Cy-5.5

Cy5.5 DBCO, a click chemistry reagent, features a cycloalkyne group and serves as a linker for the Cyanine5.5 fluorophore. Its DBCO group facilitates copper-free, biocompatible click chemistry, characterized by rapid reaction kinetics and high stability [1].

Cy5.5-SE (Cyanine5.5 NHS ester) DIPEA, a cyanine (CY) dye, comprises two nitrogen atoms linked by an odd number of methyl units. Characterized by long wavelength, tunable absorption and emission, high extinction coefficient, and good water solubility, alongside relatively straightforward synthesis [1], CY dyes are frequently utilized for labeling proteins, antibodies, and small molecular compounds. Their application in protein antibody labeling is achieved through a simple mixing reaction, providing a method of notable reference significance [2]. Storage instructions include protection from light.

α-MSH acetate is an endogenous neuromodulatory peptide derived from POMC and an agonist of MC4R (melanocortin receptor 4). It inhibits food intake, fever, and inflammation, exhibiting multiple biological activities.
