What is polymerase chain reaction? If you have ever worked in a molecular biology laboratory you have likely done a polymerase chain reaction (PCR). PCR is an in vitro method in which a small amount of DNA can be copied many many times in a short time period. PCR was invented in ...
This post was contributed by guest blogger, Kristian Laursen from Cornell University. Site directed mutagenesis is a highly versatile technique that can be used to introduce specific nucleotide substitutions (or deletions) in a tailored manner. The approach can be used in ...
Molecular cloning requires some method of screening colonies for the presence of an insert. Traditionally this has been done with restriction enzyme digest; however colony PCR can accomplish the same thing in less time and for less money. The key steps to colony PCR are: 1) ...
In its simplest form, PCR based cloning is about making a copy of a piece of DNA and at the same time adding restriction sites to the ends of that piece of DNA so that it can be easily cloned into a plasmid of interest. You can use similar processes to add overhangs to your ...
