Although there are several methodologies, the HRM is stated as a promising alternative that meets these conditions. Therefore, the PCR-HRM was standardized and validated for genotyping the SNPs CAPN4751, CAPN316, CAST2959, CAST282, E2FB and E2JW of 50 animals from Bos taurus and Bos indicus breeds, using PCR-RFLP as gold standard test. There was an agreement among the results obtained by PCRHRM, compared to PCR-RFLP, and high sensitivity, specificity and appropriate negative and positive predictive values for PCRHRM. Similarly, repeatability and reproducibility were verified after obtaining homogeneity in the intra-run and inter-run results. Although the results show that the PCR-HRM is an efficient technique, and allows to obtain reliable results in a short time, these can be affected by the extraction method, quality and quantity of DNA, among other undetermined factors that can generate false positives and atypical dissociation profiles. Therefore, these variables must be controlled and the PCR should be monitored to identify unusual dissociation curves, caused by excess or deficiency in the amplification. 2016 artículo científico 0034-7485 https://www.redalyc.org/articulo.oa?id=193045926003 en http://www.redalyc.org/revista.oa?id=1930 Revista Cubana de Ciencia Agrícola application/pdf Instituto de Ciencia Animal Revista Cubana de Ciencia Agrícola (Cuba) Num.1 Vol.50 |
