Protein expression in E.Coli
This protocol described a strategy of parallel expression of a protein from a variety of vectors containing different tags and/or fusion partners, and a variety of E. coli host strains.
The strategy to expression recombinant protein in e.coli involves two steps: 1. To Clone your gene of interests into a variety of e.coli expression vectors with different expression tags or fusion proteins and express them in a basic e.coli strain. 2. To clone your gene of interests into a regular e.coli expression vector and express it in a variety of e.coli hosting strains.

I have ever met this problem. I try to express NPM-ALK protein in Ecoli. I checked the construct is correct. and I tried different expression condition. Stil I did not get so much protein. Hope to get some help from you. thanks.

very helpful, thank you for putting this together; i'm trying to express a large GST-fusion protein and have protein expr at baseline and multiple, shorter protein products with induction. the various suggestions will hopefully work. thank you.

hi.
I construct GST fustion protein
but, protein expression so bad
i try any conditin by Troubleshooting protocol
my insert is 2.3kbp
will it be a big trouble?
