Transferrin is the primary iron binding and cell delivery molecule present in serum. Serum-free cell culture systems require a delivery format for iron. Transferrin is the preferential delivery form of iron because cells process transferrin bound iron in a physiologically appropriate way through transferrin receptors on the cell surface. Human holo-transferrin is a high affinity transferrin that can be used with a wide range of cells types. Human holo-transferrin is loaded with iron prior to use and can be added directly to iron poor or iron-free cell culture media.
holo-Transferrin human has been supplemented in Roswell Park Memorial Institute (RPMI) for proerythroblasts proliferation assay and also in culture media for inductively coupled plasma emission spectroscopy.

  5. What is the carbohydrate content of human transferrin?

    We have found the information on transferrin in a reference book:The Plasma Proteins, F.W. Putnam, ed, volume 2, chapter 4, Table II.According to the table, Transferrin is 6 percent carbohydrate, citing G.A. Jamieson, J. Biol. Chem. 240(7), 2914-2920 (1965).The table also gives information on the percentage of each type of monosaccharide that is present.

Self-interacting chromatin domains encompass genes and their cis-regulatory elements; however, the three-dimensional form a domain takes, whether this relies on enhancer-promoter interactions, and the processes necessary to mediate the formation and maintenance of such domains, remain unclear. To examine these
