Anybody aware if nanobodies against LPS and any other outer membrane protein for E.coli have been made? I wish to label the outer membrane quickly without having to genetically engineer fluorescent proteins on the outer membrane.
Depending on what you exactly want to do you may also simply use reactive dyes for labeling the outside of the cell / outer membrane, e.g. NHS-fluorescine or NHS-biotin plus labeled streptavidin.
