Protein Expression and Purification Services (E.coli expression system)


 

Recombinant Protein Production Service that is Dependable & Affordable

Gentaur's proprietary protein expression and purification platforms (from E.coli) can help you produce high quality functional recombinant proteins used in biomedical and pharmaceutical research. Given our extensive expertise in the in-house gene synthesis service, we can start recombinant protein production project from anywhere you wish (from your own plasmids or start from de novo gene synthesis)! 

Recombinant Protein Production Service Highlights

  • 10% off the first time orders.
  • As little as $1790 for 3mg protein, >85% by SDS-PAGE (see Package #PE1000 below).
  • Guarantee the protein quantity and purity - or it's free!
  • High success rate with fast turnaround time - as little as 4 weeks.

  • Customer to provide the plasmid or the expression strain. If there is no material to provide, Gentaur can start with de novo gene synthesis starting at $0.35/bp. The above package prices are quoted based on friendly or optimized target protein sequences. QC data includes SDS-PAGE & Western Blot (WB is available only for HIS or GST tagged proteins). For other tagged proteins, additional charges may apply for WB detection if required. Gentaur does not guarantee the endotoxin level of purified protein; Endotoxin removal can be requested at additional cost.
  • Gentaur guarantees protein to be soluble, but not the bioactivity or functionality. If target protein expresses as inclusion body, refolding will be done to make it soluble - unless otherwise specified in the order.

Quote Request for Recombinant Protein Production

 

Send us an email with this form filled:

1. Protein name and species.
2. Protein sequence or accession number.
3. Do you have plasmid or expression strain for expression? If not, we can start with gene synthesis - will you require codon optimization to improve expression level?
4. Please choose one of our standard e. coli protein expression packages, or specify the following:
a) Protein qty - 3mg/5mg/10mg/15mg/more:
b) Protein purity - 85%/95%: 
c) Tag removal - do you want us to remove Tag in purification steps at additional cost?
d) Refolding - if target protein expresses as inclusion body, refolding will be done to make it soluble. Please advise if you do not wish us to attempt refolding.
