P-dimethylaminobenzaldehyde, to test indole production in indole broth or for biochemical strip/cupule methods. Positive indole reactions with Kovac’s will turn pink to red. Does not require a xylene or chloroform extraction as with Ehrlich’s Reagent. Kovac’s Reagent is not for rapid spot indole on filter paper

Coagulase test is used to perform the coagulase test from isolated colonies. The coagulase test is
used for the identification of Staphylococcus aureus

Hydrogen peroxide 3%, (H2O2), catalase positive organisms (such as Staphylococcus) will evolve gas bubbles in the presence of H2O2.

Useful in the presumptive identification and differentiation of many bacteria. Beta-hemolytic organisms, such as Streptococcus species (catalase-negative), Staphylococcus species (catalase-positive), and Listeria species (catalase-positive) can be differentiated by their catalase reaction.

Oxidase Test is a liquid ready-to-use reagent that is used in procedures to detect
cytochrome oxidase activity in bacteria. Oxidase Powder can be used to prepare the oxidase reagent
