Mca-RPPGFSAFK(Dnp)-OH Fluorogenic Peptide Substrate Summary

Purity
>95%, by HPLC.
Activity
The peptide substrate contains a highly fluorescent 7-methoxycoumarin group that is efficiently quenched by resonance energy transfer to the 2,4-dinitrophenyl group. It can be used to measure the activities of peptidases that are capable of cleaving an amide bond between the fluorescent group and the quencher group, causing an increase in fluorescence. It is an excellent substrate for endothelin-converting enzyme-1 (ECE-1) and neprilysin. The cleavage site by ECE-1 is the peptide bond between Ala and Phe (Johnson, G.D. and Ahn, K., 2000, Anal. Biochem. 286:112). The substrate is derived from bradykinin. It is also an excellent substrate for ACE and active Cathepsin A and X/Z/P.

Product Datasheets

Carrier Free

What does CF mean?

CF stands for Carrier Free (CF). We typically add Bovine Serum Albumin (BSA) as a carrier protein to our recombinant proteins. Adding a carrier protein enhances protein stability, increases shelf-life, and allows the recombinant protein to be stored at a more dilute concentration. The carrier free version does not contain BSA.

What formulation is right for me?

In general, we advise purchasing the recombinant protein with BSA for use in cell or tissue culture, or as an ELISA standard. In contrast, the carrier free protein is recommended for applications, in which the presence of BSA could interfere.

Mca-RPPGFSAFK(Dnp)-OH Fluorogenic Peptide Substrate
By Anonymous on 08/04/2016
Application:

ACE activity was determined following incubation with intramolecularly quenched synthetic ACE specific substrate Mca-RPGFSAFK (Dnp)-OH (R&D systems). In the case of cell lysates, 10 µg of total protein was assayed for activity in a buffer with the following composition: 50 mM MES (4-morpholineethanesulphonic acid), 300 mM NaCl, 10 µm ZnCl2 and 0.01% Triton X-100, pH 6.5. Reaction was initiated by the addition of 5×10−5 M substrate. Where applicable, recombinant enzymes were used at a concentration of 0.01 µg per reaction. The fluorescence measurements were performed in the black microtiter plates (Costar) in a total volume of 100 µl. The plates were read using a fluorescence plate reader SpectraMax M5 (Molecular Devices) at an excitation wavelength 320 nm and emission wavelength 405 nm Fluorescence resulting from the substrate hydrolysis increased with time, and achieved maximum by one h with recombinant enzyme however with cell/tissue lysates the maximum fluorescence was observed by four hours of incubation. Therefore fluorescence recorded at one and four hours of reaction time was taken for calculation of percent enzyme inhibition, when using recombinant enzymes and cell/tissue lysates, respectively. ACE activity was defined as the ACE inhibitor, captopril-sensitive fluorescence, and were expressed as percent inhibition.
