Description

Semax

Semax is a high-potency synthetic heptapeptide and a stabilized analog of the ACTH (4-10) fragment (Met-Glu-His-Phe-Pro-Gly-Pro). In the landscape of neuroscience and regenerative research, Semax is primarily recognized for its profound neurotrophic and neuroprotective properties. Unlike traditional stimulants, Semax operates by modulating the expression of Brain-Derived Neurotrophic Factor (BDNF) and Nerve Growth Factor (NGF) within the hippocampus and cerebral cortex. It provides researchers with a robust experimental tool to investigate neuronal survival, synaptic plasticity, and the acceleration of recovery in models of ischemic brain injury and neurodegenerative decline.

Our Semax is synthesized in an ISO 9001:2015 certified and GMP-grade manufacturing environment. By utilizing advanced Solid-Phase Peptide Synthesis (SPPS) and rigorous multi-stage HPLC purification, we achieve an ultra-high chemical purity of ≥99%. This meticulous production standard ensures the peptide is free from truncated fragments and residual chemical reagents, guaranteeing the consistency required for high-resolution studies into neurotransmitter balance and cerebral blood flow regulation.

Key Features & Quality Assurance

Pharmaceutical-Grade Lyophilization

Our proprietary vacuum-sealing process ensures the Semax powder surface is perfectly smooth, flat, and delicate. This uniform “cake” structure ensures rapid reconstitution and protects the heptapeptide from molecular degradation during long-term storage.

Enhanced Molecular Stability

By incorporating the Pro-Gly-Pro sequence at the C-terminus, our synthetic Semax is engineered for increased resistance to enzymatic degradation, allowing for sustained activity in research media.

Reconstitution & Storage

Reconstitution Guide

• Preparation: Allow the vial to reach room temperature. Centrifuge for 30-60 seconds to ensure the Semax cake is at the base.

• Solvent: Reconstitute with Sterile Water or Bacteriostatic Water.

• Technique: Gently introduce the diluent against the vial wall. DO NOT SHAKE; swirl gently until the solution is clear and transparent.

Storage Protocols

• Long-term: Store at -20°C (Maintains potency for up to 24 months).

• Short-term: Stable at 2–8°C for up to 3 months.

• Post-Reconstitution: Store at 2–8°C and utilize within 10-14 days.
