Protein production

Protein production - Mammalian Expression System

Mammalian expression service is recommended for cases in which the folding and post-translational modifications are crucial to the customer's intended application and cases in which the internal machineries of E.coli and baculovirus-insect cells are unable to express the protein in sufficient quality.

Protein production - E.coli expression system
Protein expression in E. coli system is divided into  Subcloning of cDNA of interest into an expression vector  and large scale recombinant protein production and purification.

Protein production - baculovirus expression system

The baculovirus-insect cell expression system is widely used to produce recombinant proteins for many different biomedical applications. It provides researchers with the means to generate milligram quantities of recombinant proteins that are ideal for functional and structural analysis.
