Single Cell Omics core policies
Users are responsible for supplying tissues, dissecting tissue, and optimizing cell dissociations or nuclear preparations. High quality cell preparations are key to obtaining quality data. The core is not responsible for failed data because of poor cell preparations.
Users are required to purchase reagent kits suitable to their needs. For example, 10X Genomics reagents for one scRNA-seq, scATAC-seq or snRNA-seq library costs about $1700. Reagents for one combined multi-omic scRNA/ATAC-seq library is about $3100. There are also costs for Ilumina library preparation kits and sequencing that must be covered by users. Library generation takes about 2 days, but the bioinformatic analysis can take weeks.
Co-authorship is expected when significant intellectual expertise and consultation has been provided or percent effort for bioinformatic analyses has been provided to generate data that appears in manuscripts.
Fees are intended to cover costs including pipette tips, Spry beads, service contracts for equipment, etc.
