STEMCELL Technologies GloCell™ Fixable Viability Dye Red 780, Size: 100 Tests
GloCell™ Fixable Viability Dye Red 780 is a fluorescent cell viability dye for staining live/dead mammalian cells in applications such as flow cytometry. The dye irreversibly binds intracellular and cell surface amine groups and can be utilized prior to fixation, permeabilization, or cryopreservation. Cells with compromised plasma membranes become permeable to the GloCell™ dye, resulting in a greater fluorescence compared to live cells in a cell viability assay.GloCell™ Fixable Viability Dye Red 780 is excited by the red laser at 633 nm and it has a fluorescence emission maximum of 780 nm that can be detected using the 780/60 band pass filter used to detect APC-Cy7.
AdipoGen Rhodamine 800
Chemical. CAS 137993-41-0. Formula C26H26ClN3O5. MW 495.95. Rhodamine 800 is a near-infrared fluorescent dye, which was originally developed as a laser dye. Rhodamine 800 belongs to the rhodamine family and is one of the few rhodamines that have near infrared fluorescence. It displays bright red-orange fluorescence, making it an ideal choice for labeling proteins, nucleic acids, and other molecules in biochemical studies. Rhodamine 800 finds widespread use in research and analytical applications. It is used for detecting proteins in cells, tracking molecule movement and studying molecular interactions. In fluorescence microscopy and imaging, Rhodamine 800 enables visualization of organelles and molecules within living cells. It proves valuable in flow cytometry for measuring DNA levels and quantifying proteins and other molecules.

Aat Bioquest 5-FAM SE [5-Carboxyfluorescein succinimidyl ester] CAS 92557-80-7 (100 mg)
5-FAM SE is the amine-reactive succinimidyl ester of single isomer 5-FAM acid. This catalog is for 100 mg.
LICOR IRDye QC-1 NHS Ester (0.5 mg)
IRDye QC-1 is the first non-fluorescent (dark) quencher compatible with a wide range of visible and near-infrared fluorophores (~500-800 nm). It has the widest available quenching range, so you do not need to carefully match the donor's fluorescence spectrum with the acceptor's absorbance. IRDye QC-1 NHS ester can be used for FRET (fluorescence resonance energy transfer) applications such as protease assays. Recently, it has been paired with IRDye 800CW in optoacoustic studies.
