Mouse Model Strategies & Allele Types

Safe Harbor Locus

A defined region of the genome where a transgene or targeted DNA sequence can be inserted without disrupting endogenous genes or regulatory networks. Integration at a safe harbor site allows stable, predictable expression.

Overview

A safe harbor locus is a defined region of the genome where a transgene or targeted DNA sequence can be inserted without disrupting endogenous genes or regulatory networks. Integration at a safe harbor site allows stable, predictable expression of the introduced construct while maintaining overall genomic integrity.

Frequently Asked Questions

What makes a locus a 'safe harbor'?

Safe harbor loci are characterized by transcriptional accessibility, genomic stability across generations, and neutrality with respect to nearby gene regulation.

Rosa26 Locus

A well-characterized safe harbor site in the mouse genome, located on chromosome 6. It supports stable and ubiquitous expression of inserted genes without interfering with nearby genomic functions and is the standard integration site for transgenic constructs.

Single-Copy Integration

The precise insertion of a single copy of a DNA construct into a defined location within the genome. This approach prevents the variability, gene silencing, and expression artifacts associated with random multi-copy insertions.

Safe-Harbor Targeted Transgenesis

A precise genome engineering strategy in which a transgene is inserted into a well-characterized, transcriptionally active, and non-disruptive genomic locus to ensure predictable and stable expression.
