Amplite® Colorimetric L-Alanine Assay Kit

Colorimetric detection: Uses Quest Fluor™ L-Alanine Sensor to detect hydrogen peroxide generated by an enzyme-coupled reaction.
Quantitative range: Measures L-alanine using standards from 1.563 to 100 µM.
Enzyme-coupled chemistry: Converts L-alanine into a proportional hydrogen peroxide signal.
Microplate compatible: Read absorbance at 575 nm using a clear-bottom microplate.
Applications: Suitable for L-alanine quantitation in biological and metabolic research samples.

Overview

L-alanine (L-Ala) plays a crucial role as a building block of important proteins. L-alanine is mostly synthesized by the muscle cells from lactic acid and absorbed into blood via the liver. It is converted into pyruvate by glutamic-pyruvic transaminase to enter the metabolic mainstream. L-Ala is critical for the production of glucose and hence blood sugar management, and plays an important role on the immune system and prevention of kidney stones. Insufficiency of L-alanine is usually a sign of poor nutrition, low protein diet, as well as stress. AAT Bioquest's Amplite® Colorimetric L-Alanine Assay Kit offers a sensitive colorimetric assay for quantifying L-alanine in biological samples. It utilizes an enzyme coupled reaction that releases hydrogen peroxide, which can be detected by Quest Fluor™ L-Alanine Sensor in an absorbance microplate reader at 575 nm.
