Amplite® Colorimetric L-Aspartate (Aspartic Acid) Assay Kit

Aspartate (or Aspartic acid) is a negatively charged, polar amino acid. Aspartate is involved in the control point of pyrimidine biosynthesis, in transamination reactions, interconversions with asparagine, in the metabolic pathway leading to AMP, in the urea cycle, and is a precursor to homoserine, threonine, isoleucine, and methionine. It is also involved in the malate aspartate shuttle. Amplite® Colorimetric Aspartate Assay Kit offers a sensitive colorimetric assay for quantifying aspartate in biological samples. Aspartate is converted to pyruvate that generates hydrogen peroxide through an enzyme coupled reaction. The amount of hydrogen peroxide generated by aspartate is monitored with Amplite® Red substrate for quantifying aspartate by in an absorbance microplate reader at 575 nm.

Aspartate dose response was measured with Amplite® Colorimetric Aspartate Assay Kit on a white clear bottom 96-well plate using a SpectraMax microplate reader with Path check ON (Molecular Devices).
