Factory Supply Synthetic Polypeptide Raw Materials: Semax, MOTS-C, Selank Amidate, Oxytocin, BPC Custom Vial Specifications For Lab Research Only

Product OverviewOxytocin is a cyclic polypeptide compound with confirmed CAS number 16227580-64-6. It is synthesized by standard solid-phase peptide synthesis technology, then purified via multi-gradient reversed-phase high-performance liquid chromatography, and finally processed into finished lyophilized powder through vacuum freeze-drying technology. All synthesis, purification and filling procedures are carried out in closed dust-free purification workshops. Every batch of finished products will undergo strict HPLC purity detection, impurity content inspection, microbial limit test and appearance inspection before delivery to guarantee stable batch quality.

Our oxytocin lyophilized powder is exclusively provided as biochemical intermediate raw material for in-vitro academic laboratory scientific research only. This product is strictly prohibited from being used for human body injection, oral intake, skin external application, cosmetic raw material addition, clinical medication, health care product preparation and all other human-related consumption scenarios. All product design, production and packaging are customized to meet the experimental needs of university life science laboratories, biomedical research institutes and biochemical R&D enterprises.

The finished product presents uniform white lyophilized powder, with fine texture, no agglomeration, no color difference and no visible foreign impurities. The HPLC purity is stably controlled at 99%. The content of truncated peptide fragments, residual synthetic amino acid raw materials and inorganic salt impurities is extremely low, which will not bring extra interference variables to cell experiments, intracellular metabolic pathway exploration and molecular mechanism research, ensuring high accuracy and repeatability of experimental data.

 Core Product Advantages

1. Stable Physicochemical Properties Vacuum freeze-drying molding technology effectively slows down the hydrolysis fracture of polypeptide molecular chains. Under sealed low-temperature storage conditions, the shelf life can reach up to 24 months. Sealed aluminum cap packaging can resist moisture erosion, oxygen oxidation and ultraviolet damage during long-distance international cross-border transportation, and the product properties will not deteriorate under conventional transportation environments.
2. Excellent Water Solubility The lyophilized powder can be completely dissolved rapidly in sterile purified water, PBS buffer solution and all conventional laboratory aqueous solvent systems. No insoluble precipitates or suspended residues exist after dissolution. Researchers can prepare experimental solutions with different concentration gradients freely according to various experimental schemes, which is convenient for cell incubation, liquid phase detection and multiple biochemical reaction tests.
3. Ultra-Low Impurity Interference Multi-stage gradient chromatographic purification thoroughly removes incomplete synthetic peptide segments, residual raw materials and inorganic salts. The total impurity content is controlled at a very low level, which will not affect the observation of cell physiological state, intracellular signal pathway research and protein binding experiment results, greatly reducing the probability of experimental errors.
4. Standardized Customizable Packaging We adopt 10mg per vial standard filling specification for conventional laboratory trial research. Large-capacity bulk drum packaging can also be customized according to customers’ long-term large-batch experimental demands. Each vial is sealed with butyl rubber stopper and aluminum crimp cap to ensure excellent air tightness.

4. Standard Storage Regulations

1. Short-Term Storage (Within 3 Months) Tighten the bottle cap for complete airtight sealing, store in a cool and dry place away from direct sunlight, and place in a refrigerator at 2°C ~ 8°C. Do not open the cap frequently to avoid moisture absorption and air contact leading to molecular chain degradation.
2. Long-Term Preservation (More Than 3 Months) Carry out secondary sealing treatment on the bottle mouth, store the whole product at a constant low temperature of -20°C. Repeated freezing and thawing cycles are strictly forbidden, otherwise the spatial conformation of polypeptide will be destroyed, resulting in decreased biological activity and poor experimental applicability.
3. Storage Requirements After Dissolving Into Aqueous Solution The prepared aqueous experimental solution must be fully consumed within 7 days under 2°C ~ 8°C refrigeration environment. The residual waste liquid shall be discarded in accordance with laboratory biochemical waste disposal specifications to prevent microbial reproduction and solution deterioration.

5. Approved Application Range
