Scientific Background | 5-FAM-RQIKIWFQNRRMKWKK-NH2 is a fluorescently labeled form of the Antennapedia homeodomain-derived cell-penetrating peptide commonly known as penetratin. The 16-residue RQIKIWFQNRRMKWKK sequence has been extensively studied for membrane interaction and cellular internalization. N-terminal FAM enables direct visualization and quantitative uptake studies. |
Research Applications | - penetratin uptake studies
- fluorescence microscopy
- cell-penetrating peptide localization
- membrane interaction research
|
Experimental Notes | FAM labeling may alter uptake, membrane association or intracellular distribution relative to unlabeled penetratin. Protect the fluorescent reagent from light and interpret experiments for the labeled construct. |
