TurboKnockout® Technology for Knockin Mice

Explore our efficient TurboKnockout® process tailored for the precise delivery of knockin mouse models. Here's an outline of our workflow:

Stage	Description	Turnaround Time
Gene Targeting Strategy Design	Analyze target gene structure, adjacent genes, and existing models. Develop screening methods for targeted ES cells.	1-4 days
Targeting Vector Construction	Clone necessary DNA fragments into the targeting vector. Validate construction through sequencing and restriction digest.	6-8 weeks
Targeting in ES Cells	Electroporate TurboKnockout® ES cells, screen for targeted clones via PCR, and confirm by Southern blot and karyotyping.	8-14 weeks
Mouse Production	Introduce targeted ES cells into host embryos, transfer to surrogate mothers, and genotype founders. Breeding to F1 generation.	18-20 weeks

Note:

Turnaround times exclude institutional approval and shipping durations. For specific strain requests or larger knockin fragments, please inquire about custom solutions and pricing.
