Protocol for the analysis of DNA methylation using bisulphite sequencing. Method allows precise analysis of methylation in a certain region by converting all nonmethylated cytosines into tymines, while methylated cytosines remain unchanged. This method requires small amount of genomic DNA and therefore seems to be very useful for the analysis of clinical samples, where the material amount is limited. - [Read Analysis of DNA Methylation using Bisulphite Sequencing Protocol]

This protocol describes transfection of plasmid DNA into primary hippocampal neurons using DNA/calcium-phosphate (CaPO4) coprecipitation. The precise pH of the transfection medium and the incubation time of cells with the coprecipitate are critical for reproducible and efficient transfection. Once these parameters are optimized for a given plasmid, the method is easily adapted for transfection of other established cell lines. - [Read Transfection of Hippocampal Neurons with Plasmid DNA Using Calcium Phosphate Coprecipitation]
Tubulin is polymerized into microtubules by incubating tubulin at 37°C with GTP. A nucleation seed is added when the purpose is to assay microtubule elongation. Tubulin can also be polymerized for the purposes of recycling the tubulin or labeling the microtubules with fluorescently labeled tubulin. Based on the protocol by Timothy Mitchison of Harvard University.
