Description

H-Arg-Arg-Arg-Arg-Arg-Arg-Oh Trifluoroacetate Salt is a synthetic, high-purity hexa-arginine peptide derivative, essential for advanced biochemical and pharmaceutical research. This compound serves as a critical tool for studying cell-penetrating peptides (CPPs), drug delivery mechanisms, and protein-protein interactions due to its strong cationic charge and membrane permeability. It is primarily utilized by researchers and developers in the life sciences, pharmaceutical R&D, and biotechnology sectors for applications ranging from novel therapeutic vector design to fundamental biomolecular studies.

Application

• Cell-Penetrating Peptide (CPP) Research: Fundamental studies on the mechanisms of cellular uptake and intracellular delivery of bioactive molecules.
• Drug Delivery Vector Development: Design and testing of novel carrier systems for the targeted delivery of oligonucleotides, proteins, and other therapeutic agents.
• Bioconjugation & Protein Labeling: Acts as a cationic linker or tag to modify the properties of biomolecules for imaging, diagnostics, or therapeutic purposes.
• Biomaterial & Surface Functionalization: Coating or modifying surfaces to promote cell adhesion, growth, or specific biological interactions in tissue engineering.
• Inhibitor & Agonist Studies: Investigation of biological pathways where poly-arginine sequences play a role, such as in nitric oxide synthase regulation.
• Pharmaceutical Reference Standard: Serves as a high-purity analytical standard for quality control and method development in peptide synthesis and analysis.
