DESCRIPTION

General description

Alanine is a nonessential amino acid that plays a key role in the glucose-alanine cycle between muscle tissue and the liver.[1] In amino acid-degrading tissues such as muscle, amino groups are pooled as glutamate by transamination reactions. The amino group of glutamate is transferred to pyruvate via alanine aminotransferase, forming alanine and α-ketoglutarate. The alanine is passed into the blood and transported to the liver.[2] This reaction is reversed in the liver where pyruvate can be used in gluconeogenesis to form glucose,[3] which may return to other tissues through the circulatory system. Increased alanine levels correlate with higher blood pressure, energy intake, cholesterol levels, and body mass index.

Application

Alanine Assay Kit has been used to determine the intracellular alanine pool.[4]

Suitability

Suitable for alanine detection in cell and tissue culture supernatants, urine, plasma, serum, and other biological samples.

Principle

In this kit, alanine concentration is determined by a coupled enzyme assay, which results in a colorimetric (570 nm)/fluorometric (λex = 535/λem = 587 nm) product, proportional to the alanine present. Typical detection ranges for this kit are 2-10 nmole (colorimetric) and 0.2-1 nmole (fluorometric).
