Description and Research Mechanism
PE-22-28 is a specialized tool for investigating the TREK-1 (TWIK-related potassium) channel, a two-pore potassium channel vital to the nervous economy. This peptide acts as a potent antagonist, focused on the specific amino acid sequence (22 through 28) of the parent spadin molecule. By blocking the TREK-1 channel, PE-22-28 increases neuronal excitability, making it a vital instrument for studying the pathways involved in memory, mood, and emotional regulation.
Beyond its neurological applications, PE-22-28 has demonstrated remarkable potential in studies involving hippocampal neurogenesis. Research indicates that the peptide can stimulate the production of new neurons by influencing the upregulation of Brain-Derived Neurotrophic Factor (BDNF) and CREB phosphorylation. Furthermore, its interaction with muscular mechanoreceptors makes it a candidate of interest for research into muscle physiology and contractility.
This 99% purity, pharmaceutical-grade powder is optimized for stability. Its solubility in deionized water facilitates efficient experimental preparation, ensuring that your research remains consistent and reproducible.
