Inclusion Bodies - Wikipedia
70-80% of recombinant proteins expressed E. coli are contained in inclusion bodies (i.e., protein aggregates). The purification of the expressed proteins from inclusion bodies usually require two main steps: extraction of inclusion bodies from the bacteria followed by the solubilisation of the purified inclusion bodies. Pseudo-inclusions ... Read Article

Affinity purification Of GST Fusion Proteins - Yale University
Subsequent purification is to fuse a protein with a glutathione-S-transferase (GST) domain. The DNA encoding for this 25 kDa protein domain is ligated in-frame with the gene for the desired protein so that, upon expression, your desired protein is fused to the GST domain. This is an incredible help in protein purification, since GST ... Fetch Document
