Design Notes

After constructing the plasmid, we transferred it into EcN for expression for subsequent operations, so that it can have a better expression level under the premise of ensuring the operation standard, so as to improve the binding rate and stability of the above membrane surface display system.


Experimental result

We transferred pET23a-CL7-sfGFP into Escherichia coli BL21 and purified it to meet the use requirements. The results were as follows:

It can be seen that the purified protein concentration and purity are high, and subsequent incubation binding and fluorescence confocal experiments can be conducted to verify the binding of Inak-Im7 and CL7-sfGFP (see the engineer and result section of wiki for the results).

Source

Inak is an ice nucleated protein from Pseudomonas syringae KCTC1832. linker is composed of Gly and Ser. Im7 is an immune protein derived from E. coli. The source of the composite parts is artificially constructed plasmids containing Inak and Im7 genes (pCold-Inak-Im7).
