On demandThermo Scientific™ Zeba™ Dye and Biotin Removal Spin Columns, 0.5 mL, 2 x 25 Columns
The Thermo Scientific Zeba Dye and Biotin Removal columns enable fast and efficient removal of non-reacted fluorescent dyes, biotin, reducing agents, and crosslinkers from protein samples. Removing free-dye after a labeling reaction is often difficult and time-consuming but is essential for accurate determination of dye-to-protein ratios. The Zeba Dye and Biotin Removal resin is highly specialized to produce exceptional protein recoveries while effectively removing non-conjugated fluorescent dyes, biotinylation reagents, reducing agents, and crosslinkers. Using the appropriate amount of sample and buffer conditions, almost any fluorescent dye can be removed with these columns. Even dilute protein samples (25 µg/mL) can be successfully processed to remove dyes, biotin, reducing agents, and crosslinkers and to efficiently recover proteins (>7 kDa). A single 0.5-mL Dye and Biotin Removal Spin Column can process a 50 to 120 µL of sample. This product is not recommended for desalting or buffer exchange.
