HYDROTROPE-INDUCED MICELLAR PHASE OF SODIUM DODECYL SULFATE AS NEW DETERGENT FOR EXTRACTION AND STABILIZATION OF PROTEINS

X-ray phase analysis and IR spectroscopy data have confirmed a gel-like nature of sodium dodecyl sulfate micellar phase induced by sodium chloride and salicylic acid additives. This phase essentially consists of water (omega(H2O) > 50 %), which is connected with main components of the micellar-extraction system through intermolecular hydrogen bonds. Capacity of such micellar phase to quantitatively extract of proteins (R > 94 %) with saving of their catalytic activities and dispersity was found.
