It is a kind of iron-binding blood plasmaglycoproteins that is capable of regulating the level of free iron (Fe) in biological fluids. It is responsible for iron transportation in vertebrate serum and donating irons to cells through interaction with the CD71 membrane receptor. Transferrin is crucial for proliferating cells as a growth factor to initiate and maintain the DNA synthesis. It can also act as a cytokine. It is mainly synthesized in liver inside the human body. It is responsible to deliver iron from duodenum and white blood cells macrophages to all the other tissues, and is a key protein to maintain in vivo iron homeostasis. Increased plasma transferrin level is related to diseases such as iron deficiency anemia while decrease plasma transferrin is related to iron overload diseases and protein malnutrition. Uses Transferrin (Holo) is the primary iron binding and cell delivery molecule present in serum. Serum-free cell culture systems require a delivery format for iron. It 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. It can be used with a wide range of cells types. It is loaded with iron prior to use and can be added directly to iron poor or iron-free cell culture media. It has been used for study in treatment of breast cancer cells with holo-transferrin in combination with dihydroartemisinin results in increased tumor cell death due to elevated levels of intracellular ferrous iron. Uses 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. Uses All cells require iron for the proper uptake of oxygen from their environment. Transferrin, a protein isolated from serum, causes the uptake and transport of iron from culture medium to the cells. This allows proper oxygen uptake and also stimulates growth-related enzyme activity. Iron-saturated transferrin (holo transferrin) is continually recycled after releasing iron and becomes iron-deficient transferrin (apo-transferrin). Choosing which form to use depends upon the culture conditions. In media such as Dulbecco′s Modified Eagle′s Medium/Ham′s Nutrient Mixture F12 (DMEM/F12) that contain high levels of iron salt, using apo-transferrin is preferred. General Description Transferrin is an 80 kDa serum glycoprotein, which has an half-life of 8 to 10 days. The gene is located on human chromosome 3q22.1. Transferrin is expressed in hepatocytes. Pharmaceutical Applications Transferrins are a group of proteins that are abundant in blood and their primary role is to transport Fe3+, as free Fe3+ would be toxic to most organisms. Transferrin consists of a single polypeptide chain independently binding a maximum of two Fe3+ ions. Fe3+ is bound in a hexa-coordinated high-spin complex within the protein. The metal is coordinated by the N atom from the imidazole residue, two deprotonated phenol groups, a carboxylate and a carbonato ligand. Biochem/physiol Actions Studies have shown that co-treatment of breast cancer cells with holo-transferrin, which increases iron levels within cells and derivatives of artemisinin results in increased cell death. Purification Methods This transferrin is purified by affinity chromatography on phenyl-boronate agarose followed by DEAE-Sephacel chromatography. The product is free from haemopexin. [Cook et al.

Especially in the field of vitamins, amino acids, pharmaceutical raw materials and cosmetic raw materials, we have more than 20 years of production and sales experience. All products meet the requirements of high international export standards and have been recognized by customers all over the world. Our manufacture basement & R&D center located in National Aerospace Economic & Technical Development Zone Xi`an Shaanxi China. Now not only relying on self-cultivation and development as well as maintains good cooperative relations with many famous research institutes and universities in China. Now, we have closely cooperation with Shanghai Institute of Organic Chemistry of Chinese Academy of Science, Beijing Institute of Material Medical of Chinese Academy of Medical Science, China Pharmaceutical University, Zhejiang University. Closely cooperation with them not only integrating Science and technology resources, but also increasing the R&D speed and improving our R&D power. Offering Powerful Tech supporting Platform for group development. Keep serve the manufacture and the market as the R&D central task, focus on the technical research.  Now there are 3 technology R & D platforms including biological extract, microorganism fermentation and chemical synthesis, and can independently research and develop kinds of difficult APIs and pharmaceutical intermediates. With the strong support of China State Institute of Pharmaceutical Industry (hereinafter short for CSIPI), earlier known as Shanghai Institute of Pharmaceutical Industry (SIPI), we have unique advantages in the R & D and industrialization of high-grade, precision and advanced products.  Now our Group technical force is abundant, existing staff more that 1000 people, senior professional and technical staff accounted for more than 50% of the total number of employees, including 15 PhD research and development personnel, 5 master′ S degree in technical and management personnel 9 people. We have advanced equipment like fermentation equipment and technology also extraction, isolation, purification, synthesis with rich production experience and strict quality control system, According to the GMP required, quickly transforming the R&D results to industrial production in time, it is our advantages and our products are exported to North and South America, Europe, Middle East, Africa, and other five continents and scale the forefront in the nation, won good international reputation.  We believe only good quality can bring good cooperation, quality is our key spirit during our production, we are warmly welcome clients and partner from all over the world contact us for everlasting cooperation, Leader will be your strong, sincere and reliable partner in China.
