red fluorescent dye

Cy5-DBCO is a near-infrared, anthocyanine fluorescent dye Cy5 (Cyanine 5) derivative with an excitation wavelength of 650 nm and an emission wavelength of 670 nm.DBCO-Sulfo-Cy5 contains a DBCO moiety, which can undergo SPAAC click chemistry with molecules that contain Azide moieties.

JC-1 (CBIC2) is a fluorescent lipophilic cyanine dye. JC-1 is used to measure mitochondrial membrane potential. When the mitochondrial membrane potential is high, JC-1 aggregates into polymers within the matrix, emitting red fluorescence (λex=585 nm, λem=590 nm). When the mitochondrial membrane potential is low, JC-1 fails to aggregate within the mitochondrial matrix and exists as monomers, emitting green fluorescence (λex=510 nm, λem=527 nm).

PKH 26 is a red-fluorescent membrane dye, Ex/Em=551/567 nm.PKH 26 is commonly used in flow cytometry to measure T cell-mediated cytotoxic activity.

MitoSOX Red is a fluorescent dye serving as a mitochondria-targeted fluorescent probe for superoxide, with cell membrane permeability and specificity. Upon oxidation, MitoSOX Red subsequently binds to nucleic acids within mitochondria/nuclei, producing intense red fluorescence, and is employed for detecting mitochondrial superoxide in live cells.

Alexa fluor 647 NHS ester (L-5-Hydroxytryptophan-d3) is a photostable far-red fluorescent dye used in imaging and flow cytometry to generate stable signals for protein labeling, amine-modified oligonucleotides, and other primary amine-containing molecules.

Nile Red ((Nile Blue A oxazone)) is a lipophilic, environment-sensitive fluorescent dye. Highly hydrophobic, with fluorescence significantly enhanced in lipid-rich environments. Commonly used for specific staining of intracellular lipid droplets, with excitation/emission wavelengths of 559/635 nm.

Sulforhodamine B sodium salt (Acid Red 52) is a fluorescent dye. It can be used from laser-induced fluorescence to the quantification of cellular proteins of cultured cells.

Acridine Orange base is a cell-permeable fluorescent dye that binds to nucleic acids and emits different colors of fluorescence, which exhibits green fluorescence when bound to dsDNA (Ex=488 nm, Em=520-524 nm) and red fluorescence when bound to ssDNA or ssRNA (Ex=457 nm, Em=630-644 nm) and can be used for cell cycle analysis and apoptosis detection.

Nuclear Fast Red is an anthraquinone dye that serves as a red nuclear counterstain when aluminum ions are present in excess, thereby aiding in histological visualization of nuclear components. Nuclear Fast Red additionally functions as a histochemical and colorimetric reagent for calcium detection,Nuclear Fast Red further acts as a highly sensitive “off/on” fluorescent probe for the detection of guanine, making it a multifunctional research reagent.

TMRM Perchlorate (T668) is a cell-permeant cationic lipophilic red fluorescent dye (λex=530 nm, λem=592 nm).

TMRM is a cell-permeant cationic lipophilic red fluorescent dye (λex: 530 nm, λem: 592 nm).

Cyanine3 NHS Ester Chloride is an amine-reactive orange-red fluorescent dye and the NHS ester derivative of Cyanine3, supplied as a chloride salt. Its N-hydroxysuccinimide (NHS) ester reacts efficiently with primary amines on proteins, antibodies, or other biomolecules under neutral to slightly basic conditions, forming stable amide bonds. This dye is widely used for cellular labeling, flow cytometry, and biomolecular staining studies.

DBCO-Cy3 (DBCO-Sulfo-Cy3) is a modified cyanine-3 and orange-red fluorescent dye that can undergo SPAAC click chemistry reactions with azide groups. It has an excitation wavelength of 555 nm and an emission wavelength of 580 nm.

Sulforhodamine 101 (SR101) is a red fluorescent dye.

C.I. Disperse Red 15 is a red dye. C.I. Disperse Red 15 is used as a fluorescent indicator.

JFX 650, NHS ester, a deuterated red fluorescent Janelia Fluor® dye, is provided with an NHS ester reactive group for labeling primary amines. It is ideal for live cell imaging.

Janelia Fluor 635, Haloalkane, a red cell-permeable fluorogenic fluorescent dye featuring a chloroalkane handle, exhibits significant fluorogenicity. The excitation and emission maxima (λ) for this compound are 635 nm and 652 nm, respectively, with a quantum yield of 0.56.

Janelia Fluor 646, Haloalkane, a red cell-permeable fluorogenic fluorescent dye featuring a chloroalkane handle, exhibits significant fluorogenicity. The excitation and emission maxima (λ) for this compound are 646 nm and 664 nm, respectively, with a quantum yield of 0.54.

DQ-BSA-RED is a red-fluorescent-labeled bovine serum albumin (BSA) derivative specifically designed for monitoring lysosomal proteolytic activity. DQ-BSA-RED can be used for live-cell imaging or for observation following formaldehyde fixation. DQ-BSA-RED exhibits excitation and emission maxima at 590 nm and 620 nm, respectively, and contains multiple dye moieties resulting in fluorescence self-quenching until proteolytic cleavage occurs within lysosomes, upon which bright fluorescence is emitted. DQ-BSA-RED therefore enables the visualization and quantification of lysosomal functionality in live-cell assays, while inactive lysosomes fail to generate fluorescence, providing a valuable tool for studying autophagy and intracellular degradation processes.
