Abstract
A total of 65 blood samples collected from Holstein cattle were employed for DNA extraction. Genomic DNA were amplified by means of random amplified polymorphic DNA (RAPD). One hundred and one random primers (Operon kits OPAA, OPAO, OPAV, OPC, OPE and OPA-06) were used for polymerase chain reactions (PCR). The PCR products were size fractionated by means of electrophoresis in agarose gel, transferred to a nylon membrane, and then hybridized with a alpha-32P-labeled microsatellite probe for random amplified microsatellite polymorphism (RAMPO) analysis. All the primers produced many amplification patterns in RAMPO fingerprints, but only OPE-01 (5'-CCCAAGGTCC-3') yielded a male-specific strong signal. Among the 65 cases, the specific band could be observed in the RAMPO fingerprints of the 24 male samples but not in the 41 female samples. Therefore, this specific band is peculiar to male cattle.
