Answer:
To determine the effect of toxin binding, you perform a Competitive Binding Experiment
Explanation:
Competitive binding experiments are very relevant when matters relating to cellular and or molecular toxicity are concerned.
They are used to determine the binding of a single concentration of labeled ligand in the presence of various concentrations of unlabeled ligand.
They are important because:
1. Validate a direct binding assay
2. Confirm whether or not a drug binds to the receptor
3. determine and explore how low-affinity drugs and receptors interact and it's resultant effects
