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.
