Frozen Sperm + KO/cKO Mouse
Breeding Package
Order research-ready mice with your specified genotype directly from Cyagen's cryopreserved sperm bank — no live colony to maintain, no genotyping to manage. Genotype and headcount are guaranteed for every cataloged model.

Promotional pricing for Singapore
Applies to models already validated and stocked in Cyagen's cryopreserved sperm bank. Prices exclude shipping. Models still in development add ~2 months to the listed TAT. Limited-time offer — Aug 12 to Nov 1, 2026.
[flox/flox,Cre] mice carry both the floxed allele and Cre recombinase — ready for immediate experiments upon delivery. All models are on pure C57BL/6 background. Packages ship with Cyagen's standard Cre line for the target; requests for an alternate Cre line are quoted separately.
Featured cKO Packages — Two Delivery Options
Both packages include [flox/flox,Cre] and [flox/flox] mice, available in standard or expedited delivery
Three reasons to choose our sperm bank
No need to maintain live colonies. No genotyping headaches. Just tell us your gene — we deliver the mice.
Timelines and deliverables above apply to models already in the sperm bank; custom or in-development models are evaluated case by case.
How IVF saves you 3+ months
IVF-based rapid expansion shortens breeding timelines while improving consistency.
Large-Scale Production
Obtain large numbers of next-generation mice in a fraction of the time required for natural breeding.
Save 3+ Months
One generation: 3 months (natural) → 1.5 months (IVF). Females ready at 4 weeks instead of 6.
Consistent Data
Age-matched litters from simultaneous IVF reduce experimental variability.
Reliable for Difficult Lines
For males that cannot breed naturally, IVF provides a viable alternative.

How the program works
From gene search to delivered mice, in five tracked steps.
Program scope, in plain terms
What this campaign covers — and where pricing or timelines can vary.
01What's Covered
Promotional pricing applies to KO/cKO models already validated and stocked in Cyagen's sperm bank. Custom model generation for genes outside the repository is quoted separately.
02Timeline Guarantee
Listed TAT applies to catalog-ready models. Genes still under development add roughly 2 months to the listed timeline — our team will confirm the exact date before you order.
03What's Included
Prices cover breeding, IVF, and PCR genotyping through to your specified genotype and headcount. Shipping and import logistics are quoted separately based on destination.
04Cre Line Requests
cKO packages ship with Cyagen's standard Cre line for the target gene. Requests for an alternate or additional Cre line are evaluated and priced on inquiry.
Frequently asked questions
What if my gene isn't in the sperm bank yet?
Search your gene in the tool above first. If it isn't yet in our 18,000+ model repository, our team can evaluate custom KO/cKO model generation and provide a separate quote and timeline — this campaign's pricing applies only to catalog-ready models.
Is the exact genotype and quantity guaranteed?
Yes, for models in the sperm bank — Cyagen guarantees delivery of the specified genotype and headcount for cataloged strains. PCR genotyping is performed at every generation to confirm this before shipment.
Can I request faster delivery than the standard TAT?
Fast-track delivery is available for the featured cKO packages (see the Campaign Pricing section above). For other packages, contact our Singapore team to check whether expedited breeding is feasible for your gene.
Does the price include shipping to my institution?
No — listed prices cover breeding, IVF, and genotyping only. Shipping and any import/customs logistics are quoted separately based on your delivery address.
When does the delivery timeline start?
The TAT clock starts once your order is confirmed and payment is received, not from your initial inquiry. Our team will confirm the projected delivery date in writing before you pay.
