Cell-Permeable Peptides for Research and Therapeutic Applications
Cell-permeable peptides (CPPs) have emerged as powerful tools in biomedical research and therapeutic development. These short peptide sequences possess the unique ability to cross cellular membranes, delivering bioactive cargoes into cells with high efficiency. The growing interest in buy cell-permeable peptides reflects their expanding applications across multiple scientific disciplines.
What Are Cell-Permeable Peptides?
CPPs, also known as protein transduction domains, typically consist of 5-30 amino acids. Their structure enables them to traverse plasma membranes through various mechanisms, including direct penetration and endocytosis. Common examples include TAT (from HIV-1), penetratin, and polyarginine sequences.
Key Advantages of Using CPPs
Researchers choose to buy cell-permeable peptides for several compelling reasons:
- Efficient intracellular delivery of various cargoes (proteins, nucleic acids, drugs)
- Low cytotoxicity compared to other delivery methods
- Broad applicability across different cell types
- Potential for in vivo applications
Research Applications
Scientists utilize CPPs in numerous research areas:
