    Peptide Supply & Product Introduction

    We specialize in the manufacture and supply of research-grade synthetic peptide raw materials for life science laboratories worldwide. Backed by mature supply chains, we have earned wide recognition from international partners. Our experienced team offers professional product matching and cross-border support. Custom packaging and specifications are available to meet personalized requirements. Our business covers numerous countries and regions, supporting both trial orders and long-term bulk cooperation.

    Customer needs always come first. We keep track of market updates and client feedback to continuously optimize our services. Standardized order management tracks every procedure to guarantee smooth order processing and on-time delivery.

    Company Profile

    Our company focuses on the R&D, production and supply of synthetic peptide raw materials for laboratory research. We have built complete standardized production workflows, supported by an experienced sales and technical team. We can deliver tailored raw material solutions according to your experimental protocols.

    Guided by integrity and quality-first principles, we keep close attention to trends in research materials and adjust our supply arrangements accordingly. From consultation and order confirmation to production scheduling and shipment, we make every effort to process your orders efficiently.

    Product Details

    This product series is research-grade synthetic peptide lyophilized powder, produced by chemical synthesis and professional lyophilization. Lyophilization lowers moisture content, slows molecular degradation and keeps good stability.

    Random sampling and testing are carried out for every batch before dispatch, with purity up to 99%. The powder is fine and uniform, dissolves readily in compatible solvents with low impurities. Batch-to-batch consistency is well controlled, making it a dependable raw material for biochemical tests, in vitro assays and academic research.

    We welcome small trial orders as well as bulk purchases. Better unit prices are available for larger volumes. Custom packaging options can also be discussed to fit different laboratory habits.

    Quality Assurance

    We implement strict end-to-end quality control covering raw material intake to finished goods release. All raw materials are sourced from qualified suppliers and inspected before warehousing.

    Production follows standard operating procedures. After synthesis and purification, finished products go through multiple tests. Goods can only leave the warehouse after passing all checks. Full batch records are retained, and relevant test information can be provided to support your research documentation when needed.

    Packaging & Logistics

    Packaging and Logistics

    The inner packaging is made of light-proof sealed bottles, and external materials are used to provide cushioning to minimize damage caused by collisions and temperature changes during transportation.

    We collaborate with reputable international logistics companies. After payment confirmation, the shipment is arranged, and a tracking number is provided so that you can check the status of the package at any time.

    Support Services

    Our sales and technical teams serve laboratory customers and reply to inquiries within 24 business hours. Feel free to reach out for advice on specification selection, storage guidance, order status or packaging requests. Custom labeling and repackaging solutions are available subject to feasibility.

    We will keep an eye on logistics after shipment. Please contact us immediately if any problem occurs on receipt, and we will work out a proper solution.

    Peptide Storage Instructions

    To maintain peptide stability, please observe the following rules:

    • Preserve peptides under cool, dry, dark and low-temperature conditions

    • Refrain from frequent freezing and thawing

    • Reduce exposure to ambient air

    • Protect peptides from light

    • Long-term storage of peptides in solution is not recommended

    • Prepare separate aliquots matching your experiment demands to prevent activity loss

    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.
