Sodium dodecyl sulfate-polyacrylamide gel electrophoresis and ammonium sulfate fractionation were employed in series to purify and concentrate a 12.5-kDa protein fragment with a periodic (24-min period) proteinase K-resistant and drug-unresponsive NADH oxidase (CNOX) activity from pooled sera from healthy volunteers. The activity was unresponsive to capsaicin to distinguish it from the previously isolated cancer-associated NOX form (tNOX). Polyclonal antisera generated to the CNOX fragment cross-reacted with 20.5- to 24-kDa proteins of human sera, human lymphocytes, and plasma membranes from Escherichia coli with the molecular weight depending on source and conditions of treatment with proteinase K.
