Biochemical Intermediate FOXO4 Peptide Custom Vial Specifications For Cell Aging Mechanism Research

Product Overview

FOXO4-D-Retro is a synthetic polypeptide with unique CAS registration number 2460055-10-9. It is manufactured via standard solid-phase peptide synthesis process, purified with multi-gradient reversed-phase high performance liquid chromatography, and made into lyophilized powder by vacuum freeze-drying technology. All synthesis, purification, filling and sealing procedures are operated in closed dust-free purification workshops. Each batch of finished products undergoes strict HPLC purity testing, impurity detection, microbial limit inspection and comprehensive appearance screening before delivery to guarantee stable batch-to-batch quality consistency.

Our FOXO4-D-Retro 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 administration, topical skin coating, cosmetic raw material compounding, clinical medication, health care product production and all other human-related commercial application scenarios. All product design, production and packaging schemes are customized to meet experimental demands of university life science laboratories, biomedical research institutes and biochemical R&D enterprises worldwide.

The finished product is 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 amino acid raw materials and inorganic salt impurities is maintained at an extremely low level, which will not bring extra interference variables in cell senescence experiments, cell cycle regulatory 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 effectively slows down 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 flip cap packaging can resist moisture erosion, oxidative degradation and ultraviolet radiation during long-distance international transportation, and the inherent physicochemical properties of the product will not deteriorate under conventional transportation environments.
2. Outstanding Water Solubility The lyophilized powder can be quickly and completely dissolved in sterile purified water, PBS buffer and all conventional laboratory aqueous solvent systems. No insoluble precipitates or suspended residues occur after dissolution. Researchers can freely prepare experimental solutions with different concentration gradients according to various experimental protocols, which is suitable 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 ultra-low level, which will not interfere with cell physiological state observation, intracellular FOXO4 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 trial experiments. Large-volume bulk drum packaging can also be customized according to customers’ long-term mass experimental requirements. Each vial is tightly sealed with butyl rubber stopper and aluminum flip cap to guarantee excellent air tightness.

Standard Storage Instructions

1. Short-term Temporary Storage (Within 3 Months) Tighten the cap for full airtight sealing, store in a cool dry place away from direct sunlight, and preserve in a 2°C ~ 8°C refrigerator. Avoid frequent opening of the cap to prevent moisture absorption and air-induced molecular chain degradation.
2. Long-term Storage (More Than 3 Months) Perform secondary sealing treatment on the bottle mouth, and 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 Rules After Dissolving Into Aqueous Solution The prepared aqueous experimental solution must be fully used up within 7 days under 2°C ~ 8°C refrigeration. Residual waste liquid shall be disposed of in accordance with laboratory biochemical waste management standards to avoid microbial reproduction and solution deterioration.
