Analysis of DRB3 gene polymorphisms in Jafarabadi, Mediterranean, and Murrah buffaloes from Brazil
“Analysis of DRB3 gene polymorphisms in Jafarabadi, Mediterranean, and Murrah buffaloes from Brazil”, vol. 15, p. -, 2016.,
The DRB3 gene is an MHC class II gene that has a high degree of polymorphism with more than 100 alleles described in cattle. This variation contributes to differences among individuals in immune responsiveness and disease resistance. In this study, we searched for allelic variants in exon 2 of the DRB3 gene in 80 river buffaloes of three breeds in Brazil using a PCR-RFLP technique. The PCR product showed genetic polymorphism when digested with RsaI, PstI or HaeIII restriction enzymes.
