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.

Characterization

RT-PCR

Fig.1: RT-PCR
1. marker, 2. INP-His-CBDcex (negative control), 3. INP-His-CBDcex

We designed PCR primers so that we would obtain PCR product with the length of 300 bp after RT-PCR. For negative control, reverse transcription was not performed.

Western blotting
