Dissociated adult DRG neurons offer the possibility to study mature neurons that may better resemble the in vivo characteristics of these cells.However, adult DRG neurons culture is a complex, time-consuming process.In this study,DRGs were dissected and stripped in F12 and dissociated with collagenase, trypsin and DNAse prior to mechanical trituration.Compared with traditional method, this one reduced the experimental time from 3 hrs to 110 mins.
