Shuimu mainly employs three expression systems (bacteria, insect, and mammalian cells) to prepare quality target proteins, especially challenging ones such as membrane proteins and large protein complexes. We are also experienced in producing a comprehensive suite of recombinant proteins, such as enzymes, kinases, transcription factors, immunity-related proteins, and epigenetic proteins.
