Factory direct sales high quality large quantity supply of IGF-1LR3 raw material 946870-92-4 1g/raw material Pharmaceutical Grade

Product Overview

IGF-1 LR3 is a long-chain modified artificially synthesized polypeptide compound with fixed CAS registration number: 946870-92-4. It is produced by standard solid-phase peptide synthesis technology, then purified via multi-gradient reversed-phase high-performance liquid chromatography, and finally processed into finished lyophilized powder through vacuum freeze-drying technology. All synthesis, purification, filling and sealing operations are completed inside closed dust-free purification workshops. Each batch of finished products will undergo strict HPLC purity testing, impurity content inspection, microbial limit test and comprehensive appearance inspection before delivery to guarantee stable batch-to-batch quality consistency.

Our IGF-1 LR3 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 application, 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 meet 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. 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 technology effectively slows down hydrolysis and breakage of polypeptide molecular chains. Under sealed low-temperature storage conditions, the shelf life can reach 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. Great Water Solubility The lyophilized powder can be rapidly and completely dissolved in sterile purified water, PBS buffer solution and all common laboratory aqueous solvent systems. No insoluble precipitates or suspended residues will be produced 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 diverse biochemical reaction tests.
3. Ultra-Low Impurity Content 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 interfere with observation of cell physiological state, intracellular signal pathway research and protein binding experiment results, greatly reducing the probability of experimental errors.
4. Flexible Custom Packaging We support customized filling specifications for academic trial research. Large-capacity bulk drum packaging is also available for customers with long-term mass experimental needs. Each vial is tightly sealed with butyl rubber stopper and aluminum flip cap to ensure excellent air tightness.

Standard Storage Instructions

1. Short-term 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 storage (more than 3 months) Seal the bottle mouth for the second time, store the whole product at a constant low temperature of -20°C. Repeated freezing and thawing 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 The prepared aqueous experimental solution must be fully used up within 7 days under 2°C ~ 8°C refrigeration. Residual waste liquid shall be discarded in accordance with laboratory biochemical waste disposal norms to prevent microbial reproduction and solution deterioration.
