This cell line is a clonal derivative from the Cas9-Expressing HCT116 Cell Pool (Biohippo, #78073). It was generated by limited dilution of the original pool and isolation of individual clones, which were screened based on Cas9 expression to obtain a high-expressing cell line. The expressed Cas9 protein includes a C-terminal FLAG tag.
Mycoplasma testing: This cell line has been screened using the MycoAlert Mycoplasma Detection Kit (Lonza, #LT07-118) to confirm the absence of Mycoplasma contamination. MycoAlert Assay Control Set (Lonza, #LT07-518) was used as a positive control.
Host Species: human
Supplied as Each vial contains ~2 x 10^6 cells in 1 ml of FBS with 10% DMSO.
Background
Cas9 (Streptococcus pyogenes CRISPR associated protein 9) is an endonuclease enzyme that, when recruited to a specific DNA sequence by the sgRNA (single guide RNA), introduces a double stranded break into the DNA. This double stranded break is repaired in mammalian cells either through Non-Homologous End Joining or Homologous Recombination. Non-Homologous End Joining often results in the deletion or insertion of several base pairs at the cut site, which, when resulting in a frameshift, causes the functional inactivation of the targeted gene. Cas9-expressing HCT116 cell lines can be transduced or electroporated with sgRNA targeting a gene of interest to quickly generate knock-out cell pools or cell lines.
Application
1. Quickly generating knock-out cell pools or cell lines in HCT116 cells. 2. Implementing sgRNA screens in Cas9-expressing HCT116 cells.
