Abstract
Studies of enzyme kinetics by histochemical methods has been seriously impaired by available methods. This study combines two newer methods, i.e., sectioning undecalcified bone from glycol methacrylate and the use of atomic absorpton spectrophotometry for photographic densitometry. The results indicate that the substrate concentration for zero order kinetics of the alkaline phosphatase reaction in bone is 0.5 mg/ml of substrate; and the Km of the same reaction is estimated to be 0.25 mg/ml or 0.56 mM of substrate.
