Once the rate/slope of each lane is extracted from the linear range of the time point data, it is expressed as rate (mOD/min) per microgram of cell lysate added per well.
Representative background-subtracted kinetic measurements from serially diluted HeLa cell lysates and tissue homogenates HLH, MLH, RLH.
The assay was used to determine the MDH1 activity in a series of normal cell lysates and tissue homogenates loaded at 250 µg/mL.
MDH1 activity in serially titrated HeLa cell fractions (Cyto = Cytoplasmic, Mito = Mitochondrial and Nuc = Nuclear) demonstrates the assay’s specificity to MDH1.
