constitutive expression of CBDcex fused to INPNC with 6xHis tag

CBDcex fused to INPNC with 6xHis tag is one of a series of surface expressing fusion proteins that make up biodevice that aims to be therapeutic solution against norovirus infections. This protein in particular is a cellulose binding protein(CBDcex) fused to surface expression anchoring domain(INPNC), connected by a 6xHis tag to be easily identified by Western blotting.
