I have been reading about cell-free protein expression systems. However my colleagues say they do not find many using the commercial PURE system which used recombinant expression elements. Does anyone know why? Is it flawed?
I would like to publish one huge table as Supplementary resources to a forthcoming paper. The R package 'plotly' enables the creation of interactive tables which can be searched, filtered for...

I had a crystal hit in a well with 0.1M HEPEs pH 7.5, 10%(w/v) PEG 4000, and 20%(w/v) isopropanol. Why is isopropanol in w/v here if it's just solvent? How do I recreate this well condition?
