Gibco™ Opti-MEM™ is a unique media that contains insulin, transferrin, hypoxanthine, thymidine, and trace elements. These additional components allow for a reduction in serum supplementation by at least 50%. Gibco™ Opti-MEM™ with GlutaMAX™ supplement minimizes toxic ammonia build-up and improves cell viability and growth in an easy-to-use format.

Gibco™ Opti-MEM™ uses a sodium bicarbonate buffer system (2.4 g/L) and therefore requires a 5-10% CO₂ environment to maintain physiological pH.
