Fluorimetric Quantitation of Lactate Dehydrogenase
L-LDH dose responses were measured with Amplite® Fluorimetric L-LDH Assay Kit in a 96-well black plate. As low as 1 mU/mL L-LDH in a 100 µL reaction volume can be detected with 30 minute incubation.
AAT Bioquest's Amplite® Lactate Dehydrogenase Assay Kits provide both fluorescence- and absorbance-based methods for detecting either L-lactate dehydrogenase (L-LDH) or D-lactate dehydrogenase (D-LDH). In the enzyme coupled assay, LDH is proportionally related to the concentration of NADH that is specifically monitored using a fluorogenic NADH sensor. The fluorescence signal can be read using a fluorescence microplate reader at Ex/Em = 540 nm/590 nm. We were able to detect as low as 1 mU/mL L-LDH in a 100 µL reaction volume. The assays are robust, and can be readily adapted for a wide variety of applications that require the measurement of L-LDH.
