VANCOUVER, BRITISH COLUMBIA--(Marketwire - May 02, 2008) - Advanced Proteome Therapeutics Inc. - (APT), a subsidiary of Advanced Proteome Therapeutics Corporation (TSX VENTURE: APC) is pleased to announce the achievement of a significant milestone. Application of its kinetic labeling library technology has led to the development of chemical methods that enable the site-selective attachment of entities to human growth hormone, an established protein therapeutic. The methodology would thus far appear to be a general way of linking entities to proteins that can be used to modify their properties and lead to new, improved therapeutics.
