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.

Ham's F12 was originally developed for the serum-free clonal growth of Chinese Hamster Ovary (CHO) cells, lung cells and mouse L-cells. It is frequently used with dialysed serum, hormones, selenium and other supplements for serum-free cultures. It is the medium of choice for supporting the growth of cells of rodent origin, particularly rabbit and rat and has proved to be an excellent cloning medium for the culture of myeloma and hybrid cells.

McCoy’s media were originally formulated for growth and support of lymphocytes. This final modification produced a medium identical to RPMI 1629. McCoy's 5A media supports the indefinite proliferation of Walker 256 carcinoma cells. In addition, it is excellent for the propagation of leukocytes, biopsy tissues, a broad range of human and rat normal or transformed cell types, the most current primary and continuous cell lines.

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.

Colcemid arrests the division of cells in mitosis. It prevents the formation of the spindle apparatus responsible for cell division, thereby permitting an accumulation of metaphases.

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.

RPMI are general purpose enriched media with extensive applications for a broad spectrum of mammalian and hybridoma cells, including human myeloma, mouse hybridoma, human leukocytes, and B and T lymphocytes. It was originally formulated for suspension cultures and monolayer culture of human leukaemia cells.

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.

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.

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.

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.

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.

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.
