Molecular biology is the study of biology which deals with the molecular basis of biological activity. This branch of study tightly overlaps with other areas of biology and chemistry especially genetics and biochemistry.
Brendan Babb’s Collection of Protocols and Recipes
This is a comprehensive collection of bacterial, protein, and molecular biology techniques, recipes, and protocols. In addition to the large collection of bacterial methods, DNA and RNA protocols, protein and PCR techniques, this site hosts avery useful set of recipes for general and specific laboratory solutions and buffers. These are arranged in alphabetical order from acrylamide to zinc sulfate.
A HUGE list of laboratory protocols. Very useful.
DNA Purification Techniques, DNA Transformation/Library Preparation, Southern/Northern Blotting, DNA Sequencing, Oligonucleotides, PCR and Related Methods, RNA Methods, Protein Electrophoresis, Protein Purification, Autoradiography Tips,
Comprehensive Protocol Collection
This resource attempts to offer a comprehensive collection of molecular biology and Nematode-related protocols. The site links to protocols either maintained directly by the Ambros Lab or at other locations around the world.
Concentration of DNA by ethanol precipitation
Typically, 2.5 – 3 volumes of an ethanol/acetate solution is added to the DNA sample in a microcentrifuge tube, which is placed in an ice-water bath for at least 10 minutes. Frequently, this precipitation is performed by incubation at -20C overnight.

Detection of Nucleic Acids by Hybridisation
Nucleic acid hybridisation on membrane filters is a simple, sensitive, and specific means of detecting nucleic acid sequences of interest.
Preparation of genomic DNA from bacteria Modified from Experimental Techniques in Bacterial Genetics, Jones and Bartlet, 1990)
