The CaptureSelect TSH Ligand Leakage ELISA is designed to detect possible leached ligand of thyroid-stimulating hormone (TSH) purified using CaptureSelect TSH Affinity Matrix. The ligand, a 14-kD recombinant protein, is covalently coupled for high chemical stability and low leakage. Even when covalently attached, small amounts of the affinity ligand can leach off of the chromatography support and co-elute with the protein. This ELISA provides typical sensitivity and accurate quantitation of possible leached ligand greater than or equal to 1 ng/mL. The CaptureSelect TSH Ligand Leakage ELISA can be used as a tool to aid in optimal purification process development and in routine quality control of in-process streams as well as final product.
