Description

• Developed specifically for the safe and simple removal of ethidium bromide (EtBr) from aqueous staining solutions and running buffers used in nucleic acid separation gels Concentrations in these solutions are 0.5 - 10mg/L EtBr is bound and concentrated by the adsorber column, allowing removal of the filtrate Each column normally binds at least 300mg of ethidium bromide from TAE or TBE buffers Residual capacity is easily visualized because the EtBr appears as a dark red to black band on the column As long as this band has not reached the bottom of the column bed, the concentration of dye is still below the column capacity
