| Description | WL12 is a specifically targeting programmed death ligand 1 (PD-L1) binding peptide. WL12 can be radiolabeled by different radionuclides, generating radiotracers, which can assess the tumor PD-L1 expression[1] | CRT, an iron peptide mimic, can bind to apo-transferrin (apo-Tf). CRT can be used to modify nanoparticles, and enhances drug delivery efficiency[1] | Neuromedin U, rat TFA is a 23-amino acid brain-gut peptide. Neuromedin U (NMU), through its cognate receptor NMUR2 in the central nervous system, regulates several important physiological functions, including energy balance, stress response, and nociception | STh, an Escherichia coli heat-stable toxin, is a 19 amino acid polypeptide encompassing three disulfide bridges. STh is an antigen of interest in the search for a broad coverage enterotoxigenic Escherichia coli (ETEC) vaccine[1] | Submandibular mucin is a high molecular weight glycoprotein that is used as a substrate for the viral enzyme neuraminidase[1] |
