J23104+B0032+INP+sfGFP

Ice nucleation protein(INP)is a secretory outer membrane protein from Pseudomomas syringae P. flurorescens and several other Gram—negative bacteria.In the bacterial surface display technology，INP is widely used as a functional carrier protein.

Design

We got the INP from BBa_K523013 constructed by iGEM11_Edinburgh. To test the surface display efficiency of INP, we added sfGFP to the downstream of INP, and expressed the fusion protein under the control of J23104 and B0032.

Microscopy result

We observed the fluorescence under the super-resolution microscope. As figure 1 shows, The intracellular expression of sfGFP displayed the rode-shape of E.coli, while the signal of surface displayed sfGFP showed the dotted pattern, which suggested that the sfGFP were gathered and distributed at the surface of E.coli..
