Biological activity of human plasma copper-binding growth factor glycyl-L-histidyl-L-lysine.

Plain Language Summary

The foundational discovery paper for GHK, characterizing glycyl-L-histidyl-L-lysine as a copper-binding growth factor isolated from human plasma. Establishes GHK's biological activities including stimulation of cell growth, copper transport, and tissue repair—the starting point for all subsequent GHK research. No abstract is indexed in PubMed for this early paper.
