Pierce™ Dye Removal Columns enable fast and efficient removal of non-reacted fluorescent dyes from protein labeling reactions.

• Removes free, unconjugated dye from labeled protein solutions in less than a minute
• Purification resin provides outstanding conjugate recovery
• Separate resin and microcentrifuge columns allow optimization for different dyes and concentrations of sample

Removing excess dye after a labeling reaction is often difficult and time-consuming but is essential for accurate determination of dye-to-protein ratios. The dye removal resin in this kit is highly specialized to produce exceptional protein recoveries while effectively removing non-conjugated dye. Using the appropriate amount of resin and buffer conditions, almost any fluorescent dye can be removed with this kit.
