Ligand binding assays in the area of bioanalysis is not an independent discipline; therefore our scientists work closely with our immunogenicity, pharmacokinetic, and statistical specialists to deliver the appropriate solutions and interpretations applicable to your molecule and your program. Ligand-binding assays (LBA) is the industry accepted method for quantification of proteins, antibodies, DNA, ribonucleic acids, biosimilars and other large molecules in pharmacokinetic (PK), toxicokinetic (TK), pharmacodynamic (PD) and immunogenicity studies during preclinical and clinical development. Radioligand binding assays A radioactively labeled ligand is applied in this assay to detect its binding to a target. Currently, radioligand binding assays are mainly used for membrane-bound molecules, such as G protein-coupled receptors like angiotensin II type 1 receptor [ 23] or apelin receptor [ 24 ]. Ligand Binding Our ligand binding group offers support for Immunogenicity, PD, PK, BE, and Biosimilar studies for both preclinical and clinical stages of drug development. We have nearly a decade of experience with small and large molecules, such as oligonucleotides, small peptides, chemical elements, proteins, bi-specific antibodies Radioactive ligands are commonly used to measure ligand binding to receptors. In this assay, you will measure binding of a radiolabeled ligand to cells or cell membranes containing a receptor of interest.

In this assay, you will measure binding of a radiolabeled ligand to cells or cell membranes containing a receptor of interest. Both whole cells and cell membranes can be used for this assay.

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

2020-07-24 · Ligand binding assays are effectively applied for both studies aiming to understand the regulation of biological functions and the research focused on developing new drugs which are strongly based on the determination of binding affinity and efficacy. Our Ligand binding assay types: Immunogenicity assays: ADA: screening, confirmatory and titration; nAb by non-cell based and cell-based assays; Quantification methods using various platforms; Hybridization ELISA/ECLIA of various types (ligation, dual hybridization) Functional cell-based assays; Biomarkers Abstract. Purpose: With this publication a subcommittee of the AAPS Ligand Binding Assay Bioanalytical Focus Group (LBABFG) makes recommendations for the development, validation, and implementation of ligand binding assays (LBAs) that are intended to support pharmacokinetic and toxicokinetic assessments of macromolecules.

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.

Yet they are not fool-proof and require the same level of validation as chromatographic methods. To learn more about how to systematically leverage the many benefits of M&S across a drug development program, read this white paper.
