PeproGrow-1 (Catalog # 700-C100) is designed to be used as a supplement to serum-free cell culture media formulations that can sustain the growth of adherent mammalian cell lines, and has been tested with HEK-293, HeLa, and A549 cells. This kit could potentially improve the culturing conditions of other adherent cells, but suitability for cells other than those pre-tested is not guaranteed. PeproGrow-1 is protein-free, has a chemically defined composition, and does not contain any animal-derived materials. It is intended specifically to be used with DMEM/F12 basal media (Invitrogen catalog # 10565*) and contains enough material to supplement 10L of media. *For customers outside the USA, use Invitrogen Catalog #31331
