1x Park and Terasaki's Modification of McCoy 5A

1× Park and Terasaki's Modification Of McCoy 5A is used for the primary culture of cells from a wide range of tissues. Recommend for production of virus in primary cell cultures. It is excellent for the propagation of leukocytes, biopsy tissues, a broad range of human and rat normal and transformed cell types, and the most demanding primary and continuous cell lines.

McCoy’s media were originally formulated for the growth and support of human lymphocytes. The 5A modification originated as a reformulation of McCoy’s by Hsu and Kellogg. It was then further modified by Iwakata and Grace featuring increased levels of i-inositol and glucose. This final modification produced a media identical to RPMI 1629. McCoy’s 5A media support the indefinite proliferation of Walker 256 carcinoma cells. Park and Terasaki further added 25 mg/L of phenol red, to allow researchers to observe pH changes more readily. The Park and Terasaki Modification (PT) differs from the Iwakata and Grace Modication (IG) in that PT contains slightly modified levels of L-glutamic acid, glycine, L-hydroxyproline, L-proline, L-serine, L-threonine, L-tryptophan, and L-valine. The PT modification also contains the additions of penicillin, dihydrostreptomycin sulfate, gentamycin, fetal bovine serum and HEPES.

Originally developed to support liver tumor cells by modification of the amino acids found in BME. This formulation has also be used in the culture of bone marrow, skin, gingiva, kidney, omentum, adrenals, lung, spleen, rat embryos, and other cell types.
