The labels will place inside the tube, in contact with sample and the EtOH. The ethanol is 96 % or near absolute to preserve DNA. My question is if anyone knows if propylene material can detach chemicals (like acidification o similar) o can react with EtOH and cause damage to DNA. <o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US>Advices and experiences are welcome!<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=MsoNormal><span lang=ES-TRAD>Thanks in advance<o:p></o:p></span></p><p class=MsoNormal><span lang=ES-TRAD><o:p> </o:p></span></p><p class=MsoNormal><span lang=ES-TRAD>Sergio<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p><p class=p1><b>Sergio Montagud Alario</b><o:p></o:p></p><p class=p1>Museo [UV] Història Natural<o:p></o:p></p><p class=p1>Universitat de València<o:p></o:p></p><p class=p1>C/.
