Kyudo/Card Reagents for Mouse Sperm Cryoprotection,
Thawing and Mouse IVF

CARD FERTIUP® : CPA is a mouse sperm cryoprotectant.
CARD FERTIUP® : PM is a mouse sperm preincubation medium for use prior to IVF.
CARD MEDIUM® is a high-performance fertilization medium for the mouse in vitro fertilization procedure. Sperm cryopreservation carried out using CARD FERTIUP® reagents and CARD MEDIUM® allows for low cost and efficient preservation of mouse strains such as Tg or KO mice.

These reagents significantly improve in vitro fertilization rates of frozen and thawed sperm and fresh sperm with notoriously IVF-inefficient mouse strains such as C57BL/6 and 129. Use them to preserve, protect and defend the safety and reliability of your valuable mouse resources.

Benefits of using Card FERTIUP and CARD MEDIUM

• High fertilization rate (over 80%)
• Improvements in the management of genetically modified mice (Tg/KO)
• Reduction in labor, facilities, and breeding cost.
• Reduction in time required to expand a mouse colony
• Efficient production of strains which are notoriously difficult to breed

Fertilization rates using CARD FERTIUP® Preincubation Medium and CARD MEDIUM® for fresh and frozen sperm in various strains.

What They Do

CARD FERTIUP® Mouse Cryoprotectant guards against damage to spermatozoa during cryopreservation.

CARD FERTIUP® Mouse Preincubation Medium significantly increases the fertilizing ability of spermatozoa.

TCARD MEDIUM® works on the zona pellucida of oocytes to make them easier to fertilize.

Examples of Use

Even strains difficult to obtain via natural crossbreeding can be produced in a short period of time by treating fresh spermatozoa from a male mouse with CARD FERTIUP^® Mouse Preincubation Medium and CARD MEDIUM Medium^®, using the spermatozoa for in vitro fertilization, then transferring the embryos obtained into recipient parents.

You can also produce mouse pups without having a male mouse present by using cauda epididymis delivered safely and inexpensively to your lab using the CARD Cold Temperature Transport Kit. In this case cauda, it is recommended to incubate cauda epididymis spermatazoa in CARD FERTIUP® Preincubation Medium before in vitro fertilization with CARD Medium with CARD MEDIUM. Embryos so produced are then be transferred a female host. Obtained embryos can then be transferred into a recipient female.

High fertilization rates can be obtained even in strains known for their low in vitro fertilization rates such as 129 and BALB/c by preincubating spermatozoa in CARD FERTIUP® Mouse Preincubation Medium and CARD MEDIUM® prior to IVF in CARD MEDIUM®.

Sperm cryopreservation is a practical and cost-effective method of archiving mouse strains in the laboratory. CARD FERTIUP® and CARD MEDIUM® are high-performance media for mouse sperm cryopreservation, sperm preincubation and in vitro fertilization (IVF).

 

CARD FERTIUP® (mouse sperm cryoprotectant and mouse sperm preincubation medium) and CARD MEDIUM® (high-performance fertilization medium for in vitro fertilization) are high-performance reagents for mouse sperm cryopreservation, mouse sperm thawing (preincubation) and ithe n vitro fertilization (IVF) procedure .Sperm cryopreservation carried out using CARD FERTIUP® and CARD MEDIUM® allows for the low cost and efficient preservation of mouse strains (Tg or KO mice.).

They also significantly improve the in vitro fertilization rates of frozen-thawed sperm and fresh sperm taken from notoriously inefficient mouse strains such as C57BL/6 and 129. This reagent power trio will help you maintain the safety and reliable preservation of your valuable mouse resources.

When used in combination, CARD FERTIUP® and CARD MEDIUM® provide a high and stable fertilization rate using frozen-thawed mouse sperm with greatly improved fertilization rates for frozen-thawed sperm in C57BL/6 and 129 Mice strains, from less than 10% (using conventional methods) to more than 30%.

Using all three power trio reagents can enhance fertility rates to over 80%.

Ordering Information

CARD FERTIUP® Cryoprotectant : CPA

Fertiup® Cryoprotectant is a cryopreservation solution for mouse sperm that reduces sperm damage during freezing.
Improves sperm survival after thawing and subsequent in vitro fertilization. Sperm can be cryopreserved with high survival rate even with the C57BL / 6 and 129 lines, which were said to have low survival rates in conventional sperm freezing. Storage of genetic resources with frozen sperm is simpler than the method of storing fertilized eggs, and can be reduced to 1/30 or less compared to the cost of maintaining it in vivo. It is also used as a preparation for system disconnection and natural disasters due to unexpected accidents.

For Mouse Sperm Thawing and Pre-IVF Culture

CARD FERTIUP® Preincubation Media : PM

FFertiup® Cryoprotectant FERTIUP® Mouse Preincubation Medium : Mouse sperm preculture medium. This is a preculture medium that enhances the acquisition of fertility of mouse sperm. When used for in vitro fertilization with C57BL/6 mouse sperm prepared using CARD FERTIUP ® Mouse Sperm Cryopreservation Solution, an in vitro fertilization rate of 30% or more can be expected and efficient mouse fertilized eggs can be obtained. .. It is effective not only for freeze-thaw sperm but also for in vitro fertilization using fresh sperm significantly increases the fertilizing ability of spermatozoa.

For MOUSE In Vitro Fertilization Procedure

It is also used as a preparation for system disconnection and natural disasters due to unexpected accidents.

High performance in vitro fertilization medium This is an in vitro fertilization medium that acts on the zona pellucida of the egg during in vitro fertilization and improves the fertilization rate. Effective for various strains including C57/BL6 strain mouse. After fertilization, we have confirmed in vitro culture tests that normal development occurs from the pronuclear stage to the blastocyst. For in vitro fertilization between C57BL/6 mice , in vitro fertilization rate of 80% or more can be obtained by using CARD FERTIUP® mouse sperm preculture medium together.

The mouse sperm cryopreservation and in vitro fertilization system using CARD FERTIUP ® and CARD MEDIUM ® conserves the valuable genetic resources of mice.

CARD HyperOva® Ultra-Superovulation Reagent

CARD HyperOva® - a better superovulation reagent
CARD HyperOva® FD - a better superovulation reagent in a new, convenient freeze-dried format

CARD HyperOva® is an ultra-superovulation reagent that induces superovulation at higher efficiency than conventional methods with PMSG-hCG. Treatment with CARD HyperOva® yields 3-4 times more oocytes on average with C57BL/6J mice and is also effective with other strains. Moreover, further gains in efficiency can be realized by using CARD Medium during the IVF procedure.
