Each full gene targeting project is split into the following phases:
1. TurboKnockout® gene targeting strategy design
2. TurboKnockout® targeting vector construction
3. Targeting in ES cells
4. TurboKnockout® mouse production
In conventional knockout models, one or more critical exons of the target gene are replaced with a drug-selection cassette. This results in the permanent inactivation of the target gene in all cells of the body throughout development.
In conditional knockout models, one or more critical exons of the target gene are flanked by LoxP sequences which can be recognized by Cre recombinase. By breeding these floxed mice (mice with gene locus flanked by LoxP) with tissue-specific Cre-expressing mice (Cre deleters), it is possible to specifically delete the floxed region and inactivate the gene in desired tissues, while in all other tissues, the target gene remains functional.
- Reporter knockin: A visually detectable marker gene (such as GFP or lacZ) is knocked into a gene locus to replace the coding sequence of the target gene for the purpose of monitoring the promoter activity of the gene. Alternatively, a marker or an epitope tag can be knocked into the end (or less frequently, the beginning) of the coding sequence to form a fusion protein, which allows target gene expression and localization/trafficking to be examined.
- Point mutation knockin: By introducing point mutation(s) into homology arms or the targeting vector, desired mutation(s) can be incorporated into the target gene. The mutated gene is expressed under the control of the wildtype gene regulatory elements.
- Humanized mouse: A humanized mouse is defined as a mouse model in which a portion or the full mouse gene sequence has been replaced by its human counterpart. The human gene is expressed under the control of the wildtype mouse regulatory sequences.
- ROSA26 knockin: ROSA26 is a locus that has been widely used for achieving global expression of the introduced gene in mice. The gene of interest is targeted into the first intron of this locus. The expression of the gene can be driven by the endogenous ROSA26 promoter or by a promoter of choice that is targeted into the locus along with the gene.
|Service||Price (Standard B6 strains)||Turnaround time|

(we will inject as many ES cell clones as needed to fulfill our guarantee)
|Optional: Breeding founders to obtain F1||Please inquire*|
* You can choose to receive F0 founder animals and perform their own breeding to F1 mice. To ensure the successful generation of F1 mice and germline transmission, breeding of F0 animals require adherence to Turboknockout® breeding protocol, which will be supplied to you. You can also choose to have Cyagen perform F1 breeding, which adds 1-3 months to the projected turnaround time. You can choose to breed F0 founders to wildtype mice or to other stains such as Cre deleter strains of your choice; additional service fees may apply.
Note: For special knockout/knockin services not listed above, please inquire about availability and pricing. The turnaround time above does not include the time for obtaining host institution’s approval for mouse importation and transit time during shipping.
Cyagen offers the best guarantee in the industry – we will fully refund the client’s service fee if animals with the specified genotype are not generated (except for genetic modifications severely affecting viability, morbidity, or fertility). Given the complexity of biological systems, a particular genetic modification may not result in the desired phenotype. As such, Cyagen's guarantee covers the creation of animals with the specified genotype, not a particular phenotypic outcome in terms of transcription, protein/RNA function, or organismal biology.
If you find another service provider that offers better pricing than ours, we will match the price plus an additional 5% off.
Standard payment terms include a 50% upfront payment before the project begins, and the remaining 50% plus shipping paid after completion of the project. If you need us to design your targeting strategy, we will provide this service for free irrespective of whether you end up choosing us for your project (other companies typically charge a few thousand dollars for this service).
We offer up to a 10% bulk discount for large orders. Large orders are defined as 5 or more projects from the same institution. If you bundle your orders with those of your colleagues, you can all qualify for the bulk discount.
Products are shipped from our facility in China to our Santa Clara, California facility, then are relayed to end users. For mouse shipments, the shipping charge includes courier cost plus a $100/crate handling fee. Cells are shipped on dry ice, and the charge includes courier cost plus a $45 handling fee. DNA constructs are shipped in E. coli at room temperature, and the charge includes courier cost plus a $10 handling fee. We typically use World Courier to ship live mice and FedEx for other shipments.
All animal work is conducted in our specific pathogen free (SPF) facilities that have been AAALAC accredited and OLAW assured. For details information, please visit our support section for Description of our Facility, Animal Health and Animal Welfare Program.
