Mammalian Protein Expression Service

Mammalian cell protein expression system possesses the perfect function of post-translational modifications, which promotes proper folding of the protein. BIC provides complete mammalian protein production services, including codon optimization, gene synthesis, DNA max-prep, protein expression and purification. According to your requirements, you can choose either transient transfection or stable cell line establishment for protein and antibody expression. The transiently transfected cell can express protein easily and rapidly, while stable cell line attains high yield and reproducible production of protein. Our dedicated staffs are looking forward to assisting you with any questions at any time.
