General description

Tyrosine (Tyr) is an aromatic amino acid that is a precursor of several important substrates such as catecholamine, thyroid hormone, and melanin pigment. A deficiency in enzymes such as homogentisic acid oxidase or phenylalanine 4-hydroxylase that degrade tyrosine result in rare, hereditary metabolic disorders.


Suitable for the detection of tyrosine in a variety of biological samples.


The Tyrosine Colorimetric Assay Kit provides a simple assay for measuring tyrosine in biological samples (ranging from 5-75 nmole/well). Tyrosine is determined by measuring a colorimetric product with absorbance at 492 nm (A492) proportional to the amount of tyrosine present.
