Description

Application

Recommended for the detection of urease activity.

Biochem/physiol Actions

Urea solution is primarily used for protein denaturation. It also increases solubility of hydrocarbons and reduce micelle formation. Urea solution at high concentration leads to the destabilization of amyloid β16−22 oligomers.

Preparation Note

Warm the refrigerated 40% urea solution to room temperature. Aseptically add 5 mL to 95 mL of sterile molten Urea Agar Base (Christensen). Mix well and dispense in sterile tubes.
