Rose26 Kockin Mouse Model

Safe Harbor locus knock-in enables fast and site-specific insertion of genes into an intergenic, transcriptionally active locus such as the well-defined mouse Rosa26 and Hipp11 (H11) loci. It permits the insertion of large transgenes more efficiently than at a specific genetic locus and overcomes problems associated with random insertion such as disruption of the host genome and gene silencing. Safe harbor locus knock-in mouse models are ideal for gene overexpression, gene knockdown, humanized gene knockin, inducible gene expression, and other applications. Applied StemCell’s has a thorough understanding of safe harbor knock-in (Rosa 26, H11, others) with CRISPR, for a fast, site-specific knock-in mouse model generation, including large transgene insertion.
