[Antigenic differentiation of blood stains by the Lewis system in practical forensic medical expert evaluation].
A modification of quantitative absorption and absorption elution tests with blood stain washing before the absorption phase is presented. Due to washing, the effect of carrier object on anti-Le(a) and anti-Le(b) sera is decreased and the sensitivity of the method is increased. Additional adsorption of the sera and elution into test erythrocytes treated with protease C is suggested for increasing the number of standard sera fit for the absorption-elution test. A new technology for preparing anti-Le(a) and anti-Le(b) immunoreagents is described.
