NLS (PKKKRKV) is a peptide derived from the 40 tumor antigen of the great ape virus (SV40 big T antigen), which is a method to enhance the nuclear portal in the research field of gene transfer.

Tetanus toxin (830-843) from tetanus toxoid is a universal human tetanus toxin T cell epitope. It induces T-cell activation and is used as a helper peptide in vaccinations.

pTH (73-84) (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.
