We’ve witnessed countless research projects delayed by inconsistent peptide purity—batch-to-batch variations exceeding 5% that render Western blot results unreliable, and suppliers unable to provide complete COA documentation for regulatory compliance. As a team with over a decade of peptide synthesis experience supporting 10,000+ laboratories across 50+ countries, we understand how critical reagent stability is to research reproducibility.
Our Selank 99% lyophilized powder addresses these challenges through advanced solid-phase synthesis and triple purification processes, ensuring impurity levels below 0.1% and minimal batch differences. Produced in GMP-certified facilities with annual output exceeding 100KG, this cosmetic peptide meets the rigorous standards required for consistent experimental design, whether you’re conducting receptor binding assays or cell culture studies.
Selank, a synthetic peptide derived from tuftsin, has been the subject of numerous studies exploring its interaction with neuroregulatory pathways in in vitro models. As a research tool, this cosmetic peptide is commonly utilized in investigations of neuropeptide signaling mechanisms, with applications in neuroscience and molecular biology research. All experiments must adhere to institutional guidelines for in vitro research use only.
The ≥99.0% HPLC purity of our Selank powder is critical for eliminating interference from synthetic byproducts in mass spectrometry analysis, ensuring accurate molecular weight confirmation. The lyophilized form enhances stability during long-term storage, reducing peptide degradation that could compromise assay results. Our strict endotoxin control (<0.1EU/μg) is essential for maintaining cell viability in primary culture models, while batch-specific COA documentation enables precise traceability for GLP-compliant studies. Each specification is engineered to minimize experimental variables.
Choosing substandard Selank peptides risks introducing confounding variables—impurities that bind nonspecifically to target receptors, inconsistent solubility leading to variable dosing, or degradation products altering experimental outcomes. Our ISO 9001 and GMP-certified manufacturing ensures every vial of Selank 99% lyophilized powder delivers the same high quality, supporting reliable data across experiments. This consistency translates to fewer failed assays, reduced research costs, and faster progression of your studies.
We validate every batch of Selank through comprehensive testing: HPLC for purity quantification, mass spectrometry for molecular identity confirmation, and NMR for structural verification. Each shipment includes a complete Certificate of Analysis with batch-specific data, and we provide full technical support for method optimization. Our 10-day delivery window ensures minimal project delays, while bulk order capabilities support long-term research programs. If any product fails to meet specifications, we offer unconditional replacement—no questions asked.
Every order includes a detailed Certificate of Analysis (COA) and Material Safety Data Sheet (MSDS). Specific batch records, including raw material溯源 and manufacturing parameters, are available upon request by providing your order number. HPLC chromatograms, mass spectrometry reports, and NMR spectra can be furnished for regulatory submissions or internal quality control reviews.
Initiate your order by specifying required quantity, purity confirmation needs, and target delivery date. We’ll provide a detailed quote within 24 hours, followed by sample shipment with complete testing documentation for your evaluation. Once specifications are confirmed, production is scheduled with full quality control monitoring, and your order is dispatched with tracked logistics. Every step is designed to minimize administrative burden and accelerate your research timeline.
Q: What is the shelf life of Selank lyophilized powder?
A: When stored at -20°C in unopened packaging, Selank maintains stability for 24 months from the manufacturing date. Once reconstituted, aliquots stored at -20°C remain stable for approximately 6 months.
Q: Is this product suitable for in vivo research?
A: No. This product is supplied FOR RESEARCH USE ONLY, specifically for in vitro laboratory applications. It is not intended for animal or human use.
Q: What documentation is provided with each order?
A: Every shipment includes a Certificate of Analysis (COA) with batch-specific HPLC, MS, and purity data, along with an MSDS. Additional documentation can be requested prior to purchase.
Can you accommodate custom synthesis requests?
A: Yes. Our facilities support custom peptide synthesis with modifications including N-terminal acetylation, C-terminal amidation, and isotopic labeling. Minimum custom order quantities apply.
How is purity verified?
A: Purity is confirmed using reverse-phase HPLC with UV detection at 220nm, against an external standard. We also perform mass spectrometry to confirm molecular weight and identity, with results provided in the COA.
