An assay is an investigative procedure in laboratory medicine, pharmacology, environmental biology, and molecular biology for qualitatively assessing or quantitatively measuring the presence or functional activity of the analyte, or the entity being targeted by the assay. Generally, assays involve biological materials or phenomena which tend to be intrinsically more complex in composition or in behavior than what can be handled by traditional chemical analysis and titration.
Bicinchoninic acid disodium salt hydrate
Supplier: SIGMA ALDRICH MICROSCOPY
Bicinchoninic acid is used for the determination of protein concentration. It is responsible for the making of intense purple complex with cuprous ion (Cu+) in the presence of alkaline conditions. The amount of Cu+ is in relation with the protein concentration.

VWR®, Bradford protein assay, proteomics grade
Supplier: VWR Chemicals
The Bradford protein assay is the preferred colorimetric assay for quantifying total protein concentration. Based upon complex formation between basic and aromatic amino acid residues with Coomassie® Brilliant Blue G-250 dye, the Bradford method is easier, faster, and more sensitive than the Lowry method.

VWR® Protein Precipitation Kit
Supplier: VWR Chemicals
The Protein Precipitation Kit utilises a simple trichloroacetic acid (TCA) based method to precipitate proteins in complex mixtures. Only protein in the sample is pelleted, while interfering salts and surfactants remain in the supernatant. A gentle acetone wash removes TCA and co-precipitants allowing the end-user to recover the protein in a small volume of buffer.
