Latest Patents

Hiroshi Kisaki holds a patent for "Methods of producing proteins having triple-helix structure." The objective of this invention is to provide methods for producing human collagen molecules that are easy to isolate and purify. These collagen molecules have a structure that is substantially equivalent to that of natural collagen. The invention involves using host cells that are transduced with a collagen gene to synthesize large amounts of human collagen protein derived from a gene introduced into a high exogenous gene expression vector. The inventors discovered that a significant amount of human collagen, with minimal contamination from host cell-derived collagen, can be produced by selecting a host cell with low collagen expression and introducing a collagen gene construct into a suitable vector.
