    Procedure using 96-well plate
    1.Samples and controls. Transfer 20 µL of each sample to separate wells. Also, for each assay plate, include two wells with 20 µL distilled water to be used for the NADH Standard and Blank. Keep plate at the desired temperature (e.g. 37°C).
    2.Prepare Working Reagent for Sample and Standard wells by mixing for each well: 200 µL Assay Buffer, 5 µL Cosubstrate, 1 µL LDH and 4 µL NADH. Warm to desired temperature (e.g. 37°C). Prepare Blank Reagent for the Blank well by mixing: 200 µL Assay Buffer, 5 µL Cosubstrate, 1 µL LDH and 4 µL H2O. Warm to desired temperature (e.g. 37°C).
    3. Add 200 µL Working Reagent to each Sample and Standard well, and 200 µL Blank Reagent to the Blank well. Immediately tap plate to mix, incubate at the desired temperature and read OD340nm at 5 min and at 10 min. Alternatively, record kinetics at 340 nm.

    Procedure using cuvettes
    1. For each assay, include one Standard and one Blank control. For each Sample and Standard, prepare Working Reagent by mixing 1000 µL Assay Buffer, 25 µL Cosubstrate, 5 µL Enzyme Mix and 20 µL NADH. Transfer 1000 µL Working Reagent to each sample cuvette and standard cuvette. Warm to desired temperature (e.g. 37°C). For Blank control, mix 1000 µL Assay Buffer, 25 µL Cosubstrate, 5 µL Enzyme Mix and 20 µL H2O. Transfer 1000 µL Reagent to the Blank control cuvette. Warm to desired temperature (e.g. 37°C).
    2. Prewarm sample to the desired temperature. Add 100 µL Sample to the Sample Cuvette. Transfer 100 µL H2O to the Standard cuvette and to Blank Control cuvette, respectively. Mix immediately.
    3. Read OD340nm at 5 min and 10 min. Alternatively, record kinetics at 340 nm.
    Préparation des réactifs

    Equilibrate all components to room temperature. Mix assay buffer well by vigorous shaking. Keep thawed enzyme on ice. Assays can be performed at 37°C or at room temperature. Prior to assay, bring the working reagents, microplate and spectrophotometer to the desired temperature. Assay is compatible with serum or plasma (heparin, EDTA). Samples should be clear and free of particles or precipitates. Hemolyzed samples should not be used.

    Sujet
    Quantitative determination of Alanine transaminase activity at 340nm.
    Procedure: 10 min.

    Alanine Transaminase (ALT), also known as serum alanine aminotransferase (ALAT) or pyruvic transaminase (SGPT), facilitates the conversion of alanine and -ketoglutarate to pyruvate and glutamate. ALT plays an important role in gluconeogenesis and amino acid metabolism. ALT is found mainly in the liver, and, to a lesser extent, in kidney, heart, muscle, and pancreas tissues. Normal serum levels of ALT are low, and increased serum ALT activity is widely used as a marker for liver damage. Simple, direct and automation-ready procedures for measuring ALT activity find wide applications in research and drug discovery. This ALT activity assay is based on the quantification of pyruvate produced by ALT. In this assay, pyruvate and NADH are converted to lactate and NAD by the enzyme lactate dehydrogenase (LDH). The decrease in NADH absorbance at 340 nm is proportional to ALT activity.
