CaptureSelect™ IgE Ligand Leakage ELISA

CaptureSelect IgE affinity ligand is a 13-kD recombinant protein, expressed in yeast and covalently coupled to a chromatography matrix for high chemical stability and low leakage. During the chromatography process, small amounts of 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 IgE 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.
