G-1™ PLUS provides the carbohydrates, amino acids and hyaluronan needed to support the embryo during the first critical stages of development.
G-1™ PLUS is a bicarbonate buffered media containing hyaluronan. It also contains human serum albumin (5 mg/ml).
Medium for culture of embryos from the pronucleate stage to day 2 or day 3
For use after equilibration at +37°C and 6 % CO2.
Store dark at +2 to +8°C
G-1 PLUS is a media for culture of human embryos from after fertilisation until the 8-cell stage. G-1 PLUS is supplemented with human serum albumin, HSA, and is ready to use. It contains amino acids to support embryo viability and hyaluronan to improve development and cryosurvivability and to facilitate implantation. It also contain lipoic acid as antioxidant to protect the embryo against reactive oxygen species during culture in vitro.
Each product in the G-Series™ is developed to resemble conditions in the female reproductive tract and fulfil embryo requirements.

Document and Ref: A study by Zhu et al demonstrate that extended culture before cryopreservation allows for selection of viable embryos with a high chance of implantation after warming. The high blastocyst formation rate (73.8%) using Vitrolife culture media, together with an efficient cryopreservation program resulting in survival rates of >96% should eliminate any earlier concerns about blastocyst culture and cryopreservation.
Document and Ref: A study by Kleijkers show that besides cell numbers and implantations rates, gene expression and certain pathways in preimplantation embryos are also affected by culture medium.
Document and Ref: Data from two studies presented at Annual Meeting of the Japanese Society of Clinical Embryologist show that good quality embryo rate and blastocyst development can be improved when using G-Series culture media (G-IVF, G-1 and G-2) from Vitrolife compared to a HTF-based non-hyaluronan containing media.
Document and Ref: In a study by Matsuoka et al, embryo culture was done either Vitrolife’s G-Series™ culture media or a mix of sequential culture media (control). The results show that good-quality blastocyst development was more frequent after culture in G-Series media containing hyaluronan.
