pH effect on BGAVs. A. FSE cells at PD 34 stained at pH 4.0. All cells demonstrated some degree of staining. B. BGAVs are inversely related to the pH at which the reaction was carried out. Staining was performed on FSE cells at PD 42 under different pH conditions. C. The effect of increasing PDs on BGAVs obtained at pH 4.0. FSE cells at progressively increasing PDs were stained at pH 4.0 and analyzed for BGAVs. D. The effect of H₂O₂ on BGAVs obtained at pH 4.0. FSE cells were treated with progressively increasing H₂O₂ concentrations and BGAVs were determined at each concentration.
