ABSTRACT:
A reagent sheet for the measurement of GGT (.gamma.-glutamyl transferase) activity comprising a porous sheet containing a cationic surfactant and a self-developable substrate upon contact with .gamma.-glutamyl transferase. An integral multilayer analytical element for the measurement of GGT activity, comprising a porous spreading layer containing a cationic surfactant and a self-developable substrate in response to contact with .gamma.-glutamyl transferase, a water-absorbing layer and a support in a laminated form. The substrate can be either .gamma.-glutamyl-p-nitroamilide or .gamma.-glutamyl-3-carboxy-4-nitroamilide.
