Product Description

CF® dye-dUTP can be used for TUNEL assay, microarray, or to synthesize labeled DNA probes for in situ hybridization and nucleic acid blotting applications.

  • Synthesize exceptionally bright and photostable fluorescent DNA probes
  • Detect by fluorescence microscopy, flow cytometry, or in gel
  • Compatible with fixed cells or tissue sections
  • Choice of 8 CF® dye colors from blue to near infrared
  • Biotium’s CF® dyes have superior brightness, photostability, and are water-soluble

Supplied in lyophilized form. For PCR applications, Taq polymerase should be used with dUTP conjugates, because dUTP inhibits archaeal polymerases such as Pfu and Vent®. Also see our CF® Dye dCTP Conjugates and TUNEL assay kits, available with a wide selection of bright and photostable CF® dyes.

Superior CF® Dyes

Biotium’s next-generation CF® dyes were designed to be highly water-soluble with advantages in brightness and photostability compared to Alexa Fluor®, DyLight®, and other fluorescent dyes. Learn more about CF® Dyes.

1. CF®405S-dUTP may not be suitable for TUNEL staining in tissues due to blue autofluorescence in tissues and lower incorporation efficiency in tissue sections compared to other CF®dye dUTP conjugates. 2. CF®680R-dUTP has been tested in TUNEL staining of cells, but may not be efficiently incorporated in tissue sections.
