High Purity DAC Polypeptide Raw Material 10mg/Vial Custom Specifications For Laboratory In Vitro Research Only

Product Overview

DAC is a custom artificially synthesized short-chain polypeptide compound without unified public CAS registration number. It is produced adopting standard solid-phase peptide synthesis technology, followed by multi-gradient reversed-phase high-performance liquid chromatographic purification, and finally processed into finished lyophilized powder through vacuum freeze-drying technology. All synthesis, purification, filling and sealing procedures are finished inside closed dust-free purification workshops. Each batch of finished goods will undergo strict HPLC purity detection, impurity content inspection, microbial limit test and comprehensive appearance inspection before delivery to guarantee stable batch-to-batch quality consistency.

Our DAC lyophilized powder is exclusively supplied as biochemical intermediate raw material for in-vitro academic laboratory scientific research purposes only. This product is strictly forbidden to be applied to human body injection, oral intake, skin external use, cosmetic raw material addition, clinical medication, health care product preparation and all other human-related consumption scenarios. All product design, production and packaging schemes are customized to satisfy the experimental demands of life science laboratories, biomedical research institutes and biochemical R&D enterprises all over the world.

The finished product presents uniform white lyophilized powder, featuring fine texture, no agglomeration, no color difference and no visible foreign impurities inside. 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 kept at an extremely low level, which will not bring extra interference variables during cell experiments, intracellular metabolic pathway exploration and molecular mechanism research, ensuring high accuracy and excellent repeatability of experimental data.

Core Product Advantages

1. Excellent Physicochemical Stability 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 effectively resist moisture erosion, oxygen oxidation and ultraviolet damage during long-distance international cross-border transportation, and the inherent physical and chemical properties of the product will not deteriorate under conventional transportation environments.
2. Perfect Aqueous 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. No insoluble precipitates or suspended residues exist after dissolution. Researchers can freely prepare experimental solutions with different concentration gradients according to diverse experimental schemes, which is convenient for cell incubation, liquid-phase chromatographic detection and various types of biochemical reaction tests.
3. Ultra-Low Impurity Interference Multi-stage gradient chromatographic purification thoroughly removes incompletely synthesized peptide segments, residual raw materials and inorganic salt impurities. 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. Diversified Customizable Packaging Specifications We adopt the standard filling specification of 10mg per vial 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 tightly sealed with butyl rubber stopper and aluminum crimp cap to guarantee outstanding air tightness.

Standard Storage Regulations

1. Short-Term Temporary Storage (Within 3 Months) Tighten the bottle cap to realize complete 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 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 prohibited, otherwise the spatial conformation of the polypeptide will be destroyed, resulting in decreased biological activity and poor applicability for subsequent experiments.
3. Preservation Requirements After Dissolving Into Aqueous Solution The prepared aqueous experimental solution must be fully consumed within 7 days under 2°C ~ 8°C refrigerated environment. The residual waste liquid shall be discarded in accordance with laboratory biochemical waste disposal specifications to prevent microbial reproduction and solution deterioration.
