| Targets |
Antennapedia Peptide TFA targets cell membranes, facilitating the intracellular delivery of cargo molecules. As a cell-penetrating peptide, it does not have a specific pharmacological receptor but rather mediates the translocation of conjugated molecules across cellular membranes.

| ln Vitro |
RQIKIWFQNRRMKWKK is the 16 amino acid peptide that makes up Antennapedia Peptide TFA. A 60 amino acid protein called the DNA binding domain of the Drosophila transcription factor, or Antennapedia, is quickly absorbed by cells and has been fused to certain antigens to increase their immunogenicity. Antennapedia Peptide TFA, a 16-amino acid peptide, has the ability to promote the cytoplasmic absorption of cytotoxic T cell epitope 9-mer peptides[1].
In vitro, Antennapedia Peptide TFA promotes the cytoplasmic absorption of cytotoxic T cell epitope 9-mer peptides. It is used to deliver antigens and other cargo molecules into cells for immunological and therapeutic applications. |
| ln Vivo |
In vivo, Antennapedia Peptide TFA can be used to deliver conjugated cargo molecules to cells and tissues. Its cell-penetrating properties make it a valuable tool for studying intracellular delivery of therapeutics and antigens.
|
| Enzyme Assay |
Non-cellular assays for Antennapedia Peptide TFA are not typically performed as it is a cell-penetrating peptide that functions by interacting with cellular membranes. Its activity is assessed in cell-based systems by measuring the uptake of fluorescently labeled peptide or cargo.
|
| Cell Assay |
In vitro cellular assays for Antennapedia Peptide TFA involve treating cells with fluorescently labeled peptide or peptide-cargo conjugates. Cellular uptake is quantified by flow cytometry or fluorescence microscopy. The peptide's ability to deliver cargo to the cytoplasm is confirmed by assessing the biological activity of the delivered molecule.
|
| Animal Protocol |
In vivo animal experiments for Antennapedia Peptide TFA would involve administering the peptide, typically conjugated to a cargo, to animal models. Its ability to deliver the cargo to specific tissues and elicit a biological response would be evaluated.
|
| ADME/Pharmacokinetics |
Pharmacokinetic properties for Antennapedia Peptide TFA are not detailed in available sources. As a cell-penetrating peptide, its PK would be influenced by factors such as stability, proteolytic degradation, and clearance. Its ability to cross biological membranes is a key feature.
|
| Toxicity/Toxicokinetics |
Toxicological data for Antennapedia Peptide TFA are not provided in available sources. As a research peptide, its safety profile has not been extensively characterized. It is intended for research use only and not for human consumption.
