Application
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.
Biochem/physiol Actions
Provides iron to cells in a physiologically stable and safe form.

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
