GVP Cluster

Discussion:

All colonies (transformants vector + promoter ligated with gvp) and o/n culture became red, so probably RFP is still in there... What might be the problem? The vector with promoter self-ligated due to uncomplete digestion (done 15 July 2009) leading to the following fragments:

• vector+RFP linear
• vector
• RFP

When the upper fragment (~2kb) is contaminated with linear vector this would lead high efficiency self-ligation instead of ligating gvp with the emtpy vector.

→TODO Therefore the restriction/purification/ligation will be redone and selection of non-red colonies will be made!

→DONE Also plasmid from the o/n cultures will be purified and analysed by restriction analysis.

• Used Sigma Plasmid isolation kit.
