Ligand receptor binding assay tutorial @595@

[kxwkebzParticipant]

A receptor ligand binding assay allows for the study and simple imaging of cell surface receptors for research and diagnostic applications. Receptor ligand binding is used in drug development applications to identify blocking antibodies or inhibitors that can modulate downstream signaling events, and is often used to screen for drugs that target hormone and neurotransmitter activity.

Justification For a Non-cell Based NAb Assay • Drug product : blocked ligand activity • Limited choice of cell lines expressing the receptor for ligand that was target for drug product • Only cell line available yielded at best 2-fold signal when treated with 100-200 ng/mL ligand A Guide to Simple and Informative Binding Assays. The aim of binding assays is to measure interactions between two molecules, such as a protein binding another protein, a small molecule, or a nucleic acid. Cooperativity means that binding of one ligand molecule to a receptor influences
Characterization of a Receptor Using a Radioligand. Analysis of saturation radioligand binding data. Saturation radioligand binding experiments measure specific radioligand binding at equilibrium at various concentrations of the radi-oligand. Analyze these data to determine receptor number and affinity.
Figure 1.Pharmacology of several adrenergic compounds at the alpha1A adrenergic receptor. The alpha1 antagonists WB 4101 and prazosin, alpha1 agonist cirazoline and endogenous ligand epinephrine were tested in a binding assay using [3 H]prazosin (0.1 nM) as a radioligand and membranes obtained from CHO cells transfected with the human alph1A receptor.
Receptor/ligand binding assay The culture medium containing the secreted AP fusion protein can be used directly to measure the presence or absence of a cell surface receptor (or ligand) of interest by assaying the AP activity bound to the cells. The secreted AP alone is used as a negative control.
The direct LRA allows for a quantification of ligand-receptor binding wit
