DNase & Methyl Green, 500g
Item #:
ABT/D04-102-500G
Supplier #: D04-102-500G
Supplier #: D04-102-500G
DNase Test Agar is used to detect deoxyribonuclease activity of bacteria and fungi, particularly for the identification of Staphylococci. Methyl Green combines with the polymerized DNA substrate to form a stable, green complex. The DNA is depolymerized by DNase-producing bacteria, which exhibit a clear zone against the green background around the colony. Tryptose is the nitrogenous source. Sodium Chloride maintains the osmotic balance and Agar is the gelifying agent.
DNase & Toluidine Blue, 500g
Item #:
ABT/D04-103-500G
Supplier #: D04-103-500G
Supplier #: D04-103-500G
DNase Test Agar is used to detect deoxyribonuclease activity of bacteria and fungi, particularly for the identification of Staphylococci. Tryptose provides nitrogenous sources, carbohydrates, minerals, and trace elements. Toluidine Blue allows for the detection of DNase activity on DNA, resulting in the production of a bright pink reaction due to the metachromatic property of this indicator. Some strains of Staphylococci may be inhibited on DNase Test Agar due to toluidine blueSodium Chloride maintains the osmotic balance and Agar is the gelifying agent.
