Abstract
A rapid assay for serum amylase activity has been developed based on the use of a new chromogenic substrate—Cibachron Blue—amylose. The procedure requires 0.1 ml of serum and measures the production of soluble chromogen, the formation of which is linear with enzyme activity. Normal human serum has a mean amylase activity of 118 ± 37 (SD) mg dye/100 ml/15 min or, in international units, 78 ± 24 (SD) µg dye/min/ml. Excellent correlation was observed with a saccharometric amylase procedure.Keywords
