Bacterial Expression

Prokaryotic protein expression system is the most common and economical method of protein expression available today, and E.coli expression syetem is one of the important and widely used  prokaryotic protein expression system. Elabscience's E.coli Protein Expression System Service start with our proprietary codon optimization (S-CP-P001), followed by gene synthesis and sub cloning (S-CP-P002), protein expression and purification (S-CP-P003). Besides, we can produce your target protein in large scale (1~5L, S-CP-P004 or 1~30L, S-CP-P005). High-quality and purified protein can be delivered to you in as short as 3~5 weeks from project initiation. You can order every single service or any combination of these services according to your project program.

Submit your project information and requirements and place your order, our experienced experts will help with your research and promise you the high quality services with competitive price.


Competitive price: Starting from $1,200.

Short period: As short as 5 weeks.

Guaranteed Package: 2~10 mg of purified proteins with a competitive price of $1,980.

Flexible scale-up protein production: A wide variety of choices available (1L, 5L, 10L and 30L).

One-stop service platform: Elabscience® can take your project directly from gene synthesis to downstream activities including recombinant protein expression,antibody production, and assay development.
