Invitrogen™ DiO'; DiOC18(3) (3,3'-Dioctadecyloxacarbocyanine Perchlorate)
The green fluorescent, lipophilic carbocyanine >DiOC18(3) is widely used as a lipophilic tracer. It is weakly fluorescent in water, but highly fluorescent and quite photostable when incorporated into membranes.
Invitrogen™ Staphylococcus aureus (Wood strain without protein A) BioParticles™, unlabeled
Unlabeled, heat- or chemically killed bacteria and yeast in a variety of sizes, shapes, and natural antigenicities
Invitrogen™ SYTO™ RNASelect™ Red
SYTO™ RNASelect™ Red is a cell-permeant, RNA-selective fluorescent dye for live or fixed eukaryotic cells. It allows researchers to visualize RNA-rich nucleoli and cytoplasmic RNA in a Texas Red/RFP compatible channel.
Invitrogen™ RH 237 (N-(4-Sulfobutyl)-4-(6-(4-(Dibutylamino)phenyl)hexatrienyl)Pyridinium, Inner Salt)
Fast-response potential-sensitive probe

Invitrogen™ Sulforhodamine B
Water-soluble, nonfixable red fluorescent (excitation/emission maxima approximately 565/586nm) polar tracer
Invitrogen™ Dextran, Tetramethylrhodamine, 10,000 MW, Lysine Fixable (fluoro-Ruby)
Rigorous methods for removing as much unconjugated dye as practical, followed by an assay of dextran conjugates by thin-layer chromatography to help ensure the absence of low molecular weight contaminants
Invitrogen™ Dextran, Fluorescein, 10,000 MW, Anionic, Lysine Fixable (Fluoro-Emerald)
Rigorous methods for removing as much unconjugated dye as practical, followed by an assay of dextran conjugates by thin-layer chromatography to help ensure the absence of low molecular weight contaminants
