Lab Preparation Guide
All preparation operations need to be finished inside ventilated standard laboratory space:
- Prepare qualified lab solvent according to self-designed experimental scheme
- Add solvent into clean lab container first, then add Selank powder slowly, stir gently at room temperature until full dissolution to form homogeneous solution
- Split prepared solution into multiple sealed experimental containers based on experimental dosage requirement
- Unused residual raw powder shall be sealed tightly and transferred to specified low-temperature storage promptly
- Post-experiment waste liquid and leftover residues shall be disposed complying with local laboratory chemical waste management rules
Important Notes
- This commodity is only professional research raw material for laboratory scientific test, forbidden for oral intake, food processing and any commercial daily application.
- Wear protective gloves and eye protection equipment during whole operation to avoid direct long-time contact of powder or solution with skin and eyes.
- Do not place raw material exposed to open air for long time to prevent deliquescence and property change.
- Keep goods away from children and domestic pets to avoid accidental contact

The below operating specifications are only suitable for laboratory scientific research and sample preparation work. This product cannot be used for human & animal application, food processing, cosmetic and medical production.
1.Pre-operation Preparation
Carry out all operations inside clean, dry and well-ventilated lab space. Use standard lab containers, measuring tools and protective supplies to guarantee dust-free operating environment and avoid impurity cross-contamination.
2.Sample Dissolution & Preparation
Select appropriate laboratory solvent based on your own experimental scheme and relevant research literature. Add required solvent into clean container first, then add Selank lyophilized powder, stir mildly at room temperature until all powder fully dissolves to form uniform transparent liquid. The mixing dosage and solution concentration can be adjusted flexibly according to different experiment designs.
3.Subpackage & Temporary Storage
After solution preparation is finished, divide the liquid into multiple sealed lab containers as per experiment dosage demand. Seal leftover unused raw powder tightly right after sampling to isolate air and moisture, then store under designated low-temperature condition promptly to maintain raw material stability.
4.Waste Disposal after Experiment
All residual liquid, waste samples and experimental residues need classified disposal following local laboratory chemical waste management regulations, random dumping is forbidden.
Important Notes
- This item is exclusive laboratory research raw material, oral intake, food manufacture and daily commercial usage are strictly prohibited.
- Wear protective gloves and eye shield during full operating process to prevent long-term direct contact between raw material and human skin or eyes.
- Never leave raw material exposed in open air for long time to avoid moisture absorption, caking and property variation.
- Keep the goods far away from children and pets to prevent accidental touching.

ECHEMI Editorial Reference
Selank is a synthetic derivative of the tetrapeptide tuftsin that contains a proline-glycine-proline sequence at the C-terminus and has anxiolytic and anti-inflammatory activities. It increases the amplitude and discharge rate of inhibitory postsynaptic currents of neurons in the rat hippocampal CA1 region when used at a concentration of 1 μM. It decreases the level of affective responses and the number of erroneous escape attempts in rats in an acute stress situation, increases orientational-investigative responses of rats in an unfamiliar situation, and reduces the time mice spend immobile in the forced swim test. It increases locomotor activity of high-anxiety Balb/c, but not C57Bl/6, mice in the open field test. Selank (0.01 mg/kg) decreases verticalization induced by apomorphine in mice. It also decreases expression of the inflammation-related genesIl2rgandXcr1in mouse spleen after 90 minutes when administered at a dose of 100 μg/kg.
SELANK Synthetic is a single, non-glycosylated polypeptide chain containing 7 amino acids, having a molecular mass of 751.89 Dalton and a Molecular formula of C33H57N11O9.
