As a result of joint research carried out by ourselves and Kumamoto University, we have developed a number of reagents for use in rat reproductive engineering.
CARD FERTIUP® Rat Sperm Cryopreservation Agent
CARD FERTIUP® Rat Sperm Cryopreservation Agent is a newly-developed agent which enables researchers to efficiently carry out cryopreservation of rat sperm, which until now has been notoriously difficult to cryopreserve. Conventional rat sperm cryopreservation methods are unable to effectively maintain the motility of frozen-thawed sperm. On the other hand, rat sperm cryopreservation carried out using CARD FERTIUP® Rat Sperm Cryopreservation Agent yields superior motility even in frozen-thawed rat sperm, allowing for the production of many rat pups via IVF and embryo transfer.
CARD Rat IVF medium
CARD Rat IVF Medium is a new IVF medium developed specially for use in rat IVF.
ARD Rat Sperm Freezing kit
CARD Rat Sperm Freezing Kit is a kit that facilitates the effective production of high-quality frozen rat sperm during rat sperm cryopreservation using CARD FERTIUP® Rat Sperm Cryopreservation Agent. With this kit, researchers can appropriately carry out the rat sperm cooling process during rat sperm cryopreservation.
- Enables IVF to be carried out using frozen-thawed rat sperm.
- Contributes to a reduction in breeding costs through improvements in rat strain preservation efficiency.
- Facilitates the timely acquisition of live rats when they are required for experiments through application to genetically modified rats
