Promoter Library Sub-Project
Introduction
Up until now, this sub-project has seen the pGFP-rrnB plasmid backbone digested and linearised with restriction enzymes EcoRI and NheI. The resulting 8kb fragment (which is the plasmid backbone) has been successfully excised from agarose gel and purified; it is into this plasmid backbone in which we will place our sigA promoters.
Today's work involves the amplification of the promoter library (a collection of sigA promoters specified by degenerate sequences) using PCR.
Preparing the PCR
The first task carried out was the rehydration of the primers involved with this sub-project. A final concentration of 200uM is the desired value and to get this for each primer, the following calculation was observed:
Amount of water to be added (ul) = amount of primer (nMoles) x 5
The table below shows the oligos involved in this practical along with the primer amounts (in nMoles) and the amount of water needed (in ul) to make the primers at a concentration of 200uM
Oligo | Purpose | Amount (nMoles) | Water added (ul) |
