Gram Negative Strips
Gram Negative Strips
Rapid diagnostic test for aminopeptidase enzyme present in the cell membrane of Gram negative bacteria.
Gram Negative Strips provide rapid differentiation of Gram–positive and Gram-negative aerobes and facultative anaerobes. The test detects cell wall aminopeptidase present in Gram-negative organisms by using the chromogenic substrate L-aniline-4-nitroanilide (LANA). Each strip is impregnated with LANA (colourless), and the aminopeptidase hydrolyses LANA yielding bright yellow nitroaniline. Gram-positive organisms do not produce any colour change. The technique is convenient, reliable and clean! It has been shown to work in the presence of non-cultivable organisms, allowing their Gram classification to be assigned.
Description: Paper strip impregnated with L-alanine-4-nitroanilide.
Method of use: First moisten printed zones on strip with activating agent from dropper bottle. Using wire or plastic loop (such as Microloop), touch 2 or 3 colonies of test organism on agar medium. Smear organism onto test zone on the strip. Positive result is indicated within a one minute by smeared area turning bright yellow.
