This invention related generally to methods of detecting and quantifying biomarkers of oxidative stress in proteins. The biomarker may be any amino acid that has undergone oxidation (or other modification, e.g. chloro-tyrosine, dityrosine). Emphasis is given herein on oxidized sulfur- or selenium-containing amino acids (SSAA). The biomarker of oxidative stress in proteins may be detected with an antibody that binds to oxidized amino acids, specifically oxidized sulfur- or selenium-containing amino acids. The antibody may be monoclonal or polyclonal. The presence of biomarker or amount of biomarker present in a sample may be used to aid in assessing the efficacy of environmental, nutritional and therapeutic interventions, among other uses.

Biomarkers for oxidative stress

An apparatus and method for making a gradient gel. The present invention in one embodiment is a gel-making system that has a reservoir for holding a solution. The reservoir is connected to a movable arm through a tubing. The tubing has two ends: one end is in fluid communication with the reservoir; and the other, an open end, is received by the movable arm. A gel holder having an internal gel chamber is placed underneath the movable arm for receiving the solution. In operation, the movement of the movable arm causes the open end of the tubing to move along with it and the open end of the tubing delivers the solution in motion to the internal gel chamber to form the gel.
