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 behaviour than what can be handled by traditional chemical analysis and titration.

Product Image-VWRC1B1301-KIT

VWR® Protein Precipitation Kit

Catalog Number: (VWRC1B1301-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.

Product Image-VWRCM172-1L

VWR®, Bradford protein assay, proteomics grade

Catalog Number: (VWRCM172-1L)
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.

Product Image-VWRC1B1558-KIT

VWR® Fluorescent DNA Quantitation Kit

Catalog Number: (VWRC1B1558-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.

BCA protein assay kit

Catalog Number: (ALFAJ63283.QA)
Supplier: Thermo Scientific
Supplier Article Number:: J63283.QA
Description: BCA Protein Assay Kit can be used to measure very dilute protein concentrations in very small sample volumes. The kit accurately measures protein concentrations from 0,5 to 30 μg/ml in tube assays and 1 to 20 μg/ml in 96- or 384-well plate assays. It is used for studying protein:protein interactions, measuring column fractions after affinity chromatography, estimating percent recovery of membrane proteins from cell extracts and high-throughput screening of fusion proteins.

3,3',5,5'-Tetramethylbenzidine, MP Biomedicals

Supplier: MP Biomedicals
Description: 3,3',5,5'-Tetramethylbenzidine (TMB) for ELISA-based applications. Molecular weight: 240,3 g/mol.

Image Unavailable-ICNA0210072650

Histone, from calf thymus, MP Biomedicals

Supplier: MP Biomedicals
Description: Histones are soluble in water (10 mg/ml) or 0,5 N HCl (10 mg/ml), yielding a clear to hazy solution depending on the fraction. They are soluble in 6 M urea (4 to 10 mg/ml), but this will denature the histones.

Protein quantitation assay kits, Non-Interfering™ (NI™) Protein Assay

Catalog Number: (GENO786-005)
Supplier: G-Biosciences
Supplier Article Number:: 786-005
Description: A highly sensitive colorimetric protein assay that overcomes interference of common laboratory agents present in protein solutions and shows minimal protein-to-protein variation. The assay is unaffected by the presence of common laboratory agents such as reducing agents, chelating agents, detergents, amines, sugars, chaotropes, salts, drugs, antibiotics, cobalt, and others.
