Easy-to-Use PureBlu Nuclear Staining Dyes

Bio-Rad Laboratories, Inc. 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.
