Description

Penetratin is a cell-penetrating peptide (CPP) renowned for its ability to efficiently transport various cargo molecules across biological membranes. This capability makes it an invaluable tool in pharmaceutical research and development for enhancing the cellular uptake of therapeutic agents. It is primarily utilized by researchers and manufacturers in the biotechnology, pharmaceutical, and life sciences sectors for drug delivery applications.

Application

• Enhancing the intracellular delivery of therapeutic peptides, proteins, and oligonucleotides.
• Facilitating the transport of small molecule drugs across the blood-brain barrier (BBB) for central nervous system (CNS) targeting.
• Improving the cellular uptake of contrast agents and imaging probes for diagnostic applications.
• Utilized as a key component in the development of novel drug delivery systems (DDS) and nanocarriers.
• Fundamental research tool for studying membrane translocation mechanisms and cell biology.
• Potential use in cosmeceuticals for the transdermal delivery of active ingredients.
