What is an ELISA Test Kit?


An ELISA test kit consists of all the necessary components to perform an ELISA assay, including microplate wells, assay buffers, standards, controls, and often a detailed protocol. The core principle of the ELISA technique is based on the specific binding between an antigen and an antibody. By leveraging enzyme-linked antibodies, ELISA tests can quantify the presence of specific biomarkers in a sample.

### Types of ELISA

There are several variations of the ELISA technique, each tailored to specific applications:

1. **Direct ELISA**: This method involves immobilizing an antigen on a microplate and then adding an enzyme-linked antibody directly to quantify the antigen.

2. **Indirect ELISA**: In this method, the antigen is coated on the plate, and a primary antibody is added first followed by an enzyme-linked secondary antibody that binds to the primary antibody, providing enhanced sensitivity.

3. **Sandwich ELISA**: This is one of the most commonly used formats, where an antibody is coated on the plate, followed by the sample (which contains the target antigen) and a second enzyme-linked antibody, allowing for specific detection of the antigen.

4. **Competitive ELISA**: This type measures the concentration of an antigen by observing the competition between the sample antigen and a fixed amount of enzyme-linked antigen for a specific antibody. https://mzfoodtest.com/
