BBI derives it’s purified Transferrin products from pooled normal human plasma from predominantly
US based paid blood donations.

The standard Transferrin products supplied by BBI are lyophilised products, material is available with different levels of iron saturation. Circulating Transferrin is partially Iron saturated however for cell culture use BBI adjusts the iron content to provide the following options:

Holo-transferrin (product code T101-5) is adjusted to give near 100% saturation (1200-1700 µg/gm).
Apo-transferrin (product code T100-5) is depleted to give near zero iron bound (<50µg/gm).
Customised Transferrin formulations are available on request.

Human plasma used for the manufacture of the BBI product human transferrin is collected at blood centers in the United States of America which are licensed by the United States Food and Drug Administration (FDA). The material is manufactured from a large pool of plasma donated by multiple donors, although the donor’s information is not made available, all donations are traceable back to the donor. All plasma donations are screened for infectious diseases by FDA approved methods at the donor level. Donations are ethically sourced and informed consent forms are signed by each donor prior to donation, the forms are kept on file by the approved collection facility. Further details on the collection process are available on specific information sheets or can be requested from technicalsupport@bbisolutions.com.

BBI prepares Transferrin under it’s ISO13485, 2016 quality system however the transferrin products are prepared in open laboratories and the material is not GMP/clinical grade. Transferrin is intended for research and cell culture use only and is not suitable for use in pharmaceuticals.

The specific methodologies are proprietary to BBI however a general purification methodology can be provided after execution of a Non-disclosure agreement.
