Bio-Rad Launches Easy-to-Use PureBlu™ Nuclear Staining Dyes

Bio-Rad Laboratories, has announced the launch of its PureBlu™ Nuclear Staining Dyes, high purity formulations that simplify nuclear staining for fluorescence imaging experiments.

In cell imaging experiments, DNA binding dyes are used to locate a cell’s nucleus. Current offerings of the most commonly used dyes, DAPI and Hoechst 33342, usually require time-consuming weighing and/or multiple tedious dilution steps.

Bio-Rad’s PureBlu Nuclear Staining Dyes are high purity, pre-aliquoted formulations of such traditional chemistries for cell imaging experiments. These dyes eliminate the need for weighing and require only a single dilution step upon resuspension. PureBlu DAPI is the ideal option for fixed samples, while Bio-Rad’s PureBlu Hoechst 33342 is recommended for live cell samples, as it has greater cell permeability and reduced toxicity compared to DAPI.

Additional benefits of the PureBlu Nuclear Staining Dyes include:
• High quality results — high purity formulation (>95%) suitable for challenging experiments
• Ease of use — 5-vial pre-aliquoted format ensures that only the amount required is reconstituted to avoid wasting reagents
• Flexibility — can be easily combined with other stains and dyes for multicolor imaging experiments

PureBlu Nuclear Staining Dyes are compatible with the ZOE™ Fluorescent Cell Imager and other imaging systems with UV excitation sources.
