Method Description

The galectin-3 assay is a diagnostic, quantitative 2-site manual enzyme-linked immunosorbent assay (ELISA) validated for use in human sera. The capture monoclonal antibody (rat IgG2a) is immobilized on 96-well plates, while the detection antibody utilizes a mouse monoclonal antibody that targets the human galectin-3 protein and is conjugated with horseradish peroxidase. This is an FDA 510K-cleared in vitro diagnostic device.(Package insert: BGM Galectin-3 Assay, BG Medicine, Inc. 05/2015)
