An Improved Method for Preparation of Nitric Oxide Myoglobin

摘要

ABSTRACTWe developed an improved method for preparation of bovine nitric oxide myoglobin using the following starting materials: 0.1 mM purified metmyoglobin; 0.1 mM (7 ppm) sodium nitrite; and 1.76 mM (350 ppm) sodium ascorbate. The method requires complete deoxygenation of the reacting system. NOMb prepared in this manner is a source of cured meat pigment which contains a minimum of impurities, since the nitrite reacts quantitatively with the myoglobin in this method.
