You Searched For: Assays

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.

Product Image-M172-1L

VWR®, Bradford protein assay, proteomics grade

Catalog Number: (M172-1L)
Supplier: VWR Chemicals
Description: 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.
UOM: 1 * 1 L

Product Image-1B1558-KIT

VWR® Fluorescent DNA Quantitation Kit

Catalog Number: (1B1558-KIT)
Supplier: VWR Chemicals
Description: Fluorescent DNA Quantitation Kit uses fluorescent bisBenzimide H33258 dye to bind to AT sequences of the minor groove of double-stranded DNA. In the assay, the sample is excited at 360 nm and when the dye binds to dsDNA an emission spectrum at 460 nm is produced.

Bicinchoninic acid disodium salt hydrate

Supplier: SIGMA-ALDRICH MICROSCOPY
Description: 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.

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.
