Cell culture media, Liebovitz L-15 medium
Supplier: Biowest
The Leibovitz L-15 media were formulated to promote the cell growth in medium not balanced in CO₂. The formulations were developed with the sodium bicarbonate buffer. The Leibovitz L-15 media are buffered by a complement of salts, free base amino acids and galactose so they can be used under conditions of free gaseous exchange with the atmosphere. When properly supplemented, L-15 Medium supports established cell lines, such as HEp-2 and LLC-MK2, as well as primary explants of embryonic and adult human tissue. Many viruses also have been successfully cultivated in this medium.

Cell culture salts, salt solutions and buffers
Supplier: Biowest
These irrigating buffers and salt solutions are sterile, physiological balanced solutions intended for use in the maintenance of mammalian cells, where a chemically defined, balanced salt solution provides an environment that will maintain the structural and physiological integrity of cells in vitro. Applications include the intermediate steps for cultivation of cells, like washing, centrifugation, suspending and counting, as well as for many analytical methods or biochemical treatments. Principally these solutions should be used to keep the cells in suspension only for minutes or a few hours maximum. These buffers and solutions are not cell culture media.

Versene
Supplier: Biowest
Versene can be used instead of trypsin. It is a chelating agent that disperses the cells by cutting the cytoplasmic bridges between them. Versene has the advantage of being able to withstand autoclave temperature, which is a guarantee of sterility. In addition, it is less aggressive cells than trypsin, which is useful for studies on cell growth.

Cell culture media, Iscove's Modified Dulbecco's Medium (IMDM)
Supplier: Biowest
In 1976, Guilbert and Iscove demonstrated that precursor cells of erythrocytes and macrophages could be cultured in a reduced-serum medium supplemented with albumin, transferrin, lecithin, and selenium. Iscove's medium is a modification of Dulbecco's Modified Eagle's Medium (DME) containing selenium, additional amino acids and vitamins, sodium pyruvate, HEPES buffer, and potassium nitrate instead of ferric nitrate. Further studies have demonstrated that Iscove's medium will support murine B lymphocytes, haemopoietic tissue from bone marrow, B-cells stimulated with lipopolysaccharide, T-lymphocytes, and a variety of hybrid cells.

Amphotericin B
Supplier: Biowest
Amphotericin B used in tissue culture to prevent growth of yeasts and fungi. It changes the function and integrity of eucaryotic cell membranes by forming complexes with sterols (cholesterol) hence having no effect on bacteria. Cause leakage of glucose.

Cell culture media, Schneider's Insect Medium
Supplier: Biowest
Schneider’s Insect Medium was developed to support the growth of excised imaginal discs from the fruit fly, Drosophila melanogaster. When supplemented with 5 to 20% heat-inactivated foetal bovine serum Schneider's mediuam has been found to support the rapid growth of both primary and established cultures of cells derived from Drosophila spp. and several other dipterans.

Cell culture media, DMEM-Ham's F12
Supplier: Biowest
Studies to determine the nutritional requirements of many cells have been in progress since Eagle's first reports. The major essential nutrients were identified, and work became focussed on the media requirements of individual cell types. Many media designed for these purposes are now available. Among the first of these media, developed initially to study hormonal requirements of cells in culture, was a mixture of DMEM and Ham's F12 medium, known as DMEM-Ham's F12.

Glutamine
Supplier: Biowest
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.
