Our Protocols
I) Cloning
The construction of fusion genes involves the assembly of genes for passenger proteins and anchoring motifs. Both had to be fused while avoiding unnecessary cloning scars. We generated and provided all integration vectors for the transformation of B. subtilis. To keep an overview of the cloned constructs every plasmid was assigned to an ID: pIG16_000. All used oligos were assigned to an ID as well: oIG16_000. The complete list of the resulting bacterial strains and oligos can be found in the attached tables. The spore coat proteins cotZ, cotG, cotB and cgeA were amplified from the genome of B. subtilis 168. The anti-GFP nanobody and the GST were amplified from plasmids provided by Dr. Nicole Gensch and Dr. Maximilian Ulbrich. For the cloning strategy see Project - Approach.

II) Bacillus subtilis
Lab group 2 is responsible for all the basic work with our model organism Bacillus subtilis. We are looking after making Bacillus subtilis competent, the transformation of our constructs, the selection, cultivation and of course the sporulation aka the making of our nanocillus. We basically provide the groundwork so everyone else can keep on working.
III)Expression analysis
IV) Targeting
The mission of lab group 4 is to verify that our spores are able to bind on a target structure. We validate that the spores are exposing the nanobody on their surface by binding GFP. The GFP binding is verified by fluorescence microscopy and FACS anylysis.
V) Delivery
Focus of lab group 5 is the confirmation of the enzymatic activity of our spores. To show that the GST is correctly expressed by the spores we use a GST-assay adjusted to the use in a plate reader. Another application of our spores would be for a (anti-dandruff) shampoo, so we test this by washing a GFP-coated surface with different detergents and our construct and measuring the fluorescence.
