Dec 01, 2009· In evaluations of new susceptibility testing methods it is important to examine a representative number of strains that are resistant to various drugs to verify the ability of the new test to detect resistance and to test a number of susceptible strains to determine the rate of major errors that might be expected in a typical clinical laboratory setting [16, 21].
In western blot, primary antibody should be validated before use. The choice of a primary antibody depends on the antigen to be detected. Both polyclonal and monoclonal antibodies work well for western blot. Monoclonal antibodies recognize single specific antigenic epitope. Thus, they have higher specificity resulting in lower background.
Aug 20, 2019· PRINCIPLE: Ninhydrin is the powerful oxidising agent. It causes oxidative decarboxylation of amino acids,, Amino acids, on heating with ninhydrin, are oxidatively decarboxylated, producing carbon dioxide (CO2), ammonia (NH3), and an aldehyde. Reduced ninhydrin then reacts with the liberated ammonia and a blue or purple coloured complex is produced.
