Key Components in Lateral Flow Assay Systems
Lateral flow assays consist of several key components, each of which plays a vital role in ensuring the accuracy and effectiveness of the test. These components include:
- Sample Pad: The sample pad is where the biological sample (e.g., blood, saliva, urine) is initially applied. This component is designed to allow the sample to flow across the device and interact with the conjugate pad. The sample pad must be chemically treated to ensure the optimal flow of the sample.
- Conjugate Pad: The conjugate pad contains antibodies or antigens that are conjugated (bound) to colored particles, such as gold nanoparticles or latex beads. These particles bind to the target analyte in the sample, helping to indicate its presence or absence. The conjugate pad is critical in ensuring the sensitivity and specificity of the test.
- Nitrocellulose Membrane: The nitrocellulose membrane is the key area of the device where the results appear. As the sample and conjugate move along the membrane, they encounter test and control lines. If the target analyte is present, it will bind to the antibodies or antigens on the test line, producing a visible signal, such as a colored line or spot.
- Absorbent Pad: The absorbent pad is located at the end of the device and serves to absorb excess fluid after the sample has flowed through the membrane. This ensures that the sample moves along the device at the correct speed and that the reaction is completed properly.
