Figure 6. Expression of Retrocyclins in Cervicovaginal Tissue Model Using Aminoglycosides.

Figure 6

(A) Cervicovaginal tissues were treated with PBS (Con) or 10 μl tobramycin (Tob) and incubated with rabbit preimmune serum or antiretrocyclin antibody. The slides were then incubated with biotinylated goat anti-rabbit IgG secondary antibody and then stained using FITC-avidin.

(B) Cytotoxicity was determined by measuring LDH activity in media underlying the tissues treated with PBS or tobramycin as indicated. Bars represent absorbance measured as 490 nm and error bars represent SEM; n = 6.

(C) HPLC trace of extracts of tissues treated with 10 μg/ml tobramycin (tissue + Tob) and 20 μg of synthetic RC-100.

(D) RC-100 synthetic peptide (indicated amounts), HPLC fractions 27–29 of control, tobramycin-treated, and RC-100 were dotted on a PVDF membrane and analyzed by immuno-dotblot.
