    Notes: Abstract We amplified, via PCR, DNA segments from intron 1 of the tyrosine hydroxylase gene (TH01) and intron 40 of the von Willebrand factor gene (VWA) in ten nonhuman primate genera. In humans both introns contain polymorphic microsatellites with tetrameric repeats. Compared to the allelic ranges in human populations relatively short repeat arrays could be detected for the nonhuman primates typed, presumably reflecting an ancient precursor state at both microsatellite loci. Furthermore, our results provide evidence for an association of the average number of repeats present in different primate genera and their divergence time from man. DNA sequencing of VWA orthologues revealed a relatively high variability in the arrangement of repeats in the 5′-repeat arrays, the generation of which could probably be explained by polar mutational events.

    Description / Table of Contents: Zusammenfassung Zur Individualisierung menschlicher Urinproben - in Anlehnung an Dopingfälle im Sport - wurden VNTR-DNA-Polymorphismen untersucht. Der Nachweis erfolgte mit dem Single-locus-System YNH24/ Hinf I (RFLP-Technik) and den PCR-VNTR's Apo B und COL2A1 (AMPFLP's) Bowie SE 33 and TC 11 (STR's). 20 Urinproben (3 unterschiedliche Extraktionsvolumina: 10 ml - 1 ml - 0.1 ml) wurden nach (1) 2 Tagen Lagerung and (2) nach 2-5 wöchiger Lagerung bei 4°C typisiert. Die STR-Systeme führten bei 2 Tage alten Urinproben in allen Fällen zu positiven Ergebnissen (minimales Urinvolumen: 0.1 ml), die AMPFLP's in 4 von 8 (Apo B) bzw. 5 von 8 (COL2A1) Fällen; der Nachweis mit YNH24 gelang in 1 von 3 Fällen. Die mehrwöchig gelagerten Urinproben konnten weder mit YNH24 noch mit AMPFLP's typisiert werden. Mit STR's hingegen verliefen auch these Nachweisversuche positiv.
    Notes: Summary VNTR polymorphisms were investigated for the possible individualisation of human urine samples with reference to doping cases in sport. Investigations were carried out with the RFLP single locus system YNH24/Hinf I and the PCR-VNTR systems Apo B and COL2A1 (AMPFLLs) as well as SE 33 and TC 11 (STRs). Urine samples were tested using 3 different volumes (10 ml, 1 ml and 0.1 ml) after 2 days and 2-5 weeks storage at 4°C. Positive results were obtained for STR systems in all cases and with the smallest volume of urine tested (0.1 ml). The AMPFLP systems gave positive results in 4 out of 8 (Apo B) and 5 out of 8 (COL2A1) samples and YNH24 was successful in 1 out of 3 samples. Negative results were obtained for the AMPFLP systems and YNH24 after longer storage periods whereas the STRs were positive.
