Performing a quantitative ELISA assay to detect human TNF-a
4 Aug 2019In this application note, Thermo Fisher Scientific describes a method for measuring human TNF-α using a quantitative enzyme-linked immunosorbent assay (ELISA) with the Multiskan FC microplate photometer. To demonstrate the instrument performance they utilize the Invitrogen human TNF-α ELISA kit along with the Thermo Scientific SkanIt software™ for microplate reader control and data analysis. The Thermo Scientific Wellwash Versa microplate washer is incorporated into the ELISA procedure to facilitate the microplate washing steps.

ELISAEnzyme-linked immunosorbent assays (ELISA), also known as enzyme immunoassays (EIA), are used for the detection and quantification of proteins, peptides and antibodies in a sample. ELISA often comes in kit format, with pre-selected antibody pairs to detect specific proteins or biomarkers of diseases such as diabetes and obesity, or cardiovascular and neurological disorders. Detection is made possible with chemiluminescent, fluorescent or colorimetric substrates and detection instruments such as microplate / ELISA readers. Other kits available include: Enzyme-linked immunospot (ELISPOT) assays for the quantification of protein-producing cells and chemiluminescent immunoassays (CLIA) kits.

The number of wells microplates contain can range from 6 to 3243 wells, with the 96-well format being the most commonly used. Microplates can come tailored for a range of applications including cell culture, PCR, filtration, storage, non-binding surface, protein crystallization, as well as pre-coated, deep well and normal Standard microplates. Additionally, options for microplate colors include clear , black, white or black with clear bottom and white with clear bottom for absorbance microplate reader applications.

Microplate readers are generally distinguished by their mode of detection. Types include absorbance, luminescence, fluorescence intensity, fluorescence polarization, TRF / FRET and multimode microplate readers. Microplate readers deliver a high throughput of samples by reading multiple wells simultaneously, with the 96-well format the most commonly used. As a result, microplate readers are often used in the drug discovery, bioassays, research and pharmaceutical industries for screening applications. Microplate loading can also be automated, with robotic microplate stackers to increase throughput.
