Neuronal cell lines should be sufficiently simple to transfect. If you're using an already-established cell line, look for transfection reagents designed for it. Otherwise, use a reagent for neuronal cells (like N2a: https://altogen.com/product/neuro-2a-transfection-reagent-neuroblastoma-cells-ccl131/) and that should help you increase the overall efficiency.
It is true that a change in reagent can dramatically influence the becoming of your experiment ; and what was true for a version of a reagent may not be true for a new version of a reagent.
That is why I would like to present you a reliable and efficient alternative to classic transfection for primary neurones: NeuroMag
NeuroMag, a Magnetofection reagent (the use of a magnetic field to attract magnetized complexed of nanoparticles/nucleic acid) is a real good alternative.
Numerous paper demonstrated that NeuroMag was highly efficient for transfecting primary neurons with plasmid DNA (even long term cultured neurons) such as:
- hippocampal neurons: Charrier C. et al, Cell 2012 (http://www.ncbi.nlm.nih.gov/pubmed/22559944)
- cortical neurons: Courchet et al, Cell 2013 (http://www.ncbi.nlm.nih.gov/pubmed/23791179)
- or even motor neurons derived ES: Terenzio M et al, EMBO J 2014 (http://www.ncbi.nlm.nih.gov/pubmed/17475624)
Moreover, NeuroMag is also compatible with any nucleic acid (for gene silencing for example) such as:
- siRNA and miRNA in cortical neurons: Absalon S et al, J Neurosc 2013 (http://www.ncbi.nlm.nih.gov/pubmed/24027266)
Puesto que eres de Colombia es mejor escribirte directamente en español (disculpando al resto de lectores de este contenido). Resolviste tu problema con la lipo 3000? si es así me podrías comentar cómo...
I find Lipofectamine 3000 better and less toxic than Lipofectamine 2000. Higher efficiency and transfection rate. I use hippocampal neuronal cells. No problem with my experiments.
