Fluorigenic method for the assay of proteinase activity with the use of 4-methylumbelliferyl-casein.
نویسندگان
چکیده
A method for the preparation of casein labelled with the 4-methylumbelliferyl fluorophore is described, and the product was used as a fluorigenic macromolecular substrate for a sensitive assay of the activity of proteinases. Nanogram quantities of trypsin, chymotrypsin, elastase and cathepsin D can be detected, but the substrate is unaffected by cathepsin B.

Curcumin (CUR) is the active curcuminoid with many physiological, biochemical, and pharmacological properties. Solubility and stability of CUR is the limiting factors for realizing its therapeutic potential. Bovine β-casein is an abundant milk protein that is highly amphiphilic and self-assembles into stable micellar nanoparticles in aqueous solution. β-Casein nanoparticle can solubilize CUR mo...
