Acth (1-4) acetate is the ACTH N-terminal tetrapeptide.

Acth (1-4) is the ACTH N-terminal tetrapeptide.

Bz-Nle-Lys-Arg-Arg-AMC is a fluorescent tetrapeptide substrate for the quantitative detection of dengue virus (DV) NS2B-NS3 protease, yellow fever virus (YFV) NS3 protease and Zika virus NS3 protease activities. The rate of release of the cleavage product of the protease, AMC (7-amino-4-methylcoumarin), was observed by hydrolysis reaction to calculate the enzyme activity, with excitation emission maxima at 340-360 440-460 nm, respectively.

FMRF (Phe-Met-Arg-Phe) is a tetrapeptide comprising four amino acid residues.

Acetyl tetrapeptide-2 is a skin conditioner, by soothing and nourishing the skin through similar mechanisms as other peptides.

Acetyl tetrapeptide-2 Acetate is most commonly used as a skin conditioner. Acetyl tetrapeptide-2 Acetate is done by compensating for hormone loss in the skin, especially collagen, providing somewhat of a plumping effect to the skin.
