Accurately quantifying total protein concentration is a key to most experiments and is often necessary for isolation, separation, and analysis of proteins by biochemical methods. When it is necessary to determine the total protein concentration in a sample, one of the first factors to consider is the selection of a protein assay method. These choices are typically based upon the compatibility of the method with the samples to be assayed. Each method has its own advantages and disadvantages.

ADAM17 Fluorometric Drug Discovery Kit, Enzo Life Sciences
Supplier: Enzo Life Sciences
Designed to screen ADAM17 (TACE) inhibitors using a quenched fluorogenic peptide. The ADAM17 Fluorometric (also known as fluorimetric) Drug Discovery Kit is a complete assay system designed to screen ADAM17 (TACE) inhibitors using a quenched fluorogenic peptide: Mca-PLAQAV-Dpa-RSSSR-NH2. Mca fluorescence is quenched by the Dpa group until cleavage by proteases separates the two moieties. The assays are performed in a convenient 96-well microplate format. The kit is useful to screen inhibitors of ADAM17, a potential therapeutic target. The compound GM6001 is also included as a prototypic control inhibitor.
