Acetyl-β-Endorphin (human) 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.

LCMV gp33-41 (TFA), the carboxyl-extended 11-aa-long peptide, is an lymphocytic choriomeningitis virus sequence restricted by MHC class I H-2Db molecules and presented to cytotoxic T lymphocytes.

CY5-SE is a reactive dye for the labeling of amino-groups in peptides, proteins, and oligonucleotides (Excitation: 649 nm, Emission: 670 nm).
