You Searched For: Protein Assays

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.

Product Image-1B1301-KIT

VWR® Protein Precipitation Kit

Catalog Number: (1B1301-KIT)
Supplier: VWR Chemicals
Description: 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.

Conjugate stabilisers

Supplier: Rockland Immunochemicals
Description: Conjugate stabilisers are used with horseradish peroxidase (HRP) and calf intestinal alkaline phosphatase conjugated primary or secondary antibodies or other proteins or compounds in solution. The components of the stabiliser (proprietary) are unique and stabilise both the antibody and enzyme portions of the conjugate.

eFluxx-ID® multidrug resistance assay kit

Supplier: ENZO LIFE SCIENCES
Description: 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.

Protein assay kits, RED 660™

Supplier: G-Biosciences
Description: RED 660™ Protein Assay is a single reagent colorimetric assay that outperforms many commercial colorimetric assays, including Bradford and improved Coomassie/Bradford assays. It offers greater linearity, colour stability, and compatibility with detergents, reducing agents and other interfering agents compared to the Coomassie assays. The single, ready to use reagent allows for rapid analysis of total protein concentration and generates highly reproducible results.

PROTEOSTAT® protein aggregation assay

Catalog Number: (ENZOENZ51023KP050)
Supplier: ENZO LIFE SCIENCES
Description: PROTEOSTAT® Protein aggregation assay provides a simple, homogenous assay format for monitoring peptide and protein aggregation in solution. This is useful for defining optimal storage formulations for proteins, for screening of compounds that promote or inhibit protein aggregation and potentially for the sensitive measurement of molecular chaperone activity. The assay can be employed to streamline protein processing and formulation optimization procedures.
