Protocoll to create a fixed suspension of sponge associated prokaryotes (SAP) from sponge tissue.This can serve as the basis for Fluorescence in situ hybridisation and/or cell sorting.This protocol was tested for different sponge species but might also be adapted to other organisms (let others know)The protocol was modified from :Fieseler L, Horn M, Wagner M, Hentschel U. (2006) Discovery of the novel candidate phylum "Potibactetia" in marine sponges (vol 70, pg 3724, 2004).
