Research Grade Selank Peptide Lyophilized Powder For Laboratory Scientific Research Only

Selank belongs to synthetic heptapeptide compounds, presented as lyophilized powder for laboratory‑oriented scientific research only. The material shows fine white freeze‑dried solid status, uniform color distribution, loose texture without caking or discoloration. Adopting multi‑step solid‑phase peptide synthesis and high‑efficiency purification technology, the final product purity can reach ≥99% tested by HPLC, fully meeting strict requirements of biochemical laboratory analysis, compound study and related experimental projects.

Multiple specification options are available:5mg,10mg,20mg,30mg per glass vial. Diversified specifications can cover small‑scale sample trial experiments as well as large‑batch research project consumption demands. All manufacturing procedures are operated under standardized production control system, including raw‑material incoming inspection, peptide synthesis, chromatographic purification, sterile lyophilization process, vial filling and sealing. Every production batch undergoes complete internal quality inspection before ex‑warehouse. Supporting documents including Certificate of Analysis (COA), HPLC chromatogram, batch test record can be provided upon buyer’s request for laboratory file archiving.

Important Notice: This product is exclusively for scientific laboratory research. It is not suitable for human intake, clinical trial, medical diagnosis or treatment application.

Chemical stability of lyophilized peptide is highly sensitive to ambient conditions. For long‑term preservation, keep the vial tightly sealed and stored at -20℃, under dry, dark and low‑humidity surroundings. Prevent frequent temperature fluctuation and repeated freeze‑thaw operations, which may cause performance change of peptide substance. Avoid high‑temperature exposure and direct sunlight irradiation. Once the vial seal is opened, it is suggested to finish relevant laboratory tests in a short time and reduce long‑time exposure to air.

We support flexible order modes, covering small‑quantity sample orders and large‑volume bulk wholesale business. Adequate stock is maintained in warehouse, so goods can be packed and dispatched promptly once order is confirmed. Custom packaging service is acceptable according to customers’ special requirements. Each single vial is sealed with high‑quality rubber stopper and aluminum cap. Outer packing uses shock‑resistant foam, cushioning material and moisture‑proof bag, effectively lowering risks such as collision damage, damp contamination during long‑distance international logistics and cross‑border transportation.

Quality Control & Core Advantages

Superior purity: Advanced multi‑stage purification process controls impurity content at low level, HPLC testing ensures stable high purity for each batch.

Excellent batch‑to‑batch consistency: Strict process parameter locking during production. Index deviation among different batches is minimal, suitable for repeated contrast experiments and continuous research work.

Complete supporting documentation: Each batch matches corresponding COA, HPLC spectrum and inspection record, convenient for laboratory data filing.

Flexible procurement solution: Support small sample trial for preliminary experiment, also capable for large‑volume bulk supply for institutional research projects.

Fast order execution: Sufficient spot inventory, standardized packing flow, shorten preparation cycle before shipment.

Reliable protective packaging: Multi‑layer shockproof and moisture‑proof packing design, reduce loss caused by rough handling in international delivery.

Professional technical support: Our team has rich experience in peptide raw‑material supply. If you have inquiries related to product preservation, dissolution operation, batch information and ordering arrangement, please do not hesitate to contact us, we will respond and offer practical support in timely manner.

We have established a complete raw‑material traceability system. The whole process from upstream raw‑material procurement to finished‑product delivery can be traced. Inspection nodes are set for each procedure to avoid quality risks caused by raw‑material mixing and process deviation. All peptide products are controlled in accordance with laboratory‑grade standards, not processed for pharmaceutical use, and supplied only for research institutions and laboratory‑related customers. After placing an order, we will re‑check goods, verify specifications, batch information and packaging condition, to ensure delivered products are consistent with test report data. For bulk buyers, batch pre‑confirmation service is available. Relevant batch documents can be offered before shipment to support customers’ internal project review.

Upon receiving goods, please inspect outer package and vial condition immediately. Please contact us timely if you find breakage or powder leakage. After receipt, transfer goods to -20℃ storage environment as soon as possible, avoid long‑term placement under room temperature. Lyophilized peptide is sensitive to ambient temperature and humidity. Operators are suggested to open vials and perform dissolution under dry and clean laboratory conditions to reduce contamination risk from external impurities. If you need reference about dissolution ratio, experimental operation or sample shelf‑life, feel free to reach us for technical suggestions.
