Human Anti-PEth Autologous IgG ELISA

Alcohol-Related Biomarker Detection

Anti-PEth autologous IgG ELISA workflow

Anti-PEth Autologous IgG ELISA
The quantity of Anti-PEth Autologous IgG in serum can be estimated by comparing the values from the wells containing the diluted samples with the values from the standard curve.
Figure 1 (top right): Plot the absorbance values obtained vs. amount of Anti-PEth IgG per standard to generate a standard curve.
Figure 2 (down right): Determine where the diluted sample values lie on the curve to obtain a measure of Anti-PEth IgG in your samples.

  • Human Anti-PEth Autologous IgG ELISA is a direct assay in which the signal is proportional to the amount of autologous anti-PEth IgG contained in the sample. The serum (or plasma) sample is added to a PEth-coated plate for binding. A peroxidase-linked secondary detector and colorimetric substrate are used to detect the amount of anti-PEth antibody bound to the plate. The colorimetric signal is read at absorbance 450 nm and is directly proportional to the amount of autologous anti-PEth IgG in the sample.
  • Ethanol (EtOH) has multiple effects on humans and other animals. Alcohol addiction and organ damage are active areas of research with a need for research reagents and tools. Phosphatidylethanol (PEth) is a direct metabolite of EtOH and has been described as a long-lived biomarker for alcohol ingestion. It is possible that PEth is involved in the neurological, protective, and harmful effects of alcohol, but the mechanisms are still being explored.
  • Autologous anti-PEth antibodies are found in lower abundance in serum from heavier drinkers. An inverse relationship between anti-PEth IgG levels and alcohol ingestion has demonstrated a high degree of correlation with ingested alcohol. Measuring these autologous anti-PEth IgG levels may serve as an effective biomarker in monitoring alcohol use.
