Em 601-630 nm Orange

5-ROX (5-Carboxy-X-rhodamine), a rhodamine dye, exhibits strong fluorescence in aqueous buffer with an excitation wavelength (λexit) of 580 nm (ε = 3.6×10^4 (M·cm)) and an emission wavelength (λemit) of 604 nm (ϕ = 0.94).

Sulforhodamine 101 (SR101) is a red fluorescent dye.

2-Di-1-ASP is a mono-stryryl dye and widely used as mitochondrial stain and groove-binding fluorescent probes for double-stranded DNA. It has selective for G-quadruplex (G4) and double-stranded DNA.

Dihydrofluorescein diacetate (Diacetyldihydrofluorescein) is a fluorescent probe for measuring oxidative stress in cell-free systems and cellular models.

5(6)-ROX, a nucleic acid fluorescent label, serves as a reference dye in real-time polymerase chain reaction (PCR) applications.

Cyamine3.5 NHS ester is a squaraine dye utilized in the development of fluorescent probes and biological labeling, characterized by its intermediate wavelength fluorescence emission properties. Specially designed for reactions with amino groups to form stable covalent bonds, it is ideal for labeling biomolecules. Ex Em(nm)=591 604.

BDP 581 591 NHS ester, a borondipyrromethene dye (Ex=585 nm, Em=594 nm), exhibits a relatively long fluorescence lifetime and significant two-photon excitation cross-section. This compound is applicable in fluorescence polarization analysis, interacts with reactive oxygen species (ROS) to modify fluorescence, and, as an NHS ester derivative, binds to the primary and secondary amine groups of proteins, peptides, and various molecules. Storage instructions highlight the importance of protecting it from light.

TAMRA-probe 1 is a fluorescent probe for labeling.

Ethidium monoazide bromide, a fluorescent dye that intercalates with DNA, selectively penetrates bacteria possessing compromised membranes. Upon photoactivation, it forms covalent bonds with DNA, enabling it to exclusively stain dead cells [1].
