ABSTRACT:
Apparatus for measuring L-glutamine in a liquid sample includes a membrane on which are immobilized the enzymes glutaminase and glutamate oxidase, whereby any said L-glutamine in the sample is acted upon by the glutaminase to form glutamic acid, the glutamic acid being acted upon by the glutamate oxidase to form an enzymatic reaction product, the membrane being operatively associated with a sensor capable of sensing the enzymatic reaction product or a compound or element consumed or liberated in the formation or degradation thereof.
