Abstract
This invention is about a novel Biomolecule Transduction Motif (BTM), Mph-1 peptide, which has a potential to transduce many biological response modifiers effectively into the cytoplasm, intracellular organelles or nucleus of prokaryotic or eukaryotic cells in vivo and in vitro, and the related technological methods using Mph-1 BTM. This Mph-1 BTM can be used for Durg Delivery System, development of new recombinant protein vaccines or DNA/RNA vaccines, gene and protein theraphy, production of pharmacologically or medicinally useful proteins or pharmacomedicinal drug therapy.
