FAM HIV-1 tat Protein (47-57)

Product Name
FAM HIV-1 tat Protein (47-57)
Product Quantity
1 mg

Product Description

This is the most characterized fragment of the HIV transactivator protein (TAT) YGRKKRRQRRR. The TAT peptide is rich in positively charged amino acids, notably arginine and lysine, which enable it to interact with negatively charged components of the cell membrane. This interaction facilitates its internalization into cells, primarily through endocytosis, although direct translocation mechanisms have also been proposed.

The conjugation of the TAT peptide with a fluorescent dye, such as 5(6)-carboxyfluorescein (FAM), results in FAM-YGRKKRRQRRR, a fluorescently labeled CPP. This modification allows researchers to visually track the peptide's cellular uptake and distribution using fluorescence-based techniques.

  • Applications:

    • Cellular Imaging: FAM-TAT enables real-time visualization of peptide internalization and intracellular trafficking.

    • Quantitative Uptake Studies: Fluorescence intensity measurements facilitate the quantification of peptide uptake in different cell types.

    • Cargo Delivery Tracking: When conjugated to therapeutic agents, FAM-TAT allows monitoring of cargo delivery efficiency.

  • Advantages:

    • Non-Invasive Monitoring: Fluorescence labeling permits non-destructive observation of live cells.

    • High Sensitivity: FAM's strong fluorescence provides sensitive detection of peptide localization.

  • Considerations:

    • Photobleaching: FAM is prone to photobleaching, which can affect long-term imaging studies.

    • pH Sensitivity: The fluorescence intensity of FAM can be influenced by pH changes, potentially impacting quantitative analyses.
