Recombinant Human Holo Transferrin Powder

CCM-RG-0082 is recombinant human holo transferrin, supplied as an animal origin-free powder for use as a defined iron-transport component in mammalian cell culture systems. Holo transferrin is the iron-loaded form of transferrin, enabling controlled delivery of ferric iron in media designs where serum, animal-derived extracts, or undefined additives are minimized. It is commonly evaluated in chemically defined, protein-containing, and serum-reduced formulations to support reproducible cell growth and productivity studies.

The product is categorized as a cell culture supplement and is suitable for procurement programs that require defined sourcing, powder format, and documented storage conditions. The stated shelf life is 48 months when stored as directed at -30 to -5 °C and protected from light. Shipping is performed on blue ice to support temperature control during transit. For related formulation components, see our cell culture reagents category.

• Supplementation of chemically defined and serum-reduced mammalian cell culture media where an animal origin-free iron carrier is required.
• Media optimization studies for CHO, HEK293, hybridoma, and other recombinant protein expression platforms using controlled iron availability.
• Replacement or reduction of serum-associated transferrin in R&D media development, clone screening, and scale-up comparability work.
• Use in custom feed or basal formulation studies where transferrin concentration is adjusted alongside insulin, trace elements, amino acids, and growth-supporting supplements.
• Process development experiments requiring lot-level documentation, consistent powder handling, and defined raw material selection for upstream workflows.

Store CCM-RG-0082 at -30 to -5 °C and protect the container from light. Keep sealed until use, and allow the container to equilibrate under controlled conditions before opening to reduce condensation exposure. Reconstitution concentration, diluent, filtration, and final working concentration should be selected according to the user’s validated medium formulation and cell line requirements. Use aseptic technique during weighing, reconstitution, and transfer. Avoid repeated temperature cycling and document opening date, operator, and remaining quantity for inventory control. The material is shipped on blue ice and should be moved to qualified frozen storage promptly on receipt.

CellCultureMedia supplies CCM-RG-0082 for research and bioprocessing use with procurement-ready documentation support.
