What is the Principle involved in Keller-Kilianis Test?

The Keller-Kilianis test is based on the principle of iodine forming a blue color in the presence of starch. The test is used to detect the presence of reducing sugars in a solution, with the starch acting as an indicator to visually show the reaction.


What is the principle of heat coagulation test for proteins?

The principle of the heat coagulation test for proteins is based on the denaturation and coagulation of proteins when exposed to heat. By heating a solution containing proteins, the proteins unfold and aggregate, forming a visible clot or precipitate. This test is commonly used to assess the presence of specific proteins by noting the formation of a clot or precipitate upon heating.


What is principle of iodine test?

The principle of the iodine test is based on the ability of iodine to form a starch-iodine complex, which is a blue-black color. This test is commonly used to detect the presence of starch in a sample by observing a color change when iodine is added. If starch is present, the blue-black color will appear, indicating a positive result for the presence of starch.


What is the principle of agar diffusion method?

The principle of agar diffusion method is based on the diffusion of an antimicrobial agent from a sample into an agar medium containing a test organism. The size of the zone of inhibition that forms around the sample is used to determine the effectiveness of the antimicrobial agent against the test organism.


Principle involved in the test for phosphate of DNA?

The principle involved in the test for phosphate in DNA is based on the ability of phosphate ions to form a soluble complex with molybdate ions under acidic conditions. This forms a phosphomolybdate complex that can be detected using spectrophotometry, producing a blue color indicative of the presence of phosphate. This test is commonly known as the molybdenum blue assay.
