Cy3 NHS ester is a fluorescent dye used to label amino groups in proteins, peptides, antibodies, and oligonucleotides. The excitation/emission (Ex/Em) values ??of Cy3 NHS ester are 550 nm/570 nm.

Leritrelvir (RAY1216) is a potent orally active inhibitor of the SARS-CoV-2 main protease, exhibiting a slow-tight binding mechanism with an inhibition constant (Ki) of 8.6 nM .

Galantide, a non-specific galanin receptor antagonist, is a peptide consisting of fragments of galanin and substance P. Galantide recognizes two classes of galanin binding sites (KD<0.1 nM and ~6 nM) in the rat hypothalamus. Galantide dose dependently (IC50=1.0 nM) antagonizes the galanin-mediated inhibition of the glucose-induced insulin secretion from mouse pancreatic islets. Galantide appears to bind to a single population of SP receptors (KD~40 nM).
