Abstract
The influence of various amplification parameters on the demonstration of COL2A1 patterns was examined in serial experiments. The combination of 6 optimized parameters (concentration of primers, nucleotides, Taq polymerise, K+, Mg2+, number of cycles) led to an approximately tenfold increase in sensitivity and a decrease in allelic drop-out. In unequal mixtures of DNA from 2 individuals the weakest component was detectable in dilutions down to 1:20. In a small population sample (n = 120) 10 alleles could be demonstrated. In Reihenversuchen wurde der Einfluß verschiedener Amplifikations-Parameter auf den Nachweis von COL2A1-Mustern untersucht. Die Kombination von 6 optimierten Parametern (Konzentrationen der Primer, der Nukleotide, der Taq-Polymerase, von K+, Mg2+, Zahl der Zyklen) führte zu einem ungefähr zehnfachen Anstieg der Empfindlichkeit. Der Allelverlust schien besser vermeidbar. In ungleichen Mischungen von DNA von zwei Personen konnte die schwache Komponente noch in Verdünnungen bis 1:20 nachgewiesen werden. In einer kleinen populationsgenetischen Studie (n = 120) konnten 10 Allele nachgewiesen werden.Keywords
