H-D-Val-Leu-Lys-AFC (Plasmin substrate) is a biological active peptide. (This is a fluorescent plasmin substrate, Abs/Em=380/500 nm.Plasmin belongs to the family of serine proteases. It plays a key role in fibrinolysis by dissolving fibrin in blood clots. Besides fibrinolysis, plasmin is also involved in such physiological and pathological processes as wound healing, liver repair, and the maintenance of liver homeostasis.)

Dnp-RPLALWRS	Fluorescent Dye	Others
Dnp-RPLALWRS is a fluorescent peptide substrate designed for human matrilysin (MMP-7). After enzymatic cleavage of Dnp-RPLALWRS 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 provides a sensitive and efficient detection method for kinetic studies and inhibitor screenin .

Dnp-RPLALWRS TFA	Fluorescent Dye	Others
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 .

HY-P4919

Mca-SEVNLDAEFK(Dnp)	Beta-secretase	Others
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.
