HY-D1871

Cy3 maleimide chloride	Fluorescent Dye	Others
Cy3 maleimide chloride is a dye derivative of Cyanine 3 (Cy3) (HY-D0822) containing maleimide functional groups. Cy3 is a fluorescent dye with a fluorescence spectrum typically in the green to orange wavelength range. The alkyne functional group of Cy3 maleimide chloride can undergo a "thiol-acrylamide" reaction with molecules containing sulfur-oxygen functional groups to form covalent bonds. Cy3 maleimide chloride can bind to biological molecules such as proteins and antibodies to track their location and dynamic changes in biological samples.

HY-137098

*Sulfo-Cy3* maleimide potassium**	Fluorescent Dye	Others
Sulfo-Cy3 maleimide potassium is a fluorescent dye with a maleimide functionality at the end a short alkyl linker. Sulfo-Cy3 maleimide potassium can be used for the labeling of antibodies and other labile proteins .

HY-D2231

**Cy3.5 maleimide**	ADC Cytotoxin	Others
Cy3.5 maleimide is a relatively water-soluble fluorescent dye. Cy3.5 maleimide is soluble in organic solvents, including DMF, DMSO and acetonitrile and so on .

HY-D2239

Sulfo-Cy3.5 maleimide	Fluorescent Dye	Others
Sulfo-Cy3.5 maleimide is sulfonated modified Cy3.5 with good water solubility. λex=591 nm, λem=604 nm .

HY-172721

**Cy3B maleimide**	Fluorescent Dye	Others
Cy3B maleimide is a mono-reactive dye containing maleimide group, which can selectively and efficiently attach Cyanine3 fluorophore (an analog of Cy3) to proteins and peptides containing cysteine residues, as well as to other thiolated molecules (such as thiol-containing oligonucleotides). Cy3B is an improved version of Cy3 dyes with significantly increased fluorescence quantum yield and photostability.

HY-D2509

Cy3-PEG-SH (MW 1000)	Fluorescent Dye	Others
Cy3-PEG-SH (MW 1000) is a fluorescent labeling reagent that combines Cy3 (HY-D0822) fluorescent dye, polyethylene glycol (PEG) and sulfhydryl (SH) derivatives, and is suitable for molecular coupling. SH is highly reactive and can react with a variety of functional groups (such as maleimide) to form stable thioether bonds .

HY-D2512

Cy3-PEG-SH (MW 5000)	Fluorescent Dye	Others
Cy3-PEG-SH (MW 5000) is a fluorescent labeling reagent that combines Cy3 (HY-D0822) fluorescent dye, polyethylene glycol (PEG) and sulfhydryl (SH) derivatives, and is suitable for molecular coupling. SH is highly reactive and can react with a variety of functional groups (such as maleimide) to form stable thioether bonds .
