You may also send us an e-mail to our customer service department at info@chiscientific.com. 
 
Bacterial Expression (Cat No. 1-81501): This is the most common and economical solution to expressing a protein. Over the years, CHI Scientific has developed proprietary technologies to various proteins. With our Opti-Codon™ technology, our overall success rate in this category of orders is at >90% which is well above the industry standard. The one-stop service package starts from $1400.00, takes about 4 weeks and delivers 3 mg of highly purified proteins.
 
Yeast Expression (Cat No. 1-81502): Itis the most economical eukaryotic expression system for both secretive and intracellular proteins. It is ideally solution for large-scale production of recombinant eukaryotic proteins.It takes 5-6 weeks to deliver 3 mg of highly purified proteins, starting from $2000.00 per protein.
 
Insect Cell Expression (Cat No. 1-81503): The baculovirus expression system is suitable for production of high quality and functioning proteins. There are several well recognized advantages of insect cells over E. coli such as improved solubility, ability to incorporate post-translational modifications (protein folding), and higher yields for secreted proteins.  It takes 5-6 weeks to deliver 3 mg of highly purified proteins, starting from $2500.00 per protein.
                                               
Mammalian Cell Expression (Cat No. 1-81504): Mammalian cells have the ability to produce the most complete post-translational modifications and to secrete functioning proteins that are correctly folded and contain the most complete tertiary protein structure. Mammalian cells are widely used in the production of recombinant proteins, antibodies, virus, viral-subunit proteins, and gene-therapy vectors. Large-scale and fast mammalian transient system for protein expression is of great concerns to researchers conducting drug discovery projects. It takes 7-8 weeks to deliver 100 µg of highly purified proteins, starting from $3800.00 per protein.
