Glasgow's Minimum Essential Medium (GMEM) was originally developed by Ian McPherson and Michael Stoker as a modification of Eagle's medium. It was utilized to study the genetic factors which affected cell competence. Glasgow's MEM was developed for use with kidney cells lines, such as BHK-21.
The complete formulation is available.

Glasgow's MEM is unique from other media as it contains twice the concentration of amino acids and vitamins than the original Basal Medium Eagle, and is used without serum. Glasgow's MEM was originally formulated with 10% tryptose phosphate broth.

Product Intended Use
For in vitro diagnostic use. CAUTION: Not for human or animal therapeutic use. Uses other than the labeled intended use may be a violation of local law.

cGMP Manufacturing
Gibco® Glasgow's MEM 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.

Glasgow's MEM contains no proteins, lipids, or growth factors. Therefore, Glasgow's MEM requires supplementation, commonly with 10% tryptose phosphate broth. Glasgow's MEM uses a sodium bicarbonate buffer system (2.75 g /) and therefore requires a 5-10% CO₂ environment to maintain physiological pH.

Powder forms of Gibco® cell culture medium require sodium bicarbonate supplementation, pH adjustment, and filtration at the time of preparation (see protocol for details).
