The pH stability is limited to low strengths and short times at extremes of pH 2-10, particularly in the acid range.After any washes using solutions at extremes of acidic or basic pH, the Sephadex®should be washed and reequilibrated with buffer at neutral pH as promptly as possible.
How can I clean the Sephadex®G-50, Product G5080,after use?
To clean the gel, you can wash the gel with 2 column volumes (CV) of 0.2 M NaOH, outside of the column because the gel will swell in basic pH, or in a solution of non-ionic detergent.Then you can rinse with water and re-equilibrate with 2-3 CV of buffer. If the resin is to be stored (longer than ~24 hours), equilibrate the resin with buffer containing an antimicrobial such as 20% ethanol or 0.02% sodium azide.
