A method of acutely isolating rat dorsal root ganglion neurons for patch-clamp study of single-channel / 中国应用生理学杂志

<p><b>OBJECTIVE</b>To establish a method of acutely isolating dorsal root ganglion (DRG) neurons for patch clamp study of single-channel.</p><p><b>METHODS</b>DRG neurons of rats were acutely isolated by enzymatic digestion and mechanical blowing.</p><p><b>RESULTS</b>The acutely isolated DRG cells were easy to form the higher sealing resistance (> 5G Omega), which lowered noise level, so that pA-level single channel currents could be recorded.</p><p><b>CONCLUSION</b>The acutely isolated DRG neurons in this study are an ideal for patch-clamp study of single-channel.</p>
