Description

Perform motility testing in microorganisms using Motility Test Medium w/TTC Indicator.

Demonstrate motility in microorganisms with Thermo Scientific™ Remel™ Motility Test Medium w/TTC Indicator.

Motility Test Medium w/TTC Indicator is a modification of the formulation of Tittsler and Sandholzer for detection of motility in enteric gram-negative bacilli1. When results of motility determinations in hanging-drop preparations and semi-solid agar were compared, they observed perfect correlation2. Kelly and Fulton recommended the addition of a tetrazolium salt to enhance the macroscopic appearance of motile organisms in motility media3.

Motility Test Medium w/TTC Indicator is a semisolid media that is used to demonstrate motility in microorganisms. Agar provides a semisolid medium which allows macroscopic motility interpretations. TTC (2,3,5-triphenyltetrazolium chloride) allows visual enhancement of bacterial growth. Tetrazolium salt is colorless, but as the organism grows the dye is incorporated into bacterial cells and is reduced to an insoluble red pigment, formazan. This red color forms only in the area where bacteria is growing.

  • Ready-to-use: Convenience of prepared media
  • Easy to interpret: Observable color change

When TTC is added to the medium, red color develops in the area of bacterial growth.

Motility Test Medium w/TTC Indicator contains gelatin peptone and beef extract that supply vitamins and nitrogenous compounds essential for bacterial growth. Sodium chloride provide essential electrolytes and maintains osmotic equilibrium. TTC Indicator aids visual enhancement of bacterial growth.
