RNA can be extracted from blood since whole blood contains nucleated white cells that constitute an easily accessible source. RNA extraction from blood will be more successful if the nucleated white cells are first isolated from the red cells since the red cells are a rich source of ribonucleases that are able to degrade RNA. …

In the previous post, it had already explained about how to extract plasmid DNA by using alkaline lysis method. In this particular post, it will be explained the other method to extract plasmid DNA instead of using alkaline lysis method. It is Rapid Boiling method, an alternative to alkaline lysis method that was developed by …

Plasmids can be isolated by a variety of methods many of which rely on the differential denaturation and reannealing of plasmid DNA compared to chromosomal DNA. One commonly used technique developed by Birnboim and Doly involves alkaline lysis. This method essentially relies on bacterial lysis by sodium hydroxide and sodium dodecyl sulfate (SDS), followed by …
