Dear CCP4ers, We've been struggling with little (nearly none) expression of our protein, in both E coli and with in vitro transcription/translation methods. It appears that our mRNA has high 2' structure with a low dG (theoretically ~760kcal/mol). If this is indeed the source of our problem, are t

Is your gene of interest smaller than 750bp ? Then I would synthesize the gene with IDT and optimize it for E.coli that's 139$ Jürgen .. Jürgen Bosch Johns Hopkins Bloomberg School of Public Health Department of Biochemistry & Molecular Biology Johns Hopkins Malaria Research In
