Figure Lengend Snippet: Effects of sex hormones on in vitro ClpB production. Changes of ClpB levels vs. control (CT) after acute application of several doses of testosterone ( A ) or estradiol ( B ) on E. coli cultures. ( C ) Immunocytochemical detection (green fluorescence) of ClpB in E. coli cultures treated with 4 doses of estradiol and in non-treated control (CT) bacteria as well as in ClpB-negative (Delta-) and -positive (Delta +) E. coli mutant strains, DAPI counterstaining. Magnification x 100 ( D ) Percentage of changes of ClpB-positive vs. total bacteria after estradiol treatment as compared to non-treated control (CT) bacteria and ( E ) their correlations with ClpB concentrations in culture medium. Effects of chronic application of estradiol on E. coli cultures on ClpB concentrations in bacteria ( F ) and culture medium ( G ) as well as on the ClpB secretion rate ( H ) and ClpB mRNA levels ( I ).

Article Snippet: For this purpose, 3 antibodies were used: Rabbit polyclonal anti- E. coli ClpB antibodies (Delphi Genetics, Gosselies, Belgium) as a capture antibody, mouse monoclonal anti- E. coli ClpB antibodies as a detection antibody (Delphi Genetics), and an alkaline phosphatase-conjugated goat anti-mouse revelation antibody (Jackson ImmunoResearch, Cambridgeshire, UK).
