  • Simultaneous staining of both the nucleolus and the nucleus in live cells
  • High resistance to photobleaching and concentration quenching, ensuring strong, consistent fluorescence signal, even after extended viewing periods
  • Validated for utility in live cell imaging applications, demonstrating appropriate response to treatment with well characterized nucleolus-perturbation agents
  • Stringently manufactured, to control and eliminate non-specific assay artifacts
Enzo Life Sciences’ TOTAL-NUCLEAR-ID® Green/Red Nucleolar/Nuclear Detection Kit contains two proprietary dyes suitable for simultaneous live-cell staining of nucleoli and nuclei. The dyes allow examination of nucleolar dynamic changes in intracellular distribution, trafficking and localization arising from biological processes such as the cell cycle and ribosome biogenesis. The kit is compatible with most fluorescence detection systems, including conventional and confocal fluorescence microscopes, as well as High Content Screening (HCS) platforms. This kit is specifically designed for visualizing nucleoli and nuclei in living cells. A control nucleolus perturbation agent, actinomycin D, is provided for monitoring changes in nucleolar dynamics. Potential applications for this kit include monitoring impaired ribosome biogenesis, inhibition transcription, cell cycle dynamics and cellular stress, as well as the distribution, trafficking and dynamics of nucleolar proteins, the distribution of viral proteins, and potentially as an aid in identifying cancer cells.

Cells stained with NUCLEOLAR-ID® Green Detection Reagent show maximal fluorescence signal within the nucleoli, and faint fluorescence throughout the nucleus and cytoplasm (A). When the cells are treated with low doses of actinomycin D, loss of nucleolar staining is observed (B). Counterstaining with NUCLEAR-ID® Red Detection Reagent facilitates highlighting the nucleoli relative to the weak cytoplasmic staining.

ENZ-51006 IF
Live U2OS cells, stained with TOTAL-NUCLEAR-ID® Green/Red Nucleolar/ Nuclear Detection Kit demonstrates staining of the nucleus (red) and nucleolus (yellow-green) via fluorescence microscopy. As an RNA stain, NUCLEOLAR-ID® Green dye does display some cytoplasmic staining as well, but NUCLEAR-ID® Red dye facilitates unambiguous identification of the nucleoli as green fluorescence signal within the confines of the highlighted red nuclear fluorescence signal.

Product Specification

Applications:Fluorescence microscopy, Fluorescent detection
Application Notes:For visualizing nucleoli and nuclei simultaneously in living cells.
Quality Control:
  1. Absorption peaks: NUCLEOLAR-ID® Green Detection Reagent: λmax= 439 ± 9 nm NUCLEAR-ID®  Red Detection Reagent: λmax= 566 ± 4 nm
  2. % purity by HPLC: NUCLEOLAR-ID® Green Detection Reagent: ≥ 93%; NUCLEAR-ID® Red Detection Reagent: ≥ 93%
  3. A sample from each lot of TOTAL-NUCLEAR-ID® Green/ Red Nucleolus/Nucleus Detection Kit is used to stain HeLa cells using the procedures described in the user manual. Cells stained with NUCLEOLAR-ID® Green Detection Reagent show maximal fluorescence signal within the nucleoli, with only faint fluorescence throughout the nucleus and cytoplasm. NUCLEAR-ID® Red Detection Reagent maximally stains the DNA in the cell nucleus. Cells induced by actinomycin D show reduction of nucleolar signal.
