    Description / Table of Contents: Zusammenfassung Seren und Blutextrakte wurden auf Polyacrylamidgelen isoelektrisch fokussiert. Die fokussierten Proteine wurden auf Nitrozellulosemembranen durch Diffusion oder elektrophoretisch transferiert. Durch ein spezifisches Antiserum erfolgte auf den Membranen die AG-AK-Reaktion. Nach Waschen der Membranen wurde der gebundene Antikörper mit einem enzymisch markierten Anti-Kaninchen IgG-Antikörper nachgewiesen. Mit dieser Technik konnten die gruppenspezifische Komponente, das α2HS-Glykoprotein, die Komplementkomponenten C6 und C7, der Gerinnungsfaktor 13B und das Plasminogen sehr empfindlich phänotypisiert werden. Vorzugsweise konnten bis zu 6 Monate alte Blutspuren richtig typisiert werden.
    Notes: Summary Sera and bloodstain extracts were subjected to isoelectric focusing in polyacrylamide gels. The focused proteins were transferred to nitrocellulose membranes by diffusion or electrophoretically, then allowed to react with specific antiserum and, after washing, with peroxidase-labeled anti-rabbit IgG. The immune complexes formed on the membranes were detected with 4-chloro-1-naphthol and hydrogen peroxide. Serum group-specific component, α2HS-glycoprotein, the sixth and the seventh component of complement, factor 13B, and plasminogen could be phenotyped with high sensitivity. Bloodstains as old as 6 months could be correctly typed for α2HS-glycoprotein by the blotting technique.

    Notes: Abstract Binding isotherms of two types of ionic surfactants, CmH2m +1SO4Na (m = 8,10,12) and CnH2n + 1N+(CH3)3C1 (n=10, 12), to human hair in aqueous solutions were examined to clarify effects of hydrophobic and electrostatic interaction of ionic surfactants with hair. The binding isotherms of anionic surfactants showed cooperativity with discontinuously increasing shapes, while the binding isotherms of cationic surfactants showed a Langmuir-type, regardless of the difference of a hair condition. The calculated free energy change (— ΔG@#@) for binding, obtained from Klotz' plots, suggests that the binding processes are governed mainly by a hydrophobic interaction, and bound surfactants probably expose their alkyl chains to the aqueous phase, since no-ΔG was observed with the increase of m or n and values of enthalpy change(ΔH) were positive or zero.
