EZcohort® Models

Lab tech working with cryopreservation materialsObtaining the right genetically engineered models (GEMs) in a simple, fast, and transparent way is essential to drive your research program forward, yet accessing cryopreserved lines can be cumbersome. To provide customers with valuable animal models without the burden of lengthy legal negotiations and undefined deliverables Taconic Biosciences has created the EZcohort® models collection to ensure easy access to a select group of GEMs. EZcohort® models are distributed under clear terms of use and include rights to use, breed, and crossbreed. The granted use rights are perpetual.

Easy access means starting your project sooner

EZcohort® models are distributed under simple terms of sale that grant the purchaser rights to use, breed and crossbreed. The full Terms of Sale are located below and on every EZcohort® model page by clicking on the 'Licensing' accordion. Models are sold under terms which grant perpetual use rights.

  • What are EZcohort® models?
    EZcohort® models are a collection of Taconic's cryopreserved, genetically engineered models.

  • Why is it called "EZcohort®"?
    Taconic has made it easy for researchers to access these models through the use of simple terms of sale and predefined cohort sizes.

  • Can I just place an order and receive the model?
    Yes. Submit your order by emailing the signed terms of sale along with a purchase order to legal@taconic.com.

  • Are EZcohort® models cryopreserved?
    Yes. Cryorecovery generally takes 14-16 weeks.

  • How long does it take to receive the model?
    EZcohort® models program delivers a minimum of 4 mice that are at least heterozygous for the mutant alleles. They will be delivered to you in 14-16 weeks.

  • Can I breed these mice at my facility?
    Yes. Our conditions of use allow you to breed or crossbreed the mice for a perpetual term. This is included in the purchase price.

  • Can I get a genotyping protocol for my EZcohort® line?
    Yes. Genotyping protocols are provided as part of the project deliverable.

  • What if I want more than 4 mice?
    No problem. If you require more than 4 mice, we will put you in contact with one of our Scientific Program Managers. They will work with you to develop a breeding program that will meet the goals of your study. Learn more about Taconic's Scientific Services.

  • Can I request cryopreserved sperm or embryos?
    Unfortunately, we cannot provide cryopreserved materials.

  • What health standard are EZcohort® models delivered at?
    All mice are delivered at the Murine Pathogen Free™ health standard.

  • What if I want the models at a different health standard?
    We can deliver EZcohort® models at other health standards. We will have you engage with one of our Scientific Program Managers to discuss the specific needs of your project.

  • I searched all your models and can't find the one I require for my studies. Can you help?
    Yes. Taconic is a fully licensed provider of model generation services and Scientific Program Managers can help you. Please contact us with questions and for more information.

  • How are EZcohort® models different from the Knockout Repository, and GEM Collections?
    The GEM Collection and the Knockout Repository are collections of genetically engineered models with somewhat different licensing terms. Some GEM Collection models are restricted to non-profit customers.

  • Will I need to pay for shipping costs?
    Yes. Taconic Transit Cages and freight are charged separately.

  • What if the cryo-recovery fails?
    While we take every precaution to ensure a project is completed on time, in rare instances cryo-recoveries fail. If this should happen with your project, you will be contacted immediately. We will work with you to discuss the implications of the first attempt, and recommend the next steps. In many cases, we immediately schedule a second attempt to recover and provide a revision to the timeline.
