Abstract

Blood samples from unrelated Caucasian individuals from Antioquia (Colombia) were collected. DNA was extracted from 200 µL of peripherical blood by the salting-out procedure (1). The primer sequences of loci and cycling conditions were as recommended in previous studies (2–4) o from Genome Database (http://www.gdb.org). The PCR products were analyzed using denaturing 4% acrylamidebis-acrilamide gel electrophoresis and detected by silver staining. Alleles were identified based on the number of repeats and their attribution was made by comparison with an in-house constructed allelic ladder and following the published nomenclature (2–4) and ISFG guidelines for STR analysis (5).
