Description
After incorporation of EdU (a modified thymidine analogue) into newly synthesize DNA, horse radish peroxidase (HRP) is covalently attached via the highly specific click reaction. Amplex UltraRed Reagent, an HRP substrate, is then added and the resulting fluorescence signal detected. Because of the highly specific attachment of HRP to EdU, this assay results in highly sensitive and reliable measurement of mammalian cell proliferation in a microplate format.
Click-iT EdU Proliferation Assay for Microplates features include:
• Improved performance—direct conjugation of HRP to incorporated EdU improves assay sensitivity and accuracy
• Increased reliability—assay format results in low well-to-well variability
• Simplified protocol—results in reduced time to data; easier to follow protocol
• Multiplex enabled—assay can be easily multiplexed with other cell health reagents resulting in more data per sample
Measuring cell proliferation is a fundamental method of assessing cell health, determining genotoxicity, and evaluating anti-cancer drugs. The most accurate method of measuring proliferation is by direct detection of DNA synthesis. Originally this was accomplished through incorporation of a radioactive nucleoside (e.g., 3H-thymidine). This method was replaced by antibody-based detection of the nucleoside analog bromo-deoxyuridine (BrdU). After incorporation of BrdU into the newly synthesized DNA, denaturation is required to expose the BrdU molecules to the anti-BrdU antibody. The denaturation involves harsh methods (HCl, heat, or enzymes) and is time consuming and difficult to perform consistently.
The Click-iT EdU Proliferation Assay is an alternative to the BrdU assay. The nucleoside analog EdU (5-ethynyl-2´-deoxyuridine) is added to live cells and incorporated into DNA during active DNA synthesis. The incorporated EdU contains an alkyne group which is covalently joined to the azide group present in HRP using a highly specific copper-catalyzed covalent reaction ('click reaction'). Amplex UltraRed Reagent is then added and its conversion by HRP into a highly fluorescent product is recorded using a fluorescence microplate reader (excitation: 568, emission: 585 nm). With a high extinction coefficient, good quantum efficiency, and resistance to auto-oxidation, Amplex UltraRed Reagent delivers higher sensitivity and a broader assay range than other fluorogenic or colorimetric HRP substrates. It also offers versatility through detection by either fluorescence or absorbance measurement.
