RT Journal Article T1 Comparison of extraction methods for the recovery, amplification and species-specific analysis of DNA from bone and bone meals A1 Prado Rodríguez, Marta A1 Franco Abuín, Carlos Manuel A1 Fente Sampayo, Cristina Asunción A1 Cepeda Sáez, Alberto A1 Vázquez Belda, Beatriz Isabel A1 Barros Velázquez, Jorge K1 Bone meals K1 DNA recovery K1 Extraction methods K1 Polymerase chain reaction AB We report the effect of several parameters on the efficiency of recovery of DNA from animal bones. The effects of preheating the samples (at either 60°C or 100°C) at different intervals (from 1 h to overnight) in different media (water, 0.5 M ethylenediaminetetraacetic acid (EDTA), or 0.5 M EDTA + 0.05% sodium dodecyl sulfate (SDS) were investigated. The effect of slight (5 min) or intense (30 min) pretreatments with ultrasound was also evaluated. Several different treatments with proteinase K (ranging from 200 to 800 νg, and lasting from 1 to 3 h) at 65°C were also considered. Additionally, two different DNA extraction methods (based on silica resins and purification columns, respectively) were evaluated. The recovery of DNA from the samples was 40% higher when the bones were preheated in 0.5 M EDTA at 60°C for 1 h, this being followed by treatment with 800 νg of proteinase K for 3 h. The DNA thus obtained was successfully amplified by polymerase chain reaction (PCR) using a set of primers specific to a 359 bp region of the mitochondrial cytochrome b gene, and the species of origin were identified by visualizing the restriction fragment length polymorphism (RFLP) with the endonucleases PalI and MboI PB Wiley YR 2002 FD 2002-04-23 LK https://hdl.handle.net/10347/45602 UL https://hdl.handle.net/10347/45602 LA eng NO Prado, M., Franco, C.M., Fente, C.A., Cepeda, A., Vázquez, B.I. and Barros-Velázquez, J.
