Electrophoresis of human salivary proteins: Response to natural stimulation

Abstract
Human saliva was analyzed by sodium dodecyl sulfate‐polyacrylamide gel electrophoresis and the response to different natural stimuli investigated. Serva Blue R revealed pink/violet‐staining proteins (“lumicarmines”). These intensified following stimulation but in an unpredictable and sometimes disproportionate manner, causing pattern changes. This variable response undermines their potential forensic value for suspect identification.
