Determination of the HUMTH01 alleles by the APLP method.

We present a simple and rapid technique for determination of alleles at the HUMTH01 locus. The amplified product length polymorphism (APLP) method using two primers different in length, permits the differentiation between allele 9.3 and other alleles. The primers were designed to have an allele-specific nucleotide at the 3' terminal and 11 non-complementary nucleotides were added to the 5' terminal of one of the primers for the allele 9.3. The amplified fragment sizes for the alleles 9.3 and 10 were 80 bp and 70 bp, respectively. This method has proved to be very useful for forensic applications.
