I just expressed my RPS2 yeast protein in E. coli, although it was not well expressed, but it was adequate. What else can I do with my expression construct?
pGEX plasmid serie is dedicated to GST fusion expression in bacteria. Apart from cloning with the view of expression in bacteria, there is nothing else to do with it! I guess the goal is to express protein for purification so try to improve culture condition in order to increase the yield of expression.
Now that you have expressed your first protein, you can make any protein in the whole wide world :) Maybe a piece of a virus coat, to produce a vaccine? Something pretty and fluorescent? Something from your own body? Only your imagination is the limit!
