Protein Expression and Purification

Starting from $1800,3-4 Weeks
We are a China leader in protein exprission and purification service.
We are a complete solution for your needs,and help you to overcome your cloning and expression bottleneck.We offer two of protein expression systems include bacteria and yeast from small to large scale with a full-range of purification options.Our services include:generating expression construct,establishing stable cell line,generating recombinant small-scale expression and purification,large scale expression and purification.

1. Fermentation service
    Culture growth of bacteria and yeast from 1-30 liter.
2. Generating expression construct
    Optimize and synthesize the gene that you desired.
    Subclone your gene into an expression vector.
3. Establishing high-expression stable cell line
    Yeast (pichia) high-expression cell line.
    BL-21 cell high-exprission cell line.
4. Small-scale expression and purification
    Optimization the expression condition.
