      Product Detail  


    Company Profile

    Our enterprise focuses on developing and supplying synthetic peptide raw materials for life science laboratory research. We have built standardized production workflows and assembled an experienced technical and sales team. We can tailor raw material solutions according to each lab’s experimental design, serving researchers across multiple regions worldwide.

    We uphold integrity and consistent product performance as our core principles. We keep track of evolving needs within the research community and adjust our inventory and supply plans accordingly. From initial consultation and order confirmation through production scheduling and dispatch, we aim to deliver streamlined service for every submission.

    Product Details

    This product line comprises research-grade synthetic peptide lyophilized powder, manufactured via chemical synthesis followed by freeze-drying processing. The lyophilization process lowers moisture levels, slows molecular degradation, and helps preserve material stability over storage.

    Each batch features fine, homogeneous powder that dissolves readily in compatible solvents, with low impurity profiles and consistent performance across production runs. It serves as a reliable material for biochemical assays, in vitro experiments and academic research projects.

    We support small trial batches as well as large-volume orders. Unit pricing becomes more competitive for larger quantities. Custom packaging arrangements can also be discussed to accommodate different laboratory operational preferences.

    Product Consistency

    We maintain careful oversight throughout the whole production workflow. Starting materials are sourced from qualified suppliers and reviewed before entering production.

    Synthesis and purification follow established operating procedures. Finished materials undergo multiple analytical assessments to confirm purity, moisture content and impurity profiles.

    Materials are cleared for dispatch once evaluation criteria are met. Batch records are retained, and relevant supporting documentation can be shared to support your research records upon request.

    Packaging and Logistics

    Our inner packaging uses professional light-blocking sealed vials. Outer packaging includes protective cushioning to reduce mechanical shock and temperature variation risks during transit.

    We work with trusted international logistics partners. Shipment will be arranged within 1–2 business days after payment confirmation, and a tracking number will be provided for shipment monitoring.

    Support Services

    Our sales and technical team provides dedicated support for laboratory buyers and responds to inquiries within 24 business hours.

    You may reach out for guidance on product selection, storage recommendations, order updates or packaging preferences. Custom labeling and repackaging options can be explored where feasible.

    After shipment, we continue tracking delivery progress. Please contact us promptly if any issues arise upon receipt, and we will work toward a suitable resolution.

    Storage Conditions

    Store in a cool, dry, dark, low-temperature environment. Avoid repeated freeze-thaw cycles. We recommend aliquoting materials based on experimental usage to help maintain sample integrity.

    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.
