Ligand Binding Assay Services Supporting End-to-End Drug Development

United Pharmaceuticals provides scientifically rigorous ligand binding assay services designed to support accurate decision-making throughout the drug development lifecycle. Our bioanalytical teams deliver customized immunoassay solutions that meet the technical, operational, and regulatory demands of modern pharmaceutical programs.

By integrating robust assay design with scalable laboratory workflows, we ensure consistent performance from early research through late-stage clinical development. Our ligand binding assays are developed to address complex biological questions while maintaining strict compliance with global regulatory expectations and internal quality systems.

 

Scientific Applications of Ligand Binding Assays

Our experienced bioanalytical scientists apply ligand binding assay methodologies across multiple stages of development, delivering reliable and reproducible data for a broad range of therapeutic areas, including metabolic disorders, neurological conditions, oncology, genetic diseases, and autoimmune indications.

We routinely work with diverse biological matrices such as plasma, serum, cerebrospinal fluid, and tissue samples obtained from multiple animal models and human studies. This flexibility allows United Pharmaceuticals to design fit-for-purpose assay strategies tailored to each program’s scientific objectives and regulatory pathway.
