    Mammalian Transient Protein Expression Service

    The mammalian cell expression has the advantage of guiding the correct folding of protein, providing complex glycosylation modification. Therefore, the expressed recombinant protein is closest to natural higher biological protein molecules in molecular structure, physicochemical properties and biological function, and has better activity than prokaryotic expression system and eukaryotic expression system such as yeast and insect cell. HEK293 cells and CHO cells were used as expression hosts in the mammalian transient expression system of Clongene. With years of experience in protein expression, Clongene can provide flexible services to meet the needs of different customers.
