Biotium CellBrite™ NIR750 Cytoplasmic Membrane Dye, 2 mM in DMSO
CellBrite™ NIR Cytoplasmic Membrane Dyes are novel near-infrared carbocyanine dyes for labeling the cytoplasmic membranes of living cells. Due to their long emission wavelengths, near-infrared cell membrane stains can be used to label cells for near-infrared small animal imaging studies for non-invasive imaging of cell migration and cell homing. The dyes have long 18-carbon hydrophobic tails and an additional water-soluble group. These unique chemical structure elements make the dyes easy to dissolve while providing highly stable cytoplasmic membrane staining, unlike traditional carbocyanine dyes like DiI, DiO, and DiR, which are often difficult to dissolve or prone to precipitation during cell staining. CellBrite™ NIR750 has an excitation/emission of 748/780 nm.
Abcam Rhodol, 5MG
MW 331.3 Da, Purity >95%. Highly fluorescent dye useful for labeling oligonucleotide, antibody and protein studies and for the preparation of peptide and esterase substrates. Rhodol is a structural hybrid of fluorescein and rhodamine. It retains the pH-sensitive properties conferred by a phenolic hydroxyl group, but the amine substituent reduces the pKa values. Rhodol exhibits a high extinction coefficient (~70,000 cm-1M-1) and high quantum yield (~0.8-0.9) in aqueous solution, with absorption maxima at approximately 490 nm and emission maxima between 520 and 545 nm. As with fluorescein-based dyes, the fluorescence excitation profiles of rhodol-based dyes are pH dependent, which can be useful for ratiometric pH determinations intracellularly.

Medchemexpress LLC (±)-ANAP hydrochloride | 2308035-47-2 | 98.5% | 308.76 | C15H17ClN2O3 | 10 MG
(±)-ANAP hydrochloride is a fluorescent, unnatural amino-acid analog of prodan used as an environment-sensitive probe in biochemical and biophysical studies. It displays polarity-dependent changes in fluorescence intensity and emission wavelength, allowing monitoring of local microenvironments when incorporated site-specifically into peptides or proteins. The compound is supplied as a solid hydrochloride salt with storage recommendations to minimize exposure to moisture and light.
- Sensitive to polarity with changes in intensity and emission wavelength.
- Suitable for site-specific incorporation into peptides and proteins.
- Enables monitoring of local microenvironmental changes.
- High purity appropriate for research applications.
- Stable as a solid; store sealed away from moisture and light at 4°C.
- Available in small package sizes for screening and synthesis.
