01869 Hippurate Strips Kit for microbiology Hippurate Strips Test for identification of hippurate hydrolase activity of group B streptococci, Campylobacter jejuni, Gardnerella vaginalis and other microorganisms.
The test is based on hydrolysis of substrate (sodium hippurate) by the bacterial enzyme hippurate hydrolase and production of benzoic acid and glycine. Glycine produced by this enzymatic reaction is detected after 24 hours incubation in reaction with chromogen (ninhydrine) and the blue-purple substance is produced.
04739 Indoxyl Strips for microbiology Acetoxyindol Strips Diagnostic test for the rapid detection of the acetate esterase activity of microorganisms. The test is based on the reaction of free indoxyl groups with oxygen, which results in a colour change. Acetate esterase activity is present e.g. in Campylobacter spp., and in Moraxella (Branhamella) catarrhalis. The test is suitable for screening examinations and for the suspect microbial colonies identification. The result of the reaction is read after 3-5 min.
