Antennapedia Peptide TFA is a 16 amino acid peptide (RQIKIWFQNRRMKWKK). The DNA binding domain of the Drosophila transcription factor (Antennapedia), a 60 amino acid protein, is rapidly taken up by cells and has been fused to selected antigens to enhance their immunogenicity. A 16 amino acid peptide Antennapedia Peptide TFA from Antennapedia can facilitate the cytoplasmic uptake of cytotoxic T lymphocyte epitope 9-mer peptides.

Quaternary ammonium analog of ethidium; an intercalating dye with a specific affinity to certain forms of DNA and, used as diiodide, to separate them in density gradients.

Methyl nomilinate from citrus can modulate cell cycle regulators to induce cytotoxicity in human colon cancer (SW480) cells in vitro.
