Thermo Scientific™ LAP Disk w/Reagent

Description

• Rapidly detect leucine aminopeptidase activity in streptococci and related genera using Thermo Scientific™ Remel™ LAP Disk with Reagent
• In 1984, Colman and Ball reported that, unlike streptococci, Aerococcus species do not produce leucine aminopeptidase (LAP) 1
• Aerococcus strains were found to be consistently negative for leucine aminopeptidase, while strains of Enterococcus and Streptococcus gave positive reactions
• LAP, in conjunction with PYR and other conventional tests, is an important parameter in the identification of Aerococcus, Leuconostoc, Pediococcus , and related genera 2-4
• Leucine aminopeptidases (LAPs) are a diverse set of exopeptidases that catalyze the hydrolysis of leucine residues from the amino termini of proteins or peptides
• LAPs are ubiquitous enzymes present among animals, plants, prokaryotes and microbes
• The LAP test should be performed on pure or isolated cultures of catalase-negative, Gram-positive cocci which are 18-72 hours old
• Ready to use: Reagent-impregnated disc
• Rapid test: Results are obtained within 5 to 6 minutes
• Easy to identify: A color change from pink to red indicates a positive test whereas no color change or a slightly yellow color indicates a negative test.
