Epithalon Polypeptide Lyophilized Powder 10mg Per Vial Only For Laboratory In Vitro Research

Product Overview

Epithalon is a kind of artificially synthesized short-chain linear polypeptide compound, with the confirmed CAS number 307297-39-8. It is manufactured through standardized solid-phase peptide synthesis technology, followed by multi-gradient reversed-phase chromatographic purification and vacuum freeze-drying molding technology. All production procedures are completed in closed dust-free workshops, and every batch of finished products will undergo strict HPLC purity testing, impurity inspection and microbial limit testing before delivery.

Our Epithalon lyophilized powder is exclusively supplied as biochemical raw material for in-vitro academic laboratory scientific research only. This product shall never be applied to human body injection, oral administration, skin external use, cosmetic raw material addition, clinical medication, health care product production and any other human-related consumption scenarios. All product design, production and packaging are oriented to meet the experimental demands of life science laboratories, biomedical research institutions and university biochemical research groups.

The finished product presents uniform white lyophilized powder, with fine texture, no caking, no color difference and no visible foreign impurities inside. The HPLC purity is stably controlled at 99%, low content of truncated peptide fragments, synthetic residual raw materials and inorganic salt impurities, which can effectively avoid extra interference factors during cell experiments, biochemical pathway exploration and molecular mechanism research, ensuring high accuracy and repeatability of experimental data.## Core Product Characteristics

1. Excellent Physicochemical Stability Vacuum freeze-drying molding technology greatly slows down the hydrolysis fracture rate of polypeptide molecular chains. Under sealed low-temperature storage conditions, the shelf life can reach up to 24 months. Sealed packaging can effectively resist moisture invasion, oxygen oxidation and ultraviolet ray damage during long-distance international cross-border transportation, so the product property will not deteriorate in conventional transportation environments.
2. Perfect Water Solubility Performance The lyophilized powder can be rapidly and completely dissolved in sterile purified water, PBS buffer solution and all conventional laboratory aqueous solvent systems, without insoluble precipitates or suspended residues after dissolution. Researchers can freely prepare experimental solutions with different concentration gradients according to specific experimental schemes, which is convenient for cell incubation, liquid-phase detection and various biochemical reaction tests.
3. Ultra-Low Impurity Interference Multi-stage gradient chromatographic purification thoroughly removes incomplete synthetic peptide segments, residual amino acid raw materials and inorganic salts. The total impurity content is controlled at an extremely low level, which will not affect intracellular signal pathway research, cell physiological state observation and protein binding experiment results, greatly reducing experimental error probability.
4. Diversified Customizable Packaging Specifications We provide two mainstream filling specifications: 10mg per vial for small trial experiments and 50mg per vial for long-term continuous research. Bulk drum packaging can also be customized according to customers’ large-batch experimental demands to meet different consumption demands of scientific research teams. Each vial is sealed with butyl rubber stopper and aluminum cap to guarantee tightness.

Standard Storage Specifications

1. Short-Term Temporary Storage (Within 3 Months) Tighten the bottle cap completely to finish airtight sealing, place the product in a dry and cool environment away from direct sunlight, and store it in a refrigerator at 2°C ~ 8°C. Do not open the bottle cap frequently to prevent moisture absorption and air contact from causing 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 prohibited, otherwise the spatial structure of the polypeptide will be destroyed, leading to the decline of biological activity and poor experimental applicability.
3. Preservation Requirements After Dissolving Into Aqueous Solution The prepared aqueous experimental solution must be used up completely within 7 days under 2°C ~ 8°C refrigerated environment. The remaining waste liquid shall be discarded in accordance with laboratory biochemical waste disposal norms to prevent microbial reproduction and solution deterioration.
