CAUTIOUS
This test is worded and codified by unit to make the order easier, but it is always packaged in kit of 30 sticks.
Definition
Test for distinguishing Gram-negative bacteria from Gram-positive
Specifications
- The reagent l-alanine-4-nitroanilide is hydrolysed by the enzyme amino-peptidase contained in the cell of Gram-negative bacterial micro-organisms
- The sticks are impregnated with the reagent L-alanine-4-nitroanilide which, on contact with colonies of Gram-negative bacterial colonies, reacts by changing colour to blue-violet following addition of the detector reagent (Gram Test Reagent).
Components
- 30 impregnated sticks contained in a heat-sealed container
- 1 Gram Test Reagent (detector agent)
- 1 instruction sheet
