B7260 Nα-Benzoyl-L-arginine-7-amido-4-methylcoumarin hydrochloride protease substrate  
B4500 Nα-Benzoyl-L-arginine ethyl ester hydrochloride trypsin substrate  
B4750 Nα-Benzoyl-DL-arginine β-naphthylamide hydrochloride trypsin substrate Nα-Benzoyl-DL-arginine β-naphthylamide hydrochloride (BANA) helps to determine the activities of cathepsin B and papain. BANA test is also useful in identifying the number of periodontal sites with periodontal pathogens. Presence of volatile sulfur compounds (VSCs), synthesized by oral bacteria in dental plaque or tongue coating can be colorimetrically confirmed by their ability to hydrolyze N-benzoyl-DL-arginine-2-naphthylamide.
