Changes in electrophoresis pattern after interaction of supercoiled plasmid pBR322 DNA with avarol was studied at a micromolar concentration of reactants under mild reaction conditions. Interactions of avarol with linear high-molecular CT-DNA at millimolar concentrations were analyzed by electrophoresis and UV spectrophotometry. It was observed that avarol is capable of quenching ethidium bromide fluorescence in DNA bands. An increase in the absorbance of DNA was detected. The results indicate the binding of avarol to DNA and/or modification of nucleotide bases.
Proučavane su promene elektroforetskog ponašanja DNA posle interakcija superhelikoidalnog plazmida pBR322 s avarolom pri mikromolarnim koncentracijama reaktanata pod blagim reakcionim uslovima. Interakcije avarola sa linearnom visokomolekulskom CT-DNA pri milimolarnim koncentracijama analizirane su elektroforezom i UV spektrofotometrijom. Uočeno je da je avarol u stanju da gasi fluorescenciju etidijum-bromida u trakama koje potiču od DNA. Detektovan je porast apsorbancije DNA. Rezultati ukazuju na vezivanje avarona za DNA i/ili modifikaciju nukleotidnih baza.
