Aspartate aminotransferase chemistry reagents, R1: 60ml×2 R2: 15ml×2

A liquid-stable, two-reagent kit for the determination of aspartate aminotransferase (AST) activity in serum or plasma. The L-aspartate substrate method with NADH-coupled malate dehydrogenase detection supports sensitive kinetic measurement on open-channel chemistry analyzers. Each lot is validated for linearity, calibration performance, and on-board stability. The reagent is packaged in ready-to-use liquid form for efficient bench workflow. Supplied with R1 (60 mL × 2) and R2 (15 mL × 2).
