生物活性

N-Acetyl-DL-phenylalanine β-naphthyl ester is an aromatic amino acid ester, which functions as a chromogenic substrate for chymotrypsin and microbial serine proteases such as subtilisin[1].

体外研究
(In Vitro)

N-Acetyl-DL-phenylalanine β-naphthyl ester is hydrolyzed in the body by the esterase (APNEase) catalytic action at neutral pHs. APNEase level involves with many muscle wasting conditions suggest the possibility that it may be involved in the turnover and pathological breakdown of muscle proteins[1].
N-Acetyl-DL-phenylalanine β-naphthyl ester (0.75 mM, DMF; 3 min) as substrate and o-Dianisidine tetrazotized (oD) as the dye, allow the assessment of protease inhibitory activity directly from the yeast P. pastoris expression media[2].
N-Acetyl-DL-phenylalanine β-naphthyl ester (0.75 mM, DMF; 3 min) (2.4 g/L) provides a visualization result with stained agar gel via the diazo coupling of the β-naphtol produced by the enzymatic hydrolysis of N-Acetyl-DL-phenylalanine β-naphthyl ester (APNE). Circular zones containing inhibitor-proteinase complexes remain coloress while the region containing only proteinase shows a bright pink-purple color[3].
N-Acetyl-DL-phenylalanine β-naphthyl ester (5 mg/40 mL) has application: determine the class of peptidase in mouse plasma. The enzyme was displayed by immunoprecipitation with antiserum in radial immunodiffusion. After removal of non-precipitated serum and other constituents by washing in excess saline, individual rings of immunoprecipitate were incubated in a solution of a protease inhibitor, followed by washing and staining with the chromogenic substrate (NAPBNE and fast blue B), the picture can be photographed over direct lighting[4].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
