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.

Cyclic-AMP fluorescent assay kits, CatchPoint™

Proveedor: MOLECULAR DEVICES
Descripción: 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.

ELISA kits, femtoELISA™

Proveedor: G-Biosciences
Descripción: The femtoELISA™ kits utilise a non animal protein blocker, NAP-BLOCKER™ that minimises cross-reactivity with researcher's antigens and antibodies. For the detection of HRP, an improved, ultra sensitive, non volatile, stable colorimetric substrate based on tetramethyl benzidine (TMB) is supplied. Reagent does not require hydrogen peroxide that can have detrimental effects on many biological factors, which may ultimately affect the assays.

CFDA SE Cell proliferation assay kit

Numero del catalogo: (30050.)
Proveedor: Biotium
Descripción: 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.
