AlphaLISA technology allows the detection of molecules of interest in buffer, cell culture media, serum and plasma in a highly sensitive, quantitative, reproducible and user-friendly mode. In an AlphaLISA assay, a Biotinylated Anti-Analyte Antibody binds to the Streptavidin-coated Alpha Donor beads, while another Anti-Analyte Antibody is conjugated to AlphaLISA Acceptor beads. In the presence of the analyte, the beads come into close proximity. The excitation of the Donor beads provokes the release of singlet oxygen molecules that triggers a cascade of energy transfer in the Acceptor beads, resulting in a sharp peak of light emission at 615 nm.

Aspartate transaminase (AST) or aspartate aminotransferase, also known as AspAT/ASAT/AAT or serum glutamic oxaloacetic transaminase (SGOT), is an important enzyme in amino acid metabolism. AST catalyzes the reversible transfer of an α-amino group between aspartate and glutamate. AST is found in metabolically active organgs and issues, such as the liver, heart, skeletal muscle, kidneys, brain, and red blood cells. Clinically, serum levels of AST and ALT (alanine transaminase) and their ratio (AST/ALT ratio) are used as biomarkers to monitor liver health. This kit has been designed for the detection of human AST in serum and cell culture media.

How it works

Principle of the AlphaLISA assay

The AlphaLISA assay is based on an AlphaLISA sandwich immunoassay involving a biotinylated anti-analyte antibody bound to Streptavidin-coated AlphaLISA Donor beads and an anti-analyte antibody conjugated to AlphaLISA Acceptor beads. Both antibodies are directed against the analyte of interest. In the presence of the target, both antibodies bind to analyte and the beads come into proximity. The excitation of the Donor beads provokes the release of singlet oxygen molecules that triggers a cascade of energy transfer within the Acceptor beads, resulting in emission with λmax at 615 nm. The intensity of the signal is directly proportional to the concentration of analyte present in the sample.

Protocol of the AlphaLISA assay

The AlphaLISA assay can be run in a 96- or 384-well detection plate (50 µL final). As described here, samples or standards are dispensed directly into the assay plate for the detection of the analyte of interest by AlphaLISA reagents. No washing steps are needed. The protocol can be further miniaturized or upscaled by simply resizing each addition volume proportionally.
