Background

CARD HyperOva® (Japanese Patent No. 5927588) is an ultra-superovulation reage nt that induces ovulation at higher efficiency when compared with the conventional superovulation induction me thod (PMSG-hCG method). following the conventional method, we were only able to obtain approximately 20 ova per mouse (C57BL/6J) on average; using CARD HyperOva®, however, we can obtain as many as 3-4 times more ova.

CARD HyperOva

Effects

  • Reduction in Experimental Animal Use (Contribution to 3Rs)
    Using CARD HyperOva® enables us to reduce the number of female mice used for ovum collection by 1/3-1/4.
  • Optimization of Genetically Modified mouse Creation and Preservation
    More ova can be obtained from less female mice using CARD HyperOva® than following the conventional method, which will facilitate in vitro fertilization and embryo transfer.
  • Application to Valuable Genetically modified Mice
    Using CARD HyperOva® on your valuable genetically modified mice enables you to obtain a lot of ova from small number of females, thus enabling the large-scale preparation of embryo
* 7.5 IU of CARD HyperOva® or PMSG was injected to four weeks old female mice, then 7.5 IU of hCG was administered 48 hours later. Thereafter all ova obtained 17 hours after the hCG injection were collected.
* The in vitro fertilization rate is defined as the number of 2-cell embryos divided by the total number of ova (mean±SD).
