Avidin prevents biotinylated proteins from binding to Strep-Tactin columns during Strep-tag protein purification. Biotin must be masked by the addition of Avidin prior to the application onto the column, since biotin is capable of binding to Strep-Tactin thus disturbing Strep-Tactin chromatography.
