High Purity AHK-Cu Synthetic Copper Peptide Raw Material 99% Lyophilized Powder CAS 682809-81-0

Product Overview

AHK-Cu, a synthetic copper-binding short-chain polypeptide, has the fixed CAS registry number 682809-81-0. It is synthesized via standard solid-phase peptide synthesis technology, purified by multi-gradient reversed-phase high-performance liquid chromatography, and finally made into lyophilized powder through vacuum freeze-drying technology. All synthesis, purification, filling and sealing operations are carried out in closed dust-free purification workshops. Every batch of finished products undergoes strict HPLC purity testing, impurity detection, microbial limit test and comprehensive appearance inspection before delivery to guarantee stable batch-to-batch quality consistency.

Our AHK-Cu lyophilized powder is only supplied as biochemical intermediate raw material for in-vitro academic laboratory scientific research exclusively. This product is strictly prohibited for human injection, oral intake, topical skin application, cosmetic raw material blending, clinical medication, health care product preparation and all other human-related consumption scenarios. All product design, production and packaging schemes are customized to meet the experimental demands of university life science laboratories, biomedical research institutions and biochemical R&D enterprises worldwide.

The finished product is uniform blue 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 kept at an extremely low level, which will not bring extra interference variables in 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 and chain breakage 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, oxidative deterioration and ultraviolet radiation during long-distance international transportation, and the inherent physicochemical properties of the product will not deteriorate under conventional transportation environments.
2. Perfect Water Solubility 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 appear after dissolution. Researchers can freely prepare experimental solutions with different concentration gradients according to various experimental schemes, which is convenient for cell incubation, liquid-phase chromatographic detection and various biochemical reaction tests.
3. Ultra-Low Impurity Interference Multi-stage gradient chromatographic purification thoroughly removes incompletely synthesized peptide fragments, residual raw materials and inorganic salt impurities. The total impurity content is controlled at an extremely low level, which will not interfere with the observation of cell physiological state, intracellular signal pathway research and protein binding experiment results, greatly reducing the probability of experimental errors.
4. Flexible Customized Packaging Specifications We provide flexible customized filling specifications for academic research trials. 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 flip cap to ensure outstanding air tightness.

Standard Storage Instructions

1. Short-term Temporary Storage (Within 3 Months) Tighten the bottle cap for complete airtight sealing, store in a cool and dry place away from direct sunlight, and preserve 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 the polypeptide will be destroyed, resulting in decreased biological activity and poor applicability for subsequent experiments.
3. Storage Requirements After Dissolution Into Aqueous Solution The prepared aqueous experimental solution must be fully consumed within 7 days under refrigerated environment of 2°C ~ 8°C. Residual waste liquid shall be discarded in accordance with laboratory biochemical waste disposal specifications to prevent microbial reproduction and solution deterioration.
