Hello,

I have two recombinant proteins that are expressed as inclusion bodies and when I try to purify these inclusion bodies I obtain many contaminants. I have been using  a buffer composed by sodium phosphate 20 mM, NaCl 500mM and Imidazole 10 mM, followed by lisozyme (1mg/mL) and sonication, in bacterial lysis process. Then I use the same lysis buffer + Urea 8M to denaturate my protein. Does anybody know how can I obatin inclusion bodies with high purity?
Thanks very much!
