Principles of Elisa

At the heart of Elisa lies a binding between antibodies and their target molecules. The process begins as the capture antibody delicately immobilizes onto the microplate surface. This immobilization creates a solid-phase antibody production service.

With the stage set, the protagonist, the sample containing the analyte, is added to the microplate. A flurry of activity unfolds as the target molecules seek and bind to the waiting capture antibody, their union sealed with molecular precision.

The Elisa assay orchestrates the binding of antibodies and their targets, an exquisite interplay that fuels the scientific quest for knowledge. Once the process climaxes, a cleansing wave sweeps through, washing away the unbound components and leaving only the core components behind. It's a captivating journey that unravels the secrets within the samples, helping with detection and discovery.

As the Elisa process unfolds, the next step is the detection antibody linked to an enzyme. With its keen eye for a different epitope on the target molecule, this antibody forms a complete sandwich-like structure.

It binds to its designated spot, forming a trinity of capture antibody, analyte, and detection antibody. With a sweep, the unbound detection antibodies are washed away, leaving behind only the essential components of the narrative.

The last step involves adding a substrate tailor-made for the enzyme. This catalyst sparks a reaction that creates a mesmerizing display of change. A molecular interaction unfolds, culminating in a color change. The color of the microplate undergoes a metamorphosis that mirrors the presence and quantity of the analyte in the sample.
