Aladdin™ Dye Removal Columns

Product introduction： Dye Removal Columns effectively bind to unconjugated fluorescent dye molecules from protein solutions to rapidly purify fluorescent conjugated antibodies and other proteins after labeling reactions. These Fluorescent Dye Removal Columns enable fast and efficient removal of non-reacted fluorescent dyes from protein labeling reactions. 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. Features of Dye Removal Columns: • Fast —removes free, unconjugated dye from labeled protein solutions in less than a minute • Specific —purification resin provides outstanding conjugate recovery (75 to 95%) • Customizable —separate resin and microcentrifuge columns allow optimization for different dyes and concentrations of sample • Sample-friendly —processing results in minimal sample dilution This product has been used successfully to remove excess, unconjugatedfluorescein,rhodamine and DyLight Dyes from antibodies following labeling reactions. Samples with dyes in the green spectrum, such as Dylight 549 and rhodamine, might require double processing because they require a high molar excesses for labeling. When using fluorescent dyes other than those described in the product instructions, the ratio of resin to protein/dye mixture will require optimization.
