"Quick Knock-In"™ Technology: The Fast & Safe Way

"Quick Knock-In"™ Technology:
Guaranteed Knock-in mouse line in less than 22 weeks

DNA microinjection has been intensively used for:
Tissue-specific and inducible overexpression
In vivo studies of dominant isoforms
Promoter analysis: response elements, activators, etc.
In vivo studies of pathways or cell responses using reporter genes
But DNA microinjection has limited potential due to random integration: position effects, etc.
Knock-in (targeted insertion) approach overcomes DNA micro-injection limits
More than 450 publications (PubMed) have demonstrated that targeted insertion provides:
A more predictable expression pattern than does random integration (transgenic)
A unique and fully characterised integration site enabling in vivo analysis on a single mouse line.
But each model requires a new targeting vector (2 to 6 months) and suffers from uncertainty of gene targeting.
HPRT locus enables ubiquituous and tissue-specific expression
More than 50 publications (PubMed) have demonstrated that HPRT locus enables ubiquitous and tissue-specific expression.
