L-glutamine is an essential amino acid required by virtually all mammalian and insect cells grown in culture. It is a crucial component of many cell culture media and serves as a major energy source for cells in culture. L-glutamine is very stable as a dry powder and as a frozen solution. However, in liquid media or stock solutions, L-glutamine can degrade relatively rapidly. L-glutamine is also more labile in cell culture solution than other amino acids.

Phenol red is used as a pH indicator in cell culture. Its colour exhibits a gradual transition from yellow to red over the pH range 6,8 to 8,2. Above pH 8,2, phenol red turns a bright pink (fuchsia) colour.

Egg yolk emulsion, sterile, VWR®

Supplier: BIOWEST

Concentrated solutions of amino acids, vitamins or non essential amino acids can be added to a basal medium to enrich it and the resulting medium used as a classical MEM or BME. The final concentration of the MEM or BME must be 1X.

Supplier: PanReac AppliChem

Water-soluble part of autolysed yeast. Rich of ammonia and vitamins, especially of water-soluble vitamin B-complexes; suitable for addition to media.

Accustase is a ready to use cell detachment solution of proteolytic and collagenolytic enzymes. Accutase is a direct gentle replacement for trypsin solution. It can also be used on suspension cells to reduce their agglutination in order to ease counting.

D-glucose monohydrate (Dextrose) is a common natural sugar involved in processes such as energy production, glycosylation, and formation of glycans that provide structure to cells. It is involved in a detrimental process in cells called glycation. It is used as a supplement for cell culture and in numerous cellular processes.

Trypsin is a porcine pancreas-derived enzyme that is commonly used for the dissociation and disaggregation of anchorage-dependent mammalian cells and tissues. The concentration of trypsin necessary to dislodge the cells from their substrate depends on the sensitivity of the cells.

Supplier: Corning

Corning® cellgro® COMPLETE formulation is based on a proprietary combination of 1:1 DMEM/F12, RPMI and McCoy's 5A medium. This medium contains a mixture of selected trace elements and high molecular weight carbohydrates, extra vitamins, animal origin-free protein, and a small amount of high quality bovine serum albumin (1,0 g/L). The Corning cellgro COMPLETE supports superior growth and viability over long-term passages in hybridomas, along with suspension and adherent cell cultures.
