EmbryoMax Advanced KSOM Medium is a new, uniquely buffered modified version of KSOM that can be used as a single medium to harvest and culture preimplantation mouse embryos. The medium will maintain pH out on the bench top and also grow embryos in vitro, replacing the normal 2-step system where one medium is used for embryo harvest and another is used for culture. The Advanced KSOM medium has been shown to produce a higher frequency of blastocyst formation in multiple mouse strains after 72 hours in culture when compared to standard KSOM medium.
Traditionally, retrieving and then growing mouse embryos in vitro is usually a 2-step system. Embryos are commonly removed from the oviducts in a HEPES buffered medium (e.g. M2, FHM), which maintain their pH in air. The embryos are then transferred into a second medium which is bicarbonate buffered (e.g. M16, CZB, KSOM) and placed in a CO2 incubator in order to maintain the pH of the medium. Furthermore, the bicarbonate buffered medium needs to be pre-equilibrated in the incubator for several hours prior to receiving embryos to achieve optimal growth. The EmbryoMax Advanced KSOM Medium enables both embryo handling in atmospheric conditions and culturing in a CO2 incubator with a single medium. No medium pre-equilibration step is necessary for embryo harvest, but pre-equilibration is recommended for culture.
