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.

VWR® Fluorescent DNA Quantitation Kit

Catalogus nummer: (1B1558-KIT)
Leverancier: VWR Chemicals
Omschrijving: 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.

Product Image-M172-1L

VWR®, Bradford protein assay, proteomics grade

Catalogus nummer: (M172-1L)
Leverancier: VWR Chemicals
Omschrijving: 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-1B1301-KIT

VWR® Protein Precipitation Kit

Catalogus nummer: (1B1301-KIT)
Leverancier: VWR Chemicals
Omschrijving: 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.

Calcineurin phosphatase assay kit

Catalogus nummer: (ENZOBMLAK8040001)
Leverancier: ENZO LIFE SCIENCES
Omschrijving: This colorimetric kit is designed for inhibitor screening or kinetic assay of recombinant Calcineurin. Activity is determined using the RII phosphopeptide substrate, the most efficient and selective peptide known for calcineurin, and detection of free phosphate released is based on the classic malachite green assay.

FLUOR DE LYS® HDAC fluorometric activity assay kit

Catalogus nummer: (ENZOBMLAK5000001)
Leverancier: ENZO LIFE SCIENCES
Omschrijving: The FLUOR DE LYS® HDAC fluorometric activity assay kit is a sensitive and convenient alternative to protocols utilizing radiolabeled, acetylated histones or peptide/HPLC methods for the assay of histone deacetylases. It is based on the unique FLUOR DE LYS® (Fluorimetric Histone deAcetylaseLysyl) substrate and developer combination and provides an assay that can be carried out in two simple mixing steps, all on the same 96-well plate. Histone deacetylase inhibitors have shown promise as anti-tumor agents and naturally this has stimulated interest in the screening of compounds for HDAC inhibition.

FLUOR DE LYS® HDAC8 fluorometric drug discovery kit

Catalogus nummer: (ENZOBMLAK5180001)
Leverancier: ENZO LIFE SCIENCES
Omschrijving: A Fluor-de-Lys® fluorescent assay system. The HDAC8 Fluorescent Activity Assay/Drug Discovery Kit is a complete assay system designed to measure the lysyl deacetylase activity of the recombinant human HDAC8 included in the kit. The kit is ideal for chemical library screening for candidate inhibitors or activators or kinetic assay of the enzyme under varying conditions. The Fluor de Lys® HDAC8 assay is based on the Fluor de Lys® Substrate and Fluor de Lys® Developer combination. The assay procedure has two steps. First, the Fluor de Lys® Substrate, which comprises an acetylated lysine side chain, is incubated with HDAC6. Deacetylation of the substrate sensitizes the substrate so that, in the second step, treatment with the Fluor de Lys®Developer produces a fluorophore.

FLUOR DE LYS® HDAC fluorometric cellular activity assay kit

Catalogus nummer: (ENZOBMLAK5030001)
Leverancier: ENZO LIFE SCIENCES
Omschrijving: The HDAC fluorometric cellular activity assay allows the determination of deacetylase activity within an undisturbed cellular environment and provides accurate activity information that is reflective of endogenous regulation. It also allows the study of the effects of upstream regulators on deacetylase activity and the detection of inhibitors or activators that act indirectly to affect deacetylase activity.
