sGFP11 is an engineered version of the final strand of the GFP beta-barrel.


sGFP11 is the smaller fragment of the Split-GFP system, encompassing the final β-strand domain of green fluorescent protein (GFP).The isolated GFP11 fragment does not fluoresce on its own and is typically fused to the C-terminus of the target protein. Upon binding with the GFP1-10 fragment(BBa_K5301012), it facilitates the restoration of GFP's fluorescent activity.


Usage and Biology

In our team's experiments, sGFP1-10 and sGFP11 are individually fused and expressed with the target proteins.We use the self-assembly of GFP1-10 and GFP11 to construct membrane protein dimers.


Characterization

We performed an in vitro mixing and incubation of sGFP1-10 with sGFP11 to achieve their binding(in the form of sGFP1-10 tether BBa_K5301017and sGFP11 tether BBa_K5301018). The images captured under a fluorescence microscope are shown in the figure below.

By comparing these results, the corresponding fluorescence signals are obtained to eliminate false positives.
