Cell Biolabs’ Lipoic Acid ELISA Kit is a competitive enzyme immunoassay developed for the detection and quantitation of total bound lipoic acid in biological samples. This assay is not recommended for detection of free lipoic acid at very high concentrations in samples. The kit has a detection sensitivity limit of 4 nM bound lipoic acid. Each kit provides sufficient reagents to perform up to 96 assays including standard curve and unknown samples.
