Research Grade Selank Neuroregulatory Peptide Reagent

Product Advantages

1. Stable Biological Activity for Neuroendocrine & Nervous System Research

   
   

   Selank acts as a classic reference peptide in neuroregulatory pharmacology research. It can participate in the regulation of neuropeptide expression, balance inflammatory cytokine secretion and modulate central nervous system physiological signal transduction. A large number of peer-reviewed academic papers take Selank as experimental material to carry out in-depth research on neuron homeostasis, cellular stress response and related hematological and immunological mechanisms. Lyophilized powder preparation effectively inhibits peptide hydrolysis, oxidation and chain breakage under conventional preservation environment, maintaining consistent and stable biological activity during long-term storage, repeated sampling and continuous cell incubation experiments. The stable molecular structure makes it suitable for long-cycle in vitro cell tests and multi-round pharmacodynamic verification.
2. Complete and Traceable Batch Quality Control System

   
   

   Every single production batch undergoes full-range multi-index quality inspection before delivery. Reverse-phase high-performance liquid chromatography (RP-HPLC) is adopted for quantitative purity analysis, and electrospray ionization mass spectrometry (ESI-MS) verifies molecular weight to confirm complete structural consistency. Standard Certificate of Analysis (COA) containing itemized comprehensive test records can be provided to customers upon formal request. All testing indicators including moisture content, residual organic solvents, single impurity distribution and bacterial endotoxin level fully comply with international general testing standards for cell-level laboratory peptide reagents. Each production batch retains independent sealed reserve samples for long-term traceability, supporting repeatable and reproducible scientific verification experiments for global research teams.
3. Excellent Aqueous Solubility Suitable for In Vitro Mammalian Cell Assays

   
   

   The lyophilized solid powder shows favorable solubility performance in sterile deionized water, PBS buffer and other conventional aqueous solutions widely used in primary neuron cell culture systems. The prepared stock solution can be further diluted according to diversified experimental concentration gradients for neuron activity detection, inflammatory factor expression analysis, intracellular signal pathway verification and multi-dimensional in vitro neuropharmacological functional evaluation. No highly toxic organic solvent is required for routine laboratory testing operations, which effectively reduces unnecessary chemical interference to cell microenvironment and improves the stability and repeatability of experimental data.
4. Sealed Vial Packaging & Flexible Customized Global Supply

   
   

   We adopt standard sealed vial packaging for all regular specifications. Customized net weight setting, external label content design and special shock-proof packaging schemes are supported to satisfy diversified personalized demands from different research project teams. Moisture-proof, shock-proof and light-proof outer packaging configuration guarantees safe long-distance cross-border transportation during international sea and air logistics. Flexible order quantity can meet the experimental demands of preliminary small-scale exploratory tests as well as large-scale continuous repeated verification research.

Storage, Transportation & Safety Operation Instructions

1. Storage Tips: Keep the reagent vial tightly sealed immediately after sampling. Avoid frequent repeated freezing and thawing cycles, which will accelerate peptide degradation and gradually reduce biological activity. It is strongly recommended to separate prepared stock solution into multiple small aliquots and store at -20℃. Isolated storage away from other biochemical reagents is recommended.
2. Transportation: Small orders adopt sealed moisture-proof packaging; cold-chain transportation can be chosen for bulk orders or transoceanic long-distance shipment.
3. Operation Guidelines: Operators must wear nitrile gloves, lab coat and safety goggles. Prevent aerosol inhalation and direct contact with skin and mucous membrane. In case of accidental contact, rinse with plenty of clean running water immediately.
4. Important Disclaimer: This product is FOR LABORATORY SCIENTIFIC RESEARCH ONLY. Any therapeutic application for human beings or experimental animals is strictly prohibited. All purchasers and users shall bear all corresponding liabilities for improper use beyond laboratory research scope.
