Hyperpolymorphic short tandem repetitive DNA sequences, STRs or microsatellites, have become widely used in human identification, particularly in criminal cases and in mass disasters. In such cases the substrates for the analyses may be decomposed biological material, a fact that has to be taken into account when choosing the appropriate casework methods.(More)

We have studied the allelic diversity and de novo mutations at the hypervariable minisatellite locus D7S22. A four-state minisatellite variant repeat unit mapping by PCR (MVR-PCR) method was developed for this purpose, and a substitution polymorphism close to the repeat array was used to design allele-specific flanking primers to study individual haplotypes(More)
The C4 polymorphism in man has been studied by immunofixation electrophoresis, crossed immunoelectrophoresis, and functional detection after agarose gel electrophoresis. It has so far not been possible to reveal this polymorphism by isoelectric focusing and functional detection of C4 bands. Three common alleles and one less frequently occuring allele have(More)

The postmortem decrease in central brain temperature in a small number of forensic cases is presented. Each case shows a simple exponential fall during the time of the measurements. The data reported by Brinkmann et al. (1978), when plotted in semilogarithmic coordinate system, also show--after an initial "plateau" of about 2 h--a strictly one-term(More)
