PE-22-28 Peptide 10mg – TREK-1 Channel Inhibition & Hippocampal Signaling Research
A specialized spadin-derived peptide. Optimized for research into TREK-1 channel inhibition, rapid mood regulation pathways, and neurological resilience.
Description
What is PE-22-28 Peptide & CAS 1192800-47-5?
In the advancing field of neuropsychiatric research, PE-22-28 is identified as a potent, synthetic derivative of the naturally occurring peptide “Spadin.” Registered under CAS 1192800-47-5, this 7-amino acid sequence is a truncated version of the Sortilin-derived peptide, specifically engineered for improved stability and higher affinity for its biological targets. In laboratory environments, it is recognized as a primary subject for research into rapid-acting mood regulation and the biological mechanisms of neurological resilience.
The chemical integrity of our PE-22-28 10mg (and 5mg) vials is strictly preserved through a high-fidelity lyophilization process. This professional freeze-drying technique stabilizes the peptide structure into a vacuum-sealed white cake, preventing structural degradation during global transit. At 99Purity-Peptide, we provide a clinical-grade research medium designed for high-precision data collection in studies involving neuro-cognitive optimization and synaptic health.
PE-22-28 Mechanism of Action and Research
Operating as a selective antagonist, PE-22-28 primarily targets the TREK-1 (TWIK-related K+ channel 1) potassium channels. In a laboratory environment, this interaction is uniquely researched for its ability to inhibit TREK-1, which is heavily expressed in the hippocampus and other regions associated with emotional processing. Unlike traditional agents that may take weeks to show results, research into PE-22-28 focuses on its potential for rapid-onset mood stabilization and its role in promoting hippocampal neurogenesis.
Deepening the investigation into neuro-optimization, contemporary trials utilize PE-22-28 to evaluate its efficacy in enhancing neuronal survival and synaptic plasticity under physiological stress. Emerging data from high-fidelity laboratory trials suggests that the blockade of TREK-1 channels by PE-22-28 may provide unique insights into the regulation of neurotransmitter release and cellular recovery. Its inclusion in the neuro-cognitive-optimization category highlights its pivotal role in research involving holistic neurological restoration.

PE-22-28 Peptide FAQ
How does PE-22-28 differ from standard Spadin in research?
PE-22-28 is a shortened, more stable fragment of the Spadin peptide. In research models, it has demonstrated a higher affinity for TREK-1 channels and a better ability to withstand enzymatic breakdown, making it a more efficient tool for studying rapid neurological responses.
What is the role of TREK-1 channels in neuro-optimization?
TREK-1 channels help regulate the electrical excitability of neurons. Research focuses on inhibiting these channels with PE-22-28 to understand how altering potassium flow can lead to improved neurogenesis and enhanced mental resilience.
What is the recommended reconstitution protocol for PE-22-28 10mg?
To maintain 99% purity, researchers use sterile bacteriostatic water. The liquid should be added slowly along the side of the vial. Swirl gently—never shake—until the lyophilized cake is fully dissolved into a clear solution to prevent denaturing the peptide chain.
How should PE-22-28 be stored to maintain high purity?
For long-term storage, the lyophilized powder should be kept at -20°C. Once reconstituted, the solution is highly sensitive to temperature and should be refrigerated at 2-8°C and utilized within the designated experimental window.
Can PE-22-28 be used in studies involving neurogenesis?
Yes, a significant branch of PE-22-28 research explores its ability to stimulate the growth of new neurons in the hippocampal region. It is a valuable subject for investigating recovery from neurological fatigue and cellular aging.
