Calcitonin (rat) is a polypeptide that can be found by peptide screening. Peptide screening is a research tool that pools active peptides primarily by immunoassay. Peptide screening can be used for protein interaction, functional analysis, epitope screening, especially in the field of agent research and development.

Uroguanylin (human) is a natural ligand for the Guanylyl Cyclase (GCC) receptor expressed in metastatic colorectal cancer tumors. Uroguanylin (human) has anti-tumor actions in an animal model for human colon cancer.

VIR-165 is a modified form of virus inhibitory peptide (VIRIP), which corresponds to residues 353 to 372 of C-proximal region of human alpha1-antitrypsin, the most abundant circulating serine protease inhibitor. VIRIP inhibits a wide variety of human immunodeficiency virus type 1 (HIV-1) strains.
