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.

Bicinchoninic acid disodium salt hydrate

Fornecedor: SIGMA ALDRICH MICROSCOPY
Descrição: 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® Protein Precipitation Kit

Código de Artigo: (1B1301-KIT)
Fornecedor: VWR Chemicals
Descrição: 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.

eFluxx-ID® multidrug resistance assay kit

Fornecedor: ENZO LIFE SCIENCES
Descrição: The EFLUXX-ID® Multidrug Resistance Assay Kit allows for functional detection of all three clinically relevant ABC transporter proteins MDR1 (p-glycoprotein), MRP1/2, and BCRP. The assay uses a hydrophobic, non-fluorescent compound that readily penetrates the cell membrane, where it is hydrolyzed to a hydrophilic fluorescent dye by intracellular esterases.
