The Genentech Cell Line Screening Initiative (gCSI)


The Genentech Cell Line Screening Initiative (gCSI) was undertaken independently of CCLE and GDSC to to address the concerns of inconsistencies across large-scale pharmacogenomic studies. In gCSI, Genentech independently characterized the response of 410 cancer cell lines to a subset ‚Äčagents tested by GDSC and CCLE. Genentech also evaluated three specific aspects of the screening protocols that are relevant to measured drug response: readout of cell viability (metabolic versus DNA content), seeding density strategy, and cell culture media conditions.
