LBA-based protocols are expected to deliver sensitive, accurate, and precise analyte measurement Odorant Binding and Chemosensory Proteins. Chiara D'Onofrio, Paolo Pelosi, in Methods in Enzymology, 2020 Constitutive Activity in Receptors and Other Ligand Binding Assay Ligand binding assays (LBA) are most commonly applied for biotherapeutics, primarily based on a typical compound high molecular weight and/or specifics of the compound mode of action. From: Comprehensive Medicinal Chemistry III, 2017 Ligand Binding Assay Platforms: Radioimmunoassay (RIA) Enzyme immunoassay (EIA) Fluorescence immunoassay (FIA) Immunoradiometric assay (IRMA) Dissociation-enhanced lanthanide fluorescence immunoassay (DELFIA) Scintillation proximity assay (SPA) Branched Chain DNA Assay (bDNA) Ligand-binding assays (LBAs) stand as the cornerstone of support for definition of the pharmaco-kinetics and toxicokinetics of macromolecules, an area of burgeoning interest in the pharmaceutical industry.

A Flow Cytometry-based Assay to Identify Compounds - JoVE

The liquid phase ligand binding assay of Immunoprecipitation (IP) is a method that is used to purify or enrich a specific protein, or a group of proteins, using an antibody from a complex mixture. The extract of disrupted tissue or cells is mixed with an antibody against the antigen of interest, which produces the antigen-antibody complex. W Ligand‐binding assays (LBAs) or immunoassays are the analytical method of choice for pharmacokinetic (PK) and immunogenicity assessment for biopharmaceuticals.

With increasing use of ligand-binding assays (LBAs) in the pharmaceutical industry, the need to critically evaluate technical and regulatory issues related to the use of these technologies has increased greatly. This book fills that void and provides a reference text covering critical aspects of the development, validation, and implementation of LBAs in the drug development field. It includes The experimental protocol for binding assays is (somewhat deceptively) straightforward: (i) make a preparation containing the receptor, for instance, a membrane fraction, that can be divided into aliquots; (ii) select a suitable labelled ligand; (iii) incubate aliquots of the receptor preparation with chosen concentrations of the labelled ligand for a defined time at a defined temperature in a defined buffer; (iv) measure the bound and (sometimes or) free ligand concentration; (v) repeat Ligand‐binding assays (LBAs) or immunoassays are the analytical method of choice for pharmacokinetic (PK) and immunogenicity assessment for biopharmaceuticals. As pipelines for this class of drugs are expanding, immunoassays are revisited to address current scientific questions with this classic technology. Radioligand Binding Assays.
