CaptureSelect™ GCSFSelect Leakage ELISA

CaptureSelect GCSFSelect Leakage ELISA is designed to detect possible leached ligand of human GCSF purified using GCSFSelect affinity resin (Cytiva). Even when covalently attached, small amounts of the IgSelect affinity ligand can leach off of the chromatography support and co-elute with the antibody.

This ELISA provides typical sensitivity and accurate quantitation of possible leached ligand greater than or equal to 1 ng/mL. The CaptureSelect GCSFSelect 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.
