2-steps PCR
The 2-steps PCR is a technique used to add small DNA sequences to a PCR product. In the IGEM context, this can be used as an alternative to classical cloning: instead of digesting and ligating each biobricks, small part can be directly added by PCR, saving a lot of time.
The 2-step PCR requires three pairs of primer and three PCR runs:
A first pair is used to amplify a sequence of interest (for example an ORF) and provides annealing sites for the second pair of primers.
The second pairs anneals with the first and contains the sequence wanted to be add to the PCR product.
The third pairs of primer amplify the initial PCR product with the added sequence.
During our project, we used this technique to clone the ORF of the gene luxI with the prefix, a RBS, a terminator and a suffix. GELS?
