LAP Test- Principle, Procedure, Results, Uses


The LAP test is a biochemical test that is used to assess the ability of bacteria to synthesize leucine aminopeptidases enzymes. These enzymes are involved in the hydrolysis of amino acids from the N-terminal end of peptides and proteins. The LAP test can also be used to differentiate and presumptively identify catalase-negative Gram-positive cocci bacteria, such as Streptococcus spp., Enterococcus spp., Lactococcus spp., and Pediococcus spp.
