Abstract
The development of gene transfection technologies has greatly advanced our understanding of life sciences. While use of viral vectors has clear efficacy, it requires specific expertise and biological containment conditions. Electroporation has become an effective and commonly used method for introducing DNA into neurons and in intact brain tissue. The present study describes the use of the Neon® electroporation system to transfect genes into dorsal root ganglia neurons isolated from embryonic mouse Day 13.5–16. This cell type has been particularly recalcitrant and refractory to physical or chemical methods for introduction of DNA. By optimizing the culture condition and parameters including voltage and duration for this specific electroporation system, high efficiency (60–80%) and low toxicity (>60% survival) were achieved with robust differentiation in response to Nerve growth factor (NGF). Moreover, 3–50 times fewer cells are needed (6 × 104) compared with other traditional electroporation methods. This approach underlines the efficacy of this type of electroporation, particularly when only limited amount of cells can be obtained, and is expected to greatly facilitate the study of gene function in dorsal root ganglia neuron cultures.

Abstract
We investigated the efficiency of transfecting primary cultured rat postnatal brain neurons (substantia nigra pars compacta neurons and locus coeruleus neurons) with cDNA encoding GFP (jellyfish green fluorescent protein) using a calcium phosphate method. The proportion of transfected neurons (transfection efficiency) was approximately 5%, when cultures from the substantia nigra pars compacta were transfected 3 days after plating. The transfection efficiency decreased when cultures were transfected 10 days after plating (1.7%). Neurons were cotransfected at a very high probability ( > 78%) with the muscarinic m2-receptor cDNAs together with GFP plasmids. Transfected neurons were very healthy as indicated by the zero-current potential and the microscopical appearance. Because the transfection efficiency is low, this method cannot be used for experiments involving the whole cell population. The transfection efficiency of 1.7% corresponded to approximately 20 transfected cells per dish in our culture conditions and these cells are sufficient in number for electrophysiological studies. Therefore, this is an excellent method for studying the influence of exogenous genes on single neurons using electrophysiological techniques.
