Mca-(ala7,lys(dnp)9)-bradykinin is a sensitive fluorogenic substrate for ECE-1 (endothelin-converting enzyme-1). The incorporation of a (7-methoxycoumarin-4-yl)acetyl (Mca) fluorescent group and a 2,4-dinitrophenyl (Dnp) quenching group has resulted in a large fluorescence increase upon substrate cleavage .

Dabcyl-QALPETGEE-Edans is a synthetic peptide substrate for fluorescence resonance energy transfer (FRET) detection of Sortase A (SrtA) enzymatic activity. Dabcyl-QALPETGEE-Edans is labeled at both ends with the fluorescent group Edans (donor) and the quencher Dabcyl (acceptor), respectively. Dabcyl-QALPETGEE-Edans's central sequence contains a conserved motif specifically recognized by SrtA. Dabcyl-QALPETGEE-Edans demonstrates high sensitivity in vitro assays, enabling precise determination of the half-maximal inhibitory concentration of SrtA .

Dnp-RPLALWRS TFA is a fluorescent peptide substrate designed for human matrilysin (MMP-7). After enzymatic cleavage of Dnp-RPLALWRS TFA at the alanine-leucine bond, the release of the Dnp group alleviates fluorescence quenching, thereby enabling real-time quantitative analysis of MMP-7 activity by increasing tryptophan emission. Dnp-RPLALWRS TFA provides a sensitive and efficient detection method for kinetic studies and inhibitor screenin .

CHIKV Virus Protease

Research Areas:  

Infection

DABCYL-RAGGYIFS-(E-EDANS)-NH2, an octapeptide, is a FRET-based substrate peptide of CHIKV nsP2protease with highly sensitivity. DABCYL-RAGGYIFS-(E-EDANS)-NH2 can be cleaved by the active CHIKV nsP2protease, separating fluorophore and quencher and resulting in an increase of fluorescence signal. DABCYL-RAGGYIFS-(E-EDANS)-NH2 can used for the determination of CHIKV nsP2protease activity .

Cathepsin

Others

Cathepsin E substrate e is a substrate of Cathepsin E. Cathepsin E substrate e was designed in such a way that due to the close proximity of a Mca-donor and a Dnp-acceptor, a near complete intramolecular quenching effect was achieved in its intact state. After the proteolytic cleavage of the hydrophobic motif of the peptide substrate, both Mca and Dnp would be further apart, resulting in bright fluorescence .

Mca-SEVNLDAEFK(Dnp) is a Beta-secretase 1 (BACE-1) peptide FRET substrate, containing the 'Swedish' Lys-Met/Asn-Leu mutation of the amyloid precursor protein (APP) β-secretase cleavage site. Cleavage at -Leu-Asp- of Mca-SEVNLDAEFK(Dnp) liberates the highly fluorescent 7-methoxycoumarin (Mca) fragment from the proximity quenching effect of the 2,4-dinitrophenyl (Dnp) internal quencher resulting in a large and easily detectable increase in fluorescence intensity.

Rhodamine-DHPE is a fluorescently labeled phosphatidylethanolamine lipid that labels phospholipid bilayers. Rhodamine-DHPE serves as a fluorescence quenching substrate and membrane stain. The fluorescence lifetime of Rhodamine-DHPE decreases significantly in the presence of Cu 2+-PS complexes. Rhodamine-DHPE effectively stains the membranes of human red blood cells and mouse fibroblasts, and supports lifetime-resolved imaging via pump-probe fluorescence microscopy .
