Protein Refolding Service / Protein Production Service in E. coli.
From gene cloning/synthesis to purified proteins
Bacterial E. Coli. (Escherichia coli) Cells
Inclusion body production + protein refolding
Typically expressed as native protein without a tag. If necessary, small
tags such as 6X his and Flag can be used.
Purified recombinant proteins (quantities to be specified by customer)
typically >90% purity by SDS page

In E. coli. expression system, there are still many proteins that can only be expressed as inclusion body and have to be refolded into soluble and function forms. Protein refolding is an art work that needs lots of experience and hard work.
Sino Biological has devoted significant resources in development of protein expression and production in E. coli. system. We have developed in house a refolding buffer screening system that allows us to quickly identify suitable buffers for refolding for a particular protein. In the past couple of years (2008-2014), we have successfully produced over 1000 recombinant proteins using our E. coli. expression system. Many of these proteins are tough ones that cannot ...... < Learn More>
