A technique for assessing the effects of pH and photodegradation on the stability of the iron chelate of ethyl N-methyl-4-hydroxy-5-oxo-3-pyrroline-3-carboxylate

A new chelation method for determining ATPase activity in skeletal muscle

Traditional methods for visualizing ATPase in sections use heavy metals that generate visible metal sulfide products. These methods use unpleasant and toxic reagents. We report a safer method using a novel ferric ion chelating agent to produce highly specific, low background, and permanent staining of muscle fiber enzymes.
