LanaGram™, rapid color test for bacterial gram reaction

For organisms that are difficult to gram stain. Uses the aminopeptidase reaction. LanaGram™ confirms the gram stain reaction of gram-negative and gram-positive aerobic or facultatively anaerobic rods or coccobacilli. This test is not recommended for use with gram-positive cocci, microaerophilic or obligate anaerobic organisms.

LanaGram™ produces a rapid color change in a tube, gram negatives turn yellow, gram positives remain clear. Ideal for Bacillus, Listeria, Lactobacillus, and non-fermentors, all of which can be difficult to gram stain.
