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.

Leverancier: Biotium
Omschrijving: RedDot™2 is a far-red cell membrane-impermeant nuclear dye similar to Draq7™. Ideal for staining the nuclei of dead or fixed and permeabilized cells with minimal cytoplasmic RNA staining.
Leverancier: Biosensis
Omschrijving: The Biosensis NGF Rapid™ enzyme-linked immunosorbent assay (ELISA) kit is a sandwich ELISA that allows the quantification of mouse NGF in less than 3 hours in cell culture supernatants and brain extracts only if used as directed.

Leverancier: Molecular Devices
Omschrijving: CatchPoint™ cAMP Fluorescent Assay Kit measures cAMP levels via a competitive immunoassay format. Cell signaling via G protein-coupled receptors (GPCRs) can be assessed by monitoring the downstream effectors calcium or Cyclic AMP (cAMP). Monitoring levels of cAMP, a second messenger produced in response to activation of adenylate cyclase, is one of the most common ways to screen for agonists and antagonists of GPCRs.

Leverancier: Molecular Devices
Omschrijving: SpectraMax® Quant™ dsDNA Assay kits are designed for fluorescence-based dsDNA quantitation across a broad range of concentrations.

Leverancier: Molecular Devices
Omschrijving: EarlyTox™ Cell Viability Assay Kits are a family of fluorescence-based reagents for the assessment of cell viability, cell proliferation, and various apoptosis events using mammalian cells. Optimised for use with microplate readers, these assay kits employ a no-wash, homogeneous assay protocol that enables characterisation of a full concentration-response profile of test compounds.

Catalogus nummer: (CAYM700460-192)
Leverancier: Cayman Chemical
Omschrijving: For the measurement of creatinine levels in plasma and serum.
UOM: 1 * 1 EA


Catalogus nummer: (CAYM600610-192)
Leverancier: Cayman Chemical
Omschrijving: A convenient all-in-one tool to measure neutrophil elastase activity.
UOM: 1 * 1 EA


Catalogus nummer: (23006.)
Leverancier: Biotium
Omschrijving: Flow Cytometry Fixation/Permeabilisation Kit contains optimally formulated buffers for fixation and permeabilisation of suspension cells for immunofluorescence staining of intracellular antigens for analysis by flow cytometry. The bufffers are also available separately.
UOM: 1 * 1 EA

Catalogus nummer: (30050.)
Leverancier: Biotium
Omschrijving: Cell proliferation dyes diffuse passively into cells and covalently label intracellular proteins, resulting in long term cell labelling. They are non-fluorescent until they are hydrolysed by intracellular esterase's. The dyes then react with intracellular amines forming fluorescent conjugates that are retained in the cell. Immediately after staining, a single, bright fluorescent population will be detected by flow cytometry. With each cell division, daughter cells inherit roughly half of the fluorescent label, allowing the number of cell divisions that occur after labelling to be detected by the appearance of successively dimmer fluorescent peaks on a flow cytometry histogram compared to cells analysed immediately after staining. Staining is formaldehyde fixable.
UOM: 1 * 1 Kit


Leverancier: G-Biosciences
Omschrijving: The Bicinchoninic Acid (BCA) Protein Assay is a highly sensitive colorimetric assay that is compatible with detergent solubilised protein solutions, however is dramatically affected by the presence of reducing agents, including DTT, ß-mercaptoethanol and TCEP.
Leverancier: G-Biosciences
Omschrijving: 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.
