Mouse Embryo Media
Mouse whole embryo culture is an important method employed in mammalian developmental biology and birth defects research. This technique enables longitudinal studies of explanted rodent embryos at the organogenesis stage. An essential technique for creating transgenic mice uses the transformation and injection of stably transfected mouse embryonic stem cells (ES) into mouse blastocysts. To optimize embryo collection, manipulation, and transfer techniques, we offer a complete selection of mouse embryo media and reagents.

PluriSTEM® Human ES/iPS Cell Medium
Defined small molecule based serum-free medium that enables feeder-free culture of human ES/iPS cells and allows for media exchanges every other day without compromising the morphology or long term functionality of human pluripotent stem cells.

D-(+)-Glucose
suitable for mouse embryo cell culture, ≥99.5% (GC)
Hepes-based media for embryo handling and manipulation
- M2 media is often used for embryo collection, and for extended handling outside the culture incubator
- FHM is a modification of the KSOM formulation, also used for manipulating embryos outside CO2 incubation environments
Bicarbonate-based media for the culture and development of embryos
- Modified M16 media: traditional embryo culture media based on Krebs-Ringer bicarbonate buffer
- KSOM media allows embryos to overcome the two-cell block and supports enhanced cell division. Our proprietary formulation provides higher yields of blastocyst development
All media are tested in mouse embryo culture and manufactured using premium quality raw materials.
EmbryoMax® Advanced KSOM Medium
EmbryoMax® Advanced KSOM Medium is an all-in-one medium for the harvest and culture of mouse embryos, replacing the traditional two-step system where unique, separate formulations are required for embryo harvest and culture. Our advanced KSOM formulation enables both handling of embryos in atmospheric conditions and culturing in a CO2-controlled incubator - with a single medium.
