Reagent Kit: The ARCHITECT Galectin-3 assay is a chemiluminescent microparticle immunoassay (CMIA) for the quantitative determination of galectin-3 in human serum and EDTA plasma. The ARCHITECT Galectin-3 assay may be used in conjunction with clinical evaluation as an aid in assessing the prognosis of patients diagnosed with chronic heart failure (HF). The ARCHITECT Galectin-3 assay is used with the ARCHITECT i System with STAT protocol capability. Calibrators: The ARCHITECT Galectin-3 Calibrators are for the calibration of the ARCHITECT i System when used for the quantitative determination of galectin-3 in human serum and EDTA plasma. Controls: The ARCHITECT Galectin-3 Controls are for the verification of the ARCHITECT i System when used for the quantitative determination of galectin-3 in human serum and EDTA plasma.

The ARCHITECT Galectin-3 assay is a two-step immunoassay for the guantitative determination of galectin-3 in human serum or EDTA plasma using CMIA technology with flexible assay protocols, referred to as Chemiflex. In the first step, sample and M3/38 anti-galectin-3 coated paramagnetic microparticles are combined. Galectin-3 present in the sample binds to the anti-galecin-3 coated microparticles. After washing, 87B5 anti-galectin-3 acridinium-labeled conjugate is added to create a reaction mixture in the second step. Following another wash cycle, pre-trigger solutions are added to the reaction mixture. The resulting chemiluminescent reaction is measured as relative light units (RLUs). A direct relationship exists between the amount of galectin-3 in the sample and the RLUs detected by the ARCHITECT i System optics. The kit is composed of the following: ARCHITECT Galectin-3 Reagent Kit (5P03) ARCHITECT Galectin-3 Calibrators (5P03-01) ARCHITECT Galectin-3 Controls (5P03-10)

BGM Galectin-3 is an in vitro diagnostic device that quantitatively measures galectin-3 in serum or EDTA-plasma by enzyme-linked immunosorbant assay (ELISA) on a microtiter plate platform to be used in conjunction with clinical evaluation as an aid in assessing prognosis of patients diagnosed with chronic heart failure (HF). BGM Galectin-3 is indicated for prescription use only.

BGM Galectin-3 is a microtiter plate-based sandwich enzyme-linked immunosorbant assay (ELISA) for the quantitative determination of galectin-3 levels in human serum and plasma. BGM Galectin-3 consists of a rat monoclonal anti-mouse galectin-3 antibody coated microtiter plate serving as the solid phase capture antibody and a horseradish peroxidase (HRP)-labeled mouse monoclonal anti-human galectin-3 antibody functioning as the liquid phase tracer antibody for detecting bound galectin-3. In the testing procedure, galectin-3 in the standard, control, or patient specimen binds to the immobilized capture antibody; after a wash step, bound galectin-3 is detected by the addition of HRP-labeled anti-galectin-3 antibody. Following a second wash step, the presence of bound galectin-3 is demonstrated by an enzymatic blue color development resulting from the addition of tetramethylbenzidene (TMB) solution as the substrate. Color development is stopped by adding sulfuric acid, changing the color to yellow. Color intensity is read at an absorbance of 450 nm using a colorimetric reader. The absorbance is proportional to the galectin-3 levels in the samples, and test results of the samples are determined using a calibration curve derived from the standards. BGM Galectin-3 contains the microtiter plate, reagents, assayed quality control materials and standards required to perform analyses on serum or EDTA-plasma samples.
