The first culture medium specifically designed for time-lapse.
G-TL is a bicarbonate buffered medium containing hyaluronan and human serum albumin (5 mg/ml) for culture of embryos from fertilisation to the blastocyst stage and for transfer. Gx-TL has a unique combination of triple antioxidant protection for improved embryo viability.
Medium for culture of embryos from fertilisation to the blastocyst stage.
For use after pre-equilibration at +37°C and 6 % CO2.
Store dark at +2 to +8°C
Time-lapse culture removes time limits and stresses from embryos during assessment while adding power to classic morphology. G-TL is a medium in the G-Series™ designed to optimise the use of time-lapse technology, allowing truly undisturbed time-lapse culture.
Gx-TL has a unique triple antioxidant protection to improve embryo viablity. Acetyl-L-Carnitine, Alpha-Lipoic Acidand N-Acetyl-L-Cysteine are working together to protect the embryo from oxidative stress.
Reactive oxygen species are ubiquitous throughout any given IVF cycle. And they pose a significant threat to your embryo culture. To keep your embryos out of harm’s way, we have developed a unique triple antioxidant protection for improved embryo viability. The three antioxidants have been added to our culture media, Gx-TL, to form a protective barrier against oxidative stress.
G-TL provides uninterrupted culture conditions in an optimised culture environment to maximise embryo viability. The balanced mix of amino acids in G-TL is based on new knowledge about embryo metabolism and consumption of media constituents1. G-TL is designed to reduce ammonium load from breakdown products, while providing an optimised supply of amino acids for development.
G-TL has been shown to give high results when compared to sequential culture systems as well as monophasic culture systems.
Watch this movie where Dr. Silversand describes the development of G-TL as well as present clinical results from a multicentre prospective randomised trial.
The introduction of time-lapse technology has reduced the need of handling the embryo outside the incubator. Time-lapse technology has given a unique possibility to balance metabolic stress against less handling stress during embryo culture. Learn more in this blog post.
Watch Dr. Hardarson present results from an international, prospective, controlled and randomised multicentre study evaluating G-TL in a clinical environment using time-lapse technology.

Document and Ref: In a study presented at the ACE meeting in the UK, Shaw and co-workers compared single step time-lapse medium (Vitrolife, G-TL) with sequential series media (Sage, Quinn’s advantage) in large volume culture as well as micro drop culture. They found significantly higher day 5 blastocyst development rate in the G-TL group in both large and small volume culture.
