CRY1/CRY2 double knockout cells
Multi-Component SwitchCRY1/CRY2 double knockout cells are human U-2 OS osteosarcoma cell models in which both cryptochrome genes were disrupted using duplex CRISPR/Cas9. The tool was generated by deleting whole exons with paired guide RNAs targeting exon-flanking intronic regions, producing a double-knockout circadian phenotype reported as arrhythmic.
