Used in research and development for respiratory syncytial virus (RSV) diagnostics and therapeutics. Serves as a reference standard in neutralization assays to evaluate the potency of candidate antibodies and vaccines. Employed in immunoassays to detect RSV fusion protein expression. Supports quality control in manufacturing of RSV-targeted biologics by providing a consistent benchmark for binding affinity and specificity. Also utilized in structural studies to understand antibody-antigen interactions critical for viral inhibition.
