In the expansive field of molecular biology and biochemistry, the term Peptide P1 often surfaces in diverse contexts, ranging from structural research to signal transduction studies. As someone who engages with these materials for investigative purpos CAS No : 959780-73-5 | Product Name : Peptide P1 es, understanding the nuances of these sequences is essential. While the nomenclature can be confusing—often overlapping with unrelated biological entities—a closer look at the specific biochemical properties of P1 reveals its significance in modern laboratory analysis.
Defining Peptide P1: An Analytical Overview
At its core, Peptide P1 is frequently identified as a biological active peptide. In many research settings, it is recognized as an octapeptide (H-GSFLVRES-OH) with a molecular weight of approximately 894 Da. This specific sequence is highly valued for its role as a tool to measure the degree of scrambling during Electron Transfer Dissociation (ETD) analysis.
For those looking to buy highly pure Peptide P1, it is important to verify the CAS number (959780-73-5) and the purity levels, which should generally exceed 95% for reliable experimental outcomes. Unlike some broad-spectrum antimicrobial peptide variants or the well-characterized amphipathic cell penetrating peptide known as PEP-1 (which has 21 amino acid r The Benefits of Peptides: BPC157 & KPV for Healing and Gut Health | LSW esidues), the P1 octapeptide is distinct in its sequence and its specific application as a reference standard.
The Role of P1 in Biological Systems
Research has shown that P1 peptide participates in the signal transduction from the cell surface to the nucleus. This function is facilitated by its role as a highly conserved amino acid sequence that acts as a minimum essential unit in the SRC homology region 2 (SH2) to recognize phosphotyrosine. By suppressing the binding of EGFR to the SH2 domain of phospholipase C-γ, it serves as a critical probe for understanding intracellular communication pathways.
It is important to differentiate this from other similarly named entities. For example, while researchers often discuss peptides in the context of health, it is essential to distinguish P1 from markers like PINP, which is a useful marker in the diagnosis and/or management of metabolic bone diseases, or Glucagon-like peptide-1 (GLP-1), which is a 30- or 31-amino-acid Peptide P1 secondary structure prediction. (A) Three- -long peptide hormone. Furthermore, P1 should not be confused with the P1 bacteriophage used in *E. coli* transduction, nor with specialized variants like LyP-1, which recognizes lymphatics and tumor cells.
Best Practices for Handling and Storage
When working with these sensitive biochemical compounds, maintaining structural integrity is paramount. Based on general laboratory standards for peptide P1, it is recommended to keep solution at +4°C for up to 5 days or freeze at -20°C for up to 3 months. To ensure the highest quality of your samples, always aliquot before freezing to avoid repeated freeze-thaw cycles, which can degrade the molecular structure.
