These two solutions are mixed in equal amounts before the test and together are called Fehling’s reagents. Procedure of Fehling’s Test The Fehling’s test is done by first preparing the Fehling’s reagent which is a mixture of Fehling’s A and Fehling’s B and then adding the respective...
Tollen's Test: The test, also known as the silver mirror, is used to identify the presence of an aldehyde functional group in a compound. The test turns negative for ketone. However, an alpha hydroxy ketone gives a positive result.

The debranching activity of pullulanase was measured by the modified Tollens’ reaction and DNS method. For the DNS assay, 0.1 mL of serially diluted test samples were added into 0.3 mL of a reaction solution containing 0.8% (w/v) DNS, 0.2% (w/v) phenol, 2% (w/v) sodium potassium tar...
