Description

Description générale

BACTIDENT^™ Aminopeptidase test strips are diagnostic test strips used in microbiology to detect the activity of aminopeptidase enzymes in bacterial strains. Aminopeptidases are a group of enzymes that cleave amino acids from the amino terminus of polypeptides and proteins. The test strips contain L-alanine-4-nitroanilide as a substrate, which is split into 4-nitroaniline and the amino acid L-alanine in the presence of the enzyme alanine aminotransferase. The L-alanine aminopeptidase enzyme is localized in the cell envelope of bacteria, and the development of clear yellow coloration of 4-nitroaniline indicates the presence of the enzyme.

Application

BACTIDENT^™ Aminopeptidase test strips are useful for bioburden testing in the industry. The aminopeptidase test is a reliable method for determining the Gram behavior and differentiating Gram-positive from Gram-negative bacteria. These test strips are used for the detection of L-alanine aminopeptidase-producing microorganisms. The test is particularly useful in identifying Enterobacteriaceae and in differentiating between species of clinically important bacteria such as Streptococcus and Enterococcus.
