Cat. No.: HY-D3274
PE-Cy5 is a tandem fluorescent dye commonly used in flow cytometry, immunofluorescence, and cell biology research. It is formed by the covalent linkage of two fluorescent molecules, namely phycoerythrin and CY5. PE-Cy5 binds to human FcγRI (CD64), and this binding can be blocked by human pooled serum, anti-CD64 monoclonal antibodies targeting the ligand-binding region, or aggregated IgG. PE-Cy5 supports three-color flow cytometry analysis, and whole blood staining can partially reduce its non-specific binding (Ex/Em = 450-500 nm/665 nm) .

Leucocrystal violet is a cationic triarylmethane dye. Leucocrystal violet generates a colored purple product in the presence of hydrogen peroxide and horseradish peroxidase, or when oxidized by periodate under the catalysis of horseradish peroxidase. Leucocrystal violet serves as a chromogenic reagent for the determination of submicrogram-level hydrogen peroxide, with no interference from tryptophan, persulfate or chromate. Leucocrystal violet reacts with blood to produce a purple/violet color in the presence of hydrogen peroxide; it forms a very weak fluorophore when acting with whole blood in an unbuffered solution, with a maximum absorption wavelength of 630 nm and a maximum fluorescence emission wavelength of 665 nm upon excitation at 630 nm.

TOTO-3 is a cyanine nucleic acid intercalating fluorescent probe that binds to both RNA and DNA (Ex=642 nm, Em=660 nm). TOTO-3 cannot enter intact cells, but can penetrate cells with permeabilized plasma membranes, staining cytoplasmic RNA and nucleoli to distinguish intact cells from damaged ones. TOTO-3 is taken up by macrophages in an ultrasound-independent manner. TOTO-3 accumulates in tumor cells via ultrasound-mediated enhancement of plasma membrane permeability. TOTO-3 supports optical imaging for real-time assessment of plasma membrane integrity, nucleic acid detection, and monitoring of ultrasound-mediated intracellular delivery processes. TOTO-3 is applicable to studies related to rectal cancer .
