sequenced at 75 bp read length on the Illumina NextSeq platform.
