Contact dermatitis, 66(3), 123-127 (2012-02-11)
Skin-sensitizing chemicals that cause allergic contact dermatitis do so by reacting with self-proteins such that the modified structure becomes antigenic. The reaction chemistry involved is well characterized, but there are exceptions, such as the occasional allergen sodium metabisulfite. To identify
