Gibco® MEM α is a modification of Minimum Essential Medium (MEM) that contains non-essential amino acids, sodium pyruvate, lipoic acid, vitamin B12, biotin, and ascorbic acid. MEM α is available without nucleosides for use as a selection medium for DG44 and other DHFR negative cells. This product is made with Earle’s salts.

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

cGMP Manufacturing and Quality System
Gibco® MEM α is manufactured at a cGMP compliant facility, located in Grand Island, New York. The facility is registered with the FDA as a medical device manufacturer and is certified to ISO 13485 standards. For supply chain continuity, we offer a comparable Gibco® MEM α product made in our Scotland facility (11900-016). This facility is registered with the FDA as a medical device manufacturer and is certified to the ISO 13485 standard.

MEM α contains no proteins, lipids, or growth factors. Therefore, MEM α requires supplementation, commonly with 10% Fetal Bovine Serum (FBS). MEM α uses a sodium bicarbonate buffer system (2.2 g/L) 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).

DMEM, no glucose (Gibco™)

DMEM (Dulbecco's Modified Eagle Medium) is a widely used basal medium for supporting the growth of many different mammalian cells. Cells successfully cultured in DMEM include primary fibroblasts, neurons, glial cells, HUVECs, and smooth muscle cells, as well as cell lines such as HeLa, 293, Cos-7, and PC-12. We offer a variety of DMEM modifications for a range of cell culture applications. Find the right formulation using the media selector tool.

This DMEM is modified as follows:
WithWithout
• L-glutamine• Glucose
• Phenol Red• Sodium Pyruvate
• HEPES

The complete formulation is available.

Using DMEM
DMEM is unique from other media as it contains 4 times the concentration of amino acids and vitamins than the original Eagle's Minimal Essential Medium. DMEM was originally formulated with low glucose (1 g/L) and sodium pyruvate, but is often used with higher glucose levels, with or without sodium pyruvate. DMEM contains no proteins, lipids, or growth factors. Therefore, DMEM requires supplementation, commonly with 10% Fetal Bovine Serum (FBS). DMEM uses a sodium bicarbonate buffer system (3.7 g/L), and therefore requires a 5–10% CO2 environment to maintain physiological pH.

cGMP manufacturing and quality system
For supply chain continuity, we manufacture DMEM at two separate facilities, located in Grand Island, NY and Scotland, UK. Both sites are compliant with cGMP-manufacturing requirements, are certified to ISO 13485, and are registered with the FDA as medical device manufacturers.

Advanced MEM (Gibco™)

Advanced MEM (Minimum Essential medium) is a widely used basal medium that allows the culture of mammalian cells with reduced Fetal Bovine Serum (FBS) supplementation. Compared to classic MEM, serum supplementation can be reduced by 50-90% with no change in growth rate or morphology.i Cells successfully cultured in Advanced DMEM / F-12, with no adaptation, include PK-15, MDCK, Vero, WI-38 and Hep-2.

This Advanced MEM is manufactured as follows:

WithWithout
• Glucose• L-glutamine
• Non Essential Amino Acids• HEPES
• Sodium pyruvate
• Phenol Red

The complete formulation is available.

Gibco® Advanced MEM is unique from other media due to addition of the following ingredients to allow for serum reduction: ethanolamine, glutathione, ascorbic acid, insulin, transferrin, AlbuMAX® I lipid-rich bovine serum albumin for cell culture, and the trace elements sodium selenite, ammonium metavanadate, cupric sulfate, and manganous chloride.

Product Use
For Research Use Only. Not intended for animal or human diagnostic or therapeutic use.

cGMP Manufacturing and Quality System
Gibco® Advanced MEM is manufactured at a cGMP compliant facility located in Grand Island, New York. The facility is registered with the FDA as a medical device manufacturer and is certified to the ISO 13485 standards.

Advanced MEM requires supplementation with 1-5% Fetal Bovine Serum and 4mM L-glutamine or GlutaMAX™ supplement. Many cell lines do not require adaptation to this media. The FBS concentration must be optimized for each cell line to obtain maximum serum reduction. Advanced DMEM uses a sodium bicarbonate buffer system (3.7 g/L) and therefore requires a 5-10% CO2 environment to maintain physiological pH.
