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.
