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.

Catalogus nummer: (GAHK20-1KT)
Leverancier: Merck
Omschrijving: The Glucose (HK) Assay Kit is for the quantitative, enzymatic determination of glucose in food and other material.
UOM: 1 * 1 ST


Leverancier: SIGMA ALDRICH MICROSCOPY
Omschrijving: 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.

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.
UOM: 1 * 1 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.
UOM: 1 * 1 Kit


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.
UOM: 1 * 1 L

Leverancier: Biotium
Omschrijving: MTT, XTT, and resazurin are reduced by mitochondrial metabolic activity to yield coloured or fluorescent products, and thus are useful for and assaying cell viability and quantitating cell number. MTT and XTT are reduced to coloured formazin salts that can be measured by absorbance. MTT generates an insoluble formazin salt, requiring cell lysis before the absorbance can be measured, while XTT does not require cell lysis for measurement. Resazurin is a non-fluorescent blue dye that is reduced to the pink fluorescent compound resorufin, which can be measured by fluorescence or absorbance.
Catalogus nummer: (CAYM501700-96)
Leverancier: Cayman Chemical
Omschrijving: For the quantification of 2’3’-cGAMP in cell lysates.
UOM: 1 * 1 EA


Leverancier: Biotium
Omschrijving: Conjugates for probing cAMP receptors or measuring cGMP in immunoassays.

Catalogus nummer: (BSBTEK1433)
Leverancier: Boster Bio
Omschrijving: Sandwich high sensitivity ELISA kit for quantitative detection of mouse EGFR.
UOM: 1 * 1 Kit


Catalogus nummer: (CAYM10006910-96)
Leverancier: Cayman Chemical
Omschrijving: HIF-1α Transcription Factor Assay Kit is a sensitive, non radioactive method for detecting HIF-1α from whole cell lysates.
UOM: 1 * 1 Kit


Leverancier: Biotium
Omschrijving: TUNEL (terminal deoxynucleotidyl transferase (TdT) mediated dUTP nick-end labeling) is highly selective for the detection of apoptotic cells, but not necrotic cells or cells with DNA strand breaks resulting from irradiation or drug treatment. In this assay, TdT enzyme catalyses the addition of labeled dUTP to the 3’ ends of cleaved DNA fragments. Fluorescent dye-conjugated dUTP can be used for direct detection of fragmented DNA by fluorescence microscopy or flow cytometry.

Leverancier: Cayman Chemical
Omschrijving: A competitive assay for the quantification of cortisol in urine, plasma, and other sample matrices.

Leverancier: Cayman Chemical
Omschrijving: 8-Isoprostane Express ELISA kit is a competitive assay for the quantification of 8-isoprostane in plasma, serum, urine, whole blood, tissue culture supernatants, and other sample matrices.

Leverancier: G-Biosciences
Omschrijving: CB-X™ Protein Assay is a Coomassie dye based protein assay based on the Bradford Protein Assay. For protein samples in simple, uncomplicated aqueous buffers CB-X™ is a highly sensitive, single reagent assay that can be performed in 5 minutes. For complicated protein samples, CB-X™ Protein Assay is supplied with reagents to clean up the samples and remove all reagents and chemicals that interfere with accurate protein estimation in a single step. These reagents include detergents, chaotropes, reducing agents, alkylating agents, sugars, high salt concentrations, buffering agents and chelating agents. The clean up stage and subsequent protein assay is performed in a single tube to ensure no protein loss and to maintain the accuracy of the assay.

Leverancier: Biotium
Omschrijving: CellBrite-kits zijn ontworpen om celcytoplasmamembranen te labelen met een fluorescerende membraankleurstof die vooraf is opgelost als een geoptimaliseerde kleuroplossing. Door CellBrite-membraankleuringen te combineren, is het mogelijk om meerdere celpopulaties te labelen met onderscheidende kleuren, een mogelijkheid die nuttig is voor het bestuderen van cel-celinteracties.
Leverancier: ENZO LIFE SCIENCES
Omschrijving: The PROTEOSTAT® PDI assay kit provides a simple, homogenous assay for screening modulators of PDI enzymatic activity. This is accomplished by monitoring PDI-catalyzed reduction of insulin in the presence of Dithiothreitol (DTT), resulting in the formation of insulin aggregates which then bind avidly to the red-emitting fluorogenic PROTEOSTAT® PDI detection dye.
