FOA is a derivative of a pyrimidine precursor and is selectively toxic to yeast cells which synthesize orotidine-5’-phosphate decarboxylase. FOA has been used in a positive selection for uracil-requiring mutants(in the presence of large numbers of wild-type cells) lacking OMPdecase or OPRTase activities. This results in efficient strains for effective transformation systems.

High Growth Enhancement Medium is a modification of DMEM in which 3,6 g/L fructose is substituted for glucose, resulting in better pH control and higher cell yields. Fructose is metabolised slower than glucose, resulting in slower acid build up. This media is recommended for the growth and support of cells on microcarrier matrices.

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.

Ampicillin sodium salt is a semi-synthetic derivative of penicillin, active as a broad-spectrum antibiotic. It is inactivated by beta-lactamases and for this reason a beta-lactamase inhibitor should be considered when using ampicillin. Against gram-positive bacteria, ampicillin has a similar mode of action as benzylpenicillin; against gram-negative bacteria, it has a similar mode of action as chloramphenicol and tetracyclines. In E. coli it inhibits cell wall synthesis.
