Description

Fitc-εahx-Antennapedia Homeobox (43-58) Amide is a fluorescently labeled peptide derivative designed for advanced cellular and molecular biology research. This compound matters as a critical tool for studying protein-protein interactions, intracellular trafficking, and the mechanisms of cell-penetrating peptides (CPPs). Researchers in pharmaceutical development, neurobiology, and proteomics need it for its ability to visualize and quantify the uptake and localization of bioactive peptide sequences within living cells.

Application

• Intracellular Delivery Studies: As a model cell-penetrating peptide (CPP) conjugate for investigating mechanisms of cellular uptake and membrane translocation.
• Live-Cell Imaging: Fluorescent tracer for real-time visualization of peptide internalization and subcellular localization using fluorescence microscopy.
• Drug Delivery Research: Prototype for designing and evaluating novel peptide-based delivery systems for therapeutic cargo (e.g., drugs, nucleic acids).
• Protein-Protein Interaction Analysis: Probe for studying the binding interactions of the Antennapedia homeodomain with target DNA or partner proteins.
• Neuroscience Research: Tool for exploring the role of homeobox proteins in neuronal development and function.
• Flow Cytometry: Fluorophore-labeled agent for quantitative analysis of peptide uptake efficiency across cell populations.
