Biological CRO Services --->E.coli Expression

E.coli Expression  

E.coli has been used as a host to make recombinant proteins for many yeas, and have many advantages over other hosts in terms of the speed, cost, and productivity of obtaining end products. E.coli expression is the first choice for researches and biotechnology companies throughout the world to produce proteins.

ACRObiosystems produces proteins that do not require glycosylation using a proprietary expression vector and fermentation medium. Along with ACROBiosystem’s proprietary codon optimization tools, expression expertise, and powerful purification platform, we can guarantee greater than 5 mg of your purified protein for less than $1500.
