| Methionine Adenosyltransferase (MAT) activity assay kit Sample Type: Yeast and other expression system, tissue Applications: Levels of MAT1A/1B, MAT2A gene expressions. Extent of turning methionine into active methionine, i.e., SAM, related to methylation capability. Test Principle: This kit is designed to calculate MAT activity through measuring the concentration of the main product SAM. The chemical reaction and the competition cELISA are carried out simultaneously, so that the SAM synthesized from the chemical reaction competes with antigens coated on the microtiter plate for the horseradish peroxidase conjugated anti-SAM antibody the minute it is generated. The SAM quantified based on the amount of the HRP-anti-SAM antibodies that was made not to bind to the microtiter plate.
