Qnuclear™ Deep Red Stain (Invitrogen™)

Qnuclear™ Deep Red stain is a highly selective nuclear counterstain designed for use with cells labeled with Qdot® 525, 565, 585, 605 and 625 nanocrystals and mounted in Qmount™ Qdot® Mounting Media (Q10336).

Image-IT™ LIVE Lysosomal and Nuclear Labeling Kit (Counterstains For GFP-Expressing Cells) (Invitrogen™)

The Image-iT™ LIVE Lysosomal and Nuclear Labeling Kit provides two stains - red-fluorescent LysoTracker® Red DND-99 dye and blue-fluorescent Hoechst 33342 dye - for highly selective staining of lysosomes and the nucleus, respectively, in live green-fluorescent protein (GFP)-transfected cells. When used according to the sample protocol, cell-permeant LysoTracker Red DND-99 provides highly selective lysosomal staining with minimal background. Hoechst 33342 dye, a cell-permeant nucleic acid stain that is selective for DNA and spectrally similar to DAPI, is UV excitable and emits blue fluorescence when bound to DNA. This dye should not interfere with GFP fluorescence and is retained after fixation and permeabilization.

Image-IT™ LIVE Intracellular Membrane and Nuclear Labeling Kit (Counterstains For GFP-Expressing Cells) (Invitrogen™)

The Image-iT™ LIVE Intracellular Membrane and Nuclear Labeling Kit provides two stains - red-fluorescent CellTrace™ BODIPY® TR methyl ester and blue-fluorescent Hoechst 33342 dye - for highly selective staining of the intracellular membranes and nuclei of live green-fluorescent protein (GFP)-transfected cells and tissues.

Image-IT™ LIVE Plasma Membrane and Nuclear Labeling Kit (Counterstains For GFP-Expressing Cells) (Invitrogen™)

The Image-iT™ LIVE Plasma Membrane and Nuclear Labeling Kit provides two stains - red-fluorescent Alexa Fluor® 594 wheat germ agglutinin (WGA) and blue-fluorescent Hoechst 33342 dye - for highly selective staining of the plasma membrane and nucleus, respectively, of live green-fluorescent protein (GFP)-transfected cells.
