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

Product Specifications

>95%, by HPLC.
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 caspase-1/interleukin-converting enzyme (ICE) and angiotensin I-converting enzyme-2 (ACE-2) (Enari, M. et al., 1996, Nature 380:723; Vickers, C. et al., 2002, J. Biol. Chem. 277:14838). The cleavage sites by ICE and ACE-2 are the peptide bonds between Ala and Asp and between Pro and Lys, respectively.

Mca: (7-Methoxycoumarin-4-yl)acetyl, Dnp: 2, 4-Dinitrophenyl.

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.


Formulation Supplied as a stock solution in dimethyl sulfoxide (DMSO) at a concentration of 6.19 mg/mL or 4.0 mM.
Shipping The product is shipped with polar packs. Upon receipt, store it immediately at the temperature recommended below.
Stability & Storage: Samples are stable for up to twelve months from date of receipt at -20° C to -70° C. The substrate can be aliquoted and stored -20° C to -70° C in a manual defrost freezer for six months. Avoid repeated freeze-thaw cycles. Protect from exposure to direct light.

Mca-YVADAPK(Dnp)-OH Fluorogenic Peptide Substrate
By Shrinidh Joshi on 08/04/2016

ACE-2 activity was determined following incubation with intramolecularly quenched synthetic ACE-2 specific substrate 7-Mca-YVADAPK (Dnp) (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.
