title: [The use of ultrathin isoelectric focusing in the study of traces of blood and secretions].
abstract: Four examples of the applicability of ultrathin layer isoelectric focusing in the investigation of bloodstains and stains of body secretions are given: -- differentiation of stains of human and animal blood; -- determination of fetal hemoglobin in bloodstains; -- subtyping of PGM1 isoenzymes in extracts of blood and semen stains; -- Gc typing of bloodstains using an immunofixation technique. For the visualisation of PGM1 subtypes a modified sandwich technique using a celluloseacetate membrane as separator between the focused gel and the visualisation agar is described.
