Glucosidase-transferase assay

The amount (unity) subtracted arises because the free n-glucose liberated by the debranching enzyme is also measured by the redudng-value assay for maltose. This procedure depends on the availability of purified glucosidase-transferase, and this is the main drawback to its application. However, the method has given values in good agreement with those afforded by other methods. ...
