Important nutrients supports the embryo

G-1 is a medium for culture of human embryos from the pronucleate stage to day 2 or day 3. The medium contains amino acids to support embryo viability and hyaluronan to improve development and cryosurvivability and to facilitate implantation.

G-1 also contains lipoic acid as antioxidant to protect the embryo against reactive oxygen species during culture in vitro. 

Optimise all the way

Increase the chances of success at each stage of IVF. Ensure optimal conditions before, during and after culture by using the whole G-Series™. All G-Series media share the same basic composition to secure viability and implantation potential. Osmolality, pH and supporting compounds are all kept constant. This foundation prevents intracellular stresses as the embryos progress through the IVF process.
