TRANSFERRIN (HOLO) From: Human Serum Not less than 95% total protein. Each vial (lyophilized) contains 10 mg transferrin. The contents of each vial readily dissolve in 1 ml water. Transferrin is a transport factor used in cell culture work to convey essential metabolites to cells. Transferrin binds iron and makes this element available to cells in a recognizable form. Cellular iron is utilized as an enzymatic cofactor in key metabolic pathways such as the generation of ATP. The metabolic transport functions of transferrin make it a strong promoter of cell growth in cell culture (for example, high transferrin levels in MP CELLect™ Iron-Supplemented Calf Serum facilitate growth performance similar to FBS; data sheet available upon request). Transferrin is frequently used as a supplement when culturing cells in Serum-Free Media. 0 TO 5°C 160076 10 mg
