Blood Substitutes

Study results from University of Stirling broaden understanding of blood substitutes

Published in Blood Weekly, April 3rd, 2008

According to recent research from Scotland, "The enzymatic activity of phenoloxidase is assayed routinely in the presence of SDS. Similar assay conditions elicit phenoloxidase activity in another type 3 copper protein, namely hemocyanin, which normally functions as an oxygen carrier."

"The nature of the conformational changes induced in type 3 copper proteins by the denaturant SDS is unknown. This comparative study demonstrates that arthropod hemocyanins can be converted from being an oxygen carrier to a form which exhibits phenoloxidase activity by incubation with SDS, with accompanying changes in secondary and tertiary structure," wrote S. Baird and colleagues,...
