Variante

N‑Acetil Selank / Semax es una formulación sintética de péptidos duales para investigación que combina dos análogos de péptidos neuroactivos bien caracterizados en una única preparación analítica. Selank, un heptapéptido análogo del péptido inmunomodulador tuftsina modificado con N‑acetilación para una estabilidad mejorada, y Semax, un heptapéptido sintético derivado de un fragmento de la hormona adrenocorticotrópica (ACTH), son ampliamente estudiados en neurobiología, señalización de péptidos e investigación de estructura-función. Cuando se combinan, esta formulación se examina comúnmente en entornos de laboratorio para evaluar las interacciones péptido-receptor, la dinámica de las vías de señalización y el comportamiento comparativo de los neuropéptidos bajo condiciones experimentales controladas. Cada componente tiene una secuencia de aminoácidos definida e identidad molecular documentada, mientras que el producto terminado se clasifica como una mezcla de múltiples péptidos en lugar de una única entidad química.

Scientific Background

Discovery and Development
Semax is a synthetic heptapeptide derived from a fragment of adrenocorticotropic hormone (ACTH). It was developed in Russia in the 1980s and 1990s as a neuroprotective and nootropic agent. Selank is a synthetic heptapeptide analog of tuftsin, also developed in Russia during the same period, primarily studied for its anxiolytic and immunomodulatory effects. The N-Acetyl versions (N-Acetyl Semax Amidate and N-Acetyl Selank Amidate) were later modified with N-terminal acetylation and C-terminal amidation to improve metabolic stability and resistance to enzymatic breakdown, making them more suitable for research use. The combination of these two stabilized peptides emerged as researchers explored potential synergistic effects on cognitive function, stress response, and neuroprotection.

Key Milestones in Research

1980s–1990s: Development of Semax and Selank in Russia for neuroprotective and anxiolytic research.
2000s–2010s: Introduction of acetylated and amidated versions to enhance stability for laboratory studies.
2010s–Present: Growing research interest in combining N-Acetyl Selank and N-Acetyl Semax to study synergistic effects on cognition, anxiety, and brain function.

This blend remains a valuable research tool for investigators studying neuropeptide signaling, stress adaptation, and cognitive enhancement pathways.

Why researchers choose Ceritide Research N-Acetyl Selank + Semax Blend: High-purity stabilized neuropeptide combination ideal for nootropic, neuroprotective, and stress-related research.

Storage Guidelines

Peptide Storage Guidelines: Best Practices for Research Stability

At Ceritide Research, we provide high-purity peptides for laboratory and scientific research. Proper storage preserves peptide integrity and supports reliable experimental results.

Storage Guidelines for Lyophilized (Powder) Peptides

Long-Term Storage: Keep at -20°C (-4°F) or lower (ideally -80°C / -112°F) for multi-year stability.
Short-Term Storage: Refrigerate at 2–8°C (36–46°F) for weeks to a few months. Minimize room temperature exposure.
Best Practices: Store in airtight vials with desiccants. Allow vials to reach room temperature in a desiccator before opening. Protect from light and moisture. Aliquot to reduce freeze-thaw cycles.

Storage Guidelines for Reconstituted Peptide Solutions

Once dissolved, peptides are less stable and should be used promptly:

Recommended Temperature: Store at 2–8°C (36–46°F) (refrigerator) for short-term use, typically up to 1–4 weeks depending on the sequence and buffer.
Longer-Term Solution Storage: Aliquot and freeze at -20°C (-4°F) or lower. Avoid storing solutions long-term when possible.
Best Practices: Use sterile techniques, bacteriostatic water or research-grade buffers, and minimize exposure to air and light. Prevent repeated freeze-thaw cycles.

For Research Use Only
All products from Ceritide Research are sold for research, laboratory, or analytical purposes only, and are not for human consumption. Our peptides are intended exclusively for in vitro scientific research and are not for human or veterinary use.
