Static adhesion assay is a powerful tool that can be used to model the interactions between T lymphocytes and other cell types. Interactions are generated by injecting labeled T cells into wells coated with adhesion molecules, while a plate reader is used to quantify the number of adherent cells following serial washes.

Here we present two protocols, one for measuring the specific growth rate and the other for the cell-binding ability of rotavirus using the plaque assay and RT-qPCR. These protocols are available for confirming the differences in phenotypes between rotavirus strains.
FAQs
Reaching equilibrium allows the measured signal to represent the interaction after available binding sites have had time to engage. Under these conditions, researchers can compare retained material across samples rather than relying on a single time point. This makes the assay useful for estimating how strongly partners associate and for separating concentration-dependent binding responses from nonbinding material.
A concentration series shows how the retained signal changes as the amount of soluble binding partner increases. Comparing responses across concentrations helps researchers estimate affinity and identify whether the interaction is selective. It also provides information about binding capacity, because the response can be evaluated as available binding sites become increasingly occupied.
Affinity describes how strongly the two molecules associate, whereas specificity concerns whether the interaction favors the intended partner over other molecules. Binding capacity indicates how much partner the immobilized surface or scaffold can retain. Varying concentration and comparing binding responses allows these related but distinct properties to be assessed rather than treated as a single measurement.
Immobilization places one interaction partner on a defined surface or scaffold so that the other partner can be presented in solution and later separated from unbound material. This arrangement creates a consistent basis for quantifying retained signal. In bioengineering, the chosen surface or scaffold can therefore serve as the setting in which molecular recognition is evaluated.
The workflow begins by attaching one binding partner to a surface or scaffold, followed by exposure to a solution containing the other partner. The system is allowed to reach equilibrium, after which unbound material is removed. Researchers then quantify the retained signal and compare responses across concentrations or experimental samples to characterize the interaction.
These measurements can characterize receptor–ligand interactions, assess molecular recognition in biomaterials, and support biosensor development. They can also be applied when evaluating candidate therapeutics, where affinity, specificity, and capacity help describe how a molecule interacts with its intended binding partner. The same concentration-based approach supports comparisons among different binding systems.
Bioengineering frequently requires controlled interactions between molecules and designed surfaces, scaffolds, or devices. A Static Binding Assay provides quantitative information about whether those interactions occur selectively and how strongly material is retained. That information is relevant to engineering biomaterials, developing biosensors, studying receptor–ligand systems, and evaluating candidate therapeutics for intended molecular recognition.
