Amplite® Colorimetric Alanine Aminotransferase Assay Kit

Blue Color

Amplite® Colorimetric Alanine Aminotransferase Assay Kit *Blue Color* is a colorimetric assay kit for measuring alanine aminotransferase (ALT) activity in biological samples using an enzyme-coupled microplate assay.

Colorimetric detection: Measures glutamate generated by ALT through an enzyme-coupled blue color reaction.
High sensitivity: Detects ALT concentrations as low as 10 mU/mL in a 100 µL reaction.
ALT-specific reaction: Monitors ALT-catalyzed conversion of alanine and α-ketoglutarate to pyruvate and glutamate.
Microplate compatible: Read at an absorbance ratio of A570 nm to A610 nm using a clear-bottom plate.
Applications: Suitable for ALT measurement in various biological samples.

ALT dose response was measured with Amplite Colorimetric Alanine Aminotransferase Assay Kit in a 96-well white, clear-bottom plate using a SpectraMax microplate reader (Molecular Devices).

Overview

Alanine aminotransferase (ALT), also called serum glutamate pyruvic transaminase (GPT), is a member of transferase family. It catalyzes the reversible transfer of an alpha-amino group between alanine and glutamate, and is an important enzyme in amino acid metabolism. ALT is found mainly in liver and small amount in heart, muscle, and kidneys. In healthy subjects, serum ALT levels are low. However, when cells are damaged, such as acute and chronic hepatitis, obstructive jaundice, carcinoma of liver, myocardial infarction, ALT may leak into the blood stream and the ALT levels are significantly elevated. Therefore, determination of serum ALT level has great clinical and diagnostic significance. Amplite® Colorimetric Alanine Aminotransferase Assay Kit provides a quick and sensitive method for the measurement of ALT in various biological samples. ALT catalyzes the reaction of alanine and α-ketoglutarate to pyruvate and glutamate. The product glutamate is measured by the generation of a blue color product through an enzyme coupled reaction cycle. The signal can be read by an absorbance microplate reader at an absorbance ratio of A570 nm to A610 nm. With the Amplite® Colorimetric Alanine Aminotransferase Assay Kit as little as 10 mU/mL ALT was detected in a 100 µL reaction volume. The assay is robust, and can be readily adapted for a wide variety of applications.
