DIAGNOSTIC DISCS 50 discs Code: DD 504
for detection of tributyrin hydrolysis
Purpose and usage:
TRIBUTYRIN diagnostic discs are used for the detection of the tributyrin hydrolysis. This test differentiates easily some bacterial species, e.g. branhamelae from neisseriae.
The hydrolysis of tributyrin is demonstrated by the change of the indicator color.
Prepare a dense suspension (degree No.3 of McFarland scale) of the tested strain in 1 ml of buffered saline and add 1 TRIBUTYRIN disc. Incubate at 37°C. The color reaction will develop after some hours. Final evaluation is to be made after 20 hours.
If the reaction is positive (Tributyrin+) the suspension turns yellow, if the reaction is negative (Tributyrin-) the color of the suspension remains red.
1. TRIBUTYRIN discs are designed for laboratory use only.
2. Discs should be stored in a dark place at +4°C and should not be used beyond the expiration date shown on the packing.
