Neae-intimin Construct Displaying anti-sfGFP Nanobody 7
Surface display of anti-sfGFP nanobody 7 using the bacterial protein Neae-intimin. The nanobody is a modification of GenBank ID: AIF28007. There is a linker between the Neae-intimin gene and the nanobody sequence. It has been optimised to express in pUS250 TOP10 E.coli.
Usage and Biology
Our project demonstrated that anti-sfGFP nanobody 7 binds to sfGFP through a GFP bindings assay. Therefore, nanobody 7 can be effectively surface displayed using Neae-intimin which provides preliminary evidence that other types of nanobodies can be displayed and later selected using the same construct.

Measurements at 400nm are taken to optimise for fuGFP fluorescence. This graph shows no significant binding to fuGFP when compared to the Neae negative control.

This graph shows significant binding to sfGFP for nanobodies H, 2, 3 and 7 when compared to Neae negative control. Nanobody 6 does not appear to bind sfGFP more than the negative control. Nanobody H appears to bind the most to sfGFP.
