Carrier Free

What does CF mean?

CF stands for Carrier Free (CF). We typically add Bovine Serum Albumin (BSA) as a carrier protein to our recombinant proteins. Adding a carrier protein enhances protein stability, increases shelf-life, and allows the recombinant protein to be stored at a more dilute concentration. The carrier free version does not contain BSA.

What formulation is right for me?

In general, we advise purchasing the recombinant protein with BSA for use in cell or tissue culture, or as an ELISA standard. In contrast, the carrier free protein is recommended for applications, in which the presence of BSA could interfere.

Background: Holo-Transferrin

Human Transferrin (Tf) is a single chain, 80 kDa member of the anion-binding superfamily of proteins (1 - 5). It is a bilobed molecule that is the product of an ancient gene duplication event (1, 6). Transferrin is synthesized as a 698 amino acid (aa) precursor that is divided into a 19 aa signal sequence plus a 679 aa mature segment that contains 19 intrachain disulfide bonds. The crystal structure of Tf reveals a protein with two flanking 340 aa globular domains. Each are composed of a beta -sheet surrounded by series of alpha -helices (1, 7). The N- and C-terminal flanking regions (or domains) will bind ferric iron through the interaction of an obligate anion (usually bicarbonate) and four amino acids (His, Asp, and two Tyr) (7, 8). Apotransferrin (or iron‑free) will initially bind one atom of iron at the C-terminus, and this is followed by subsequent iron binding by the N‑terminus to form holotransferrin (diferric Tf) (8, 9). Through its C-terminal iron‑binding domain, holotransferrin will interact with the type I Tf receptor (TfR) on the surface of cells where it is internalized into acidified endosomes. Iron dissociates from the Tf molecule within these endosomes, and is transported into the cytosol as ferrous iron. At physiological pH, iron‑free apotransferrin is not bound by TfR. But at acidic pH, such as exists in the endosome, apotransferrin has considerable affinity for TfR. Thus, it remains bound to TfR and is recycled back to the cell surface where a neutral pH environment dissociates ligand from receptor. Each Tf molecule recycles 100 - 150 times during its lifetime (8 - 11). In addition to TfR, transferrin is reported to bind to cubulin, IGFBP3, microbial iron‑binding proteins and liver-specific TfR2 (7, 12, 13, 14). Transferrin is variably glycosylated and the degree of sialylation is suggestive of certain clinical conditions (15). Finally, Tf is highly allelic and the gene codominant, with many single aa changes noted. Three general forms are known, based on standard electrophoretic mobility. Fast Tf is known as transferrin B, slow transferrin is transferrin D, and the middle migrating transferrin is type/variant C, thre most common (16, 17). Mature human TF is 73% aa identical to both mouse and rat Tf, and 68% and 71% aa identical to bovine and equine Tf, respectively.

FAQs

  1. What are the differences between Human Holo-Transferrin Protein, CF (Catalog # 2914-HT) and Human Apo-Transferrin Protein, CF (Catalog # 3188-AT)?

    • Human Transferrin has two different iron binding domains, one at the N-terminus and one at the C-terminus. Apo-transferrin (3188-AT) is not bound to any iron atoms and Holo-Transferrin (2914-HT) has an iron atom bound at both the N- and C-terminal domains.

  2. When I opened the vial of Human Holo-Transferrin Protein, CF (catalog # 2914-HT), the white powder turned red in color - is that normal?

    • The holo-transferrin proteinis saturated with iron and the appearance of pink to dark orange/red color is consistent with our manufacturing observations.
