Cas9 Stable Cell Line - HeLa S3

The HeLa S3-Cas9 stable cell line is a versatile and high-performance gene model derived from the HeLa S3 cell line. The HeLa S3 cell line is a suspension-adapted clone of the original HeLa cervical adenocarcinoma cell line. The HeLa S3 cell line is characterized by its extremely rapid growth rate, high metabolic rate, and ability to grow in both adherent and suspension cultures. Like its parental HeLa cell line, it is HPV-18 positive and incorporates multiple copies of the viral genome into its genome. By integrating the Cas9 nuclease into this context, the HeLa S3-Cas9 cell line provides an exceptional platform for CRISPR-mediated gene editing, maximizing efficiency and scalability. Constitutive expression of Cas9 ensures the editing mechanism remains consistently available throughout the cell population, making this cell line ideal for high-throughput applications and the rapid construction of genetically modified cell populations.

The HeLa S3-Cas9 stable cell line has a wide range of applications, encompassing cell biology, functional genomics, and large-scale protein production. The HeLa S3-Cas9 cell line is the preferred host for whole-genome CRISPR screening, which aims to identify genes involved in important cellular processes such as the cell cycle, DNA repair, and intracellular transport. Researchers have also used this cell line to validate novel gene-editing tools and explore the molecular mechanisms of virus-host interactions. Its suspension growth capability makes it an ideal model for bioreactor-scale experiments and recombinant protein production, where Cas9 is used to optimize host cell metabolic pathways. Furthermore, the HeLa S3-Cas9 cell line is used in signal transduction and cancer progression research, providing a stable and easily manipulated background for elucidating the complex genetic mechanisms of human diseases.
