What Our Customers Say

“Among several commercial services who have claimed to be specialized to generate mouse models with genetic modifications, I recognize that Cyagen is one of the best. We are looking forward to having more cooperation with them.”

embryo and sperm cryopreservation
Cryoperservation of embryos and/or sperm is an ideal solution to maintain a live animal colony for strains that are rarely used. This backup can save significant space and prevent loss due to disease or in case an issue arises within your animal facility, providing an alternative to manage the colonies that will be used for research. Cyagen can back up your live animal colony by our embryo and sperm cryopreservation services, which can not only protect your valuable strains but also reduce your cost in the long run. We also can produce live animals for you in eight to twelve weeks once your cryopreserved stock is preserved at Cyagen.

◆ Cryopreservation Service

1. Embryo Cryoperservation

Embryo cryopreservation allows you to safeguard valuable research strains against loss caused by disease, breeding cessation or problems within your facility. With Cyagen's embryo cryopreservation service, you can protect your valuable strains with reduced cost in the long term. Procedures for embryo cryopreservation include superovulation of embryo donors (generally, female mice aged 3-4 weeks of the same background as the embryo donors.), mating of superovulated females to male mice, collection of two-cell embryos, cryopreservation of two-cell embryos, quality control throughout cryopreservation process and storage in liquid nitrogen.

 

2. Sperm Cryoperservation

Sperm cryopreservation creates a cost-effective and safety way to protect live animal colonies. Cyagen offers sperm cryopreservation service to back up your live animal colonies. Procedures for sperm cryopreservation include euthanizing 2 male mice from each line to be cryopreserved, collection and cryopreservation of sperm, quality control throughout cryopreservation process and storage in liquid nitrogen in liquid nitrogen.
