ELISA (Enzyme-Linked Immunosorbent Assay)

For Peptide, Antibody, Hormone, and Protein Detection

Enzyme-linked immunosorbent assays (ELISA) are the most common method for ligand binding assays, and are a core competency for the BioAgilytix team. We use ELISA in both its original and automation-powered forms as a fast, reliable, and cost-effective platform for analyte quantification of specific assays.

How the ELISA Method Works

The ELISA method is designed for detecting and quantifying substances such as peptides, proteins, antibodies and hormones, and is typically performed on a 96-well plate. Using ELISA, detection is completed by assessing the conjugated enzyme activity via incubation with a substrate to produce a measurable signal.

The binding and immobilization of reagents done through ELISA makes it easy to separate bound from non-bound material during the assay, and wash away non-specifically bound materials to measure specific analytes.

The ELISA technique was originally developed in the 1970s, when it was created as a replacement for traditional radioimmunoassay methods. More recently however, the ELISA method has been paired with laboratory automation techniques to dramatically improve throughput and sensitivity. Such advancements include automated plate washing and automated readouts.

Ideal ELISA Applications: For Diverse Large Molecule Study Requirements

The ELISA method is one of the most diverse available, with applications throughout health care and large molecule laboratory science. The platform comes in a variety of mechanisms, including direct, indirect, sandwich, competitive and ELISPOT, each with its own optimal applications.

As a bioanalytical laboratory that harnesses a variety of platforms, BioAgilytix most frequently leverages ELISA in our work with biomarkers, immunogenicity, pharmacokinetics (PK), and cell-based assays. ELISA can be leveraged in a multitude of research areas, including oncology, cardiovascular, neuroscience, and stem cell.

Key ELISA Benefits: High Precision and Wide Dynamic Range

Even after more than 40 years of widespread use, the ELISA method is still widely regarded for its many advantages. Aside from its original benefit of not requiring radioisotopes or radiation-measurement equipment and its use of fluorescence, ELISAs offer high sensitivity, specificity, adaptability and reliability when compared to other techniques.

The ELISA plate will passively bind antibodies and proteins, and is then developed by adding an enzymatic substrate to produce a visible signal that indicates the quantity of antigen is captured on a plate and followed by incubation with the detection antibody.

This binding and immobilization of reagents makes it easy to separate bound from nonbound material during the assay, and wash away nonspecifically bound materials to measure specific analytes.
