Gibco™ William's E Medium is a modification of earlier media that has been enriched in amino acids and double the glucose. William's E Medium contains unique ingredients, including zinc, iron, manganese, non-essential amino acids, the reducing agent glutathione and the lipid methyl linoleate.

Dual-Site cGMP Manufacturing

Gibco™ William's E Medium is manufactured at a cGMP compliant facility, located in Paisley, Scotland, UK. The facility is registered with the FDA as a medical device manufacturer and is certified to the ISO 13485 standard. For supply chain continuity, we offer a comparable Gibco™ William's E Medium product made in our Grand Island facility (12551-032). This facility is registered with the FDA as a medical device manufacturer and is certified to the ISO 13485 standards.

William's E Medium contains no proteins or growth factors. Therefore, William's E Medium requires supplementation, commonly with 5-10% Fetal Bovine Serum (FBS). William's E Medium uses a sodium bicarbonate buffer system (2.2 g/L) and therefore requires a 5-10% CO₂ environment to maintain physiological pH.
