Production of recombinant lactoferrin and lactoferrin polypeptides using cDNA sequences in various organisms

The verified cDNA sequences for human, bovine and porcine lactoferrin protein have been used to prepare recombinant lactoferrin for therapeutic and nutritional applications. Regions of the cDNA such as the Fe binding sites can be used to make an hLF polypeptide product. The present invention provides novel plasmids, transfected eucaryotic cells and methods of producing these plasmids and transfected eucaryotic cells. The novel plasmid contains the cDNA for lactoferrin protein. Methods for the production of lactoferrin protein in fungi and bacteria are also provided. Thus, the present invention provides an efficient and economical means for the production of recombinant lactoferrin protein and lactoferrin related polypeptides.

Production for recombinant lactoferrin and lactoferrin polypeptides

The subject invention provides for the production of lactoferrins and lactoferrin polypeptide fragments using the host cells Aspergillus in combination with novel plasmid constructs. More specifically, the subject invention provides novel vector constructs capable of producing lactoferrins and lactoferrin polypeptide fragments in Aspergillus host cells. More particularly, the subject invention provides for novel plasmid constructs suitable for use with Aspergillus and especially Aspergillus awamori, niger and oryzae host cells, which enables them to produce large amounts of recombinant lactoferrins and lactoferrin polypeptide fragments.
