Research Grade ARA-290 Synthetic Peptide Raw Powder CAS 1208243-50-8 Lab Epidermal Molecular Study

Product Overview

ARA-290, CAS No. 1208243-50-8, is a synthetic polypeptide compound prepared via standardized solid-phase peptide synthesis routes. The raw material is purified by multi-gradient reversed-phase high performance liquid chromatography to obtain uniform white lyophilized powder. All synthesis, purification, split filling and sealing processes are completed in dust-free closed production workshops. Each batch undergoes strict HPLC purity detection, residual impurity analysis, microbial limit test and comprehensive appearance screening before delivery, ensuring consistent batch quality and repeatable experimental data.

This ARA-290 lyophilized powder is only supplied as biochemical intermediate raw material for in-vitro academic laboratory scientific research exclusively. It is strictly limited to basic cell biological experiments and intracellular epidermal signal pathway research in universities and biomedical research institutions. Any application related to human skin care, anti-wrinkle cosmetic raw materials, epidermal repair agents, topical preparations and human external use is completely prohibited. All production and packaging specifications are customized to meet laboratory research demands for life science epidermal cell molecular mechanism analysis.

The finished product presents fine white lyophilized powder with uniform texture, no caking, no color deviation and no visible foreign particles. The HPLC purity is steadily maintained at 99%. Trace unreacted amino acid raw materials, inorganic salts and synthetic byproducts are controlled at ultra-low levels, which will not bring extra interference to in-vitro keratinocyte cell model research, intracellular mitochondrial energy metabolism correlation experiments and epidermal molecular signal transduction detection, guaranteeing accurate and stable experimental test results.

Core Product Advantages

1. Excellent Physicochemical Stability The polypeptide mixture structure features high structural stability and strong anti-degradation performance under sealed low-temperature storage. The valid experimental storage period can reach 24 months. Aluminum cap sealed vial packaging effectively isolates moisture, oxidation and ultraviolet damage during long-distance cross-border transportation, maintaining stable physical and chemical properties for laboratory test use.
2. Outstanding Aqueous Solubility The lyophilized polypeptide raw material dissolves rapidly and completely in conventional laboratory aqueous solvents including purified water and PBS buffer. No insoluble particles, precipitation or suspended residues exist after dissolution. Researchers can prepare multiple concentration gradients flexibly according to different experimental protocols, suitable for cell incubation, liquid chromatographic detection and various biochemical reaction tests.
3. Ultra-Low Interference Impurities Multi-stage gradient HPLC purification thoroughly removes synthetic byproducts, residual raw materials and inorganic impurities. The ultra-low impurity content eliminates negative interference on cell morphology observation, intracellular epidermal metabolic pathway exploration and biochemical reaction verification, significantly reducing experimental error values and improving data repeatability.
4. Flexible Customized Packaging Specifications We provide diversified customized packaging for laboratory trial tests and long-term batch research experiments. All storage vials are sealed with professional butyl rubber stoppers and aluminum flip caps to achieve excellent airtightness and prevent sample deterioration. Customized bulk packaging service is available for institutional research laboratories.

Standard Storage Instructions

1. Short-term Temporary Storage (Within 3 Months) Keep the reagent vial tightly sealed, store in a cool dry environment away from strong light, and preserve under 2°C~8°C refrigeration condition. Reduce frequent opening operations to avoid moisture absorption and polypeptide structural degradation.
2. Long-term Storage (More Than 3 Months) Complete secondary sealing for the container and store stably at -20°C constant low temperature. Repeated freezing and thawing must be avoided to prevent molecular structural changes and attenuation of experimental biological activity.
3. Post-dissolution Storage Rules The prepared aqueous experimental solution must be fully used within 7 days under 2°C~8°C refrigeration. Waste liquid shall be disposed of in accordance with laboratory biochemical waste management standards to avoid solution deterioration and microbial contamination.
