Lab Research Grade Thymalin Peptide Biochemical Intermediate Custom Vial Specifications

Product Overview

Thymalin is a synthetic polypeptide with fixed CAS registry number 79621-14-0. It is manufactured via standard solid-phase peptide synthesis technology, purified by multi-gradient reversed-phase high-performance liquid chromatography, and processed into lyophilized powder through vacuum freeze-drying process. All synthesis, purification, filling and sealing operations are completed in closed dust-free purification workshops. Every batch of finished products will pass strict HPLC purity detection, impurity analysis, microbial limit test and comprehensive appearance inspection before delivery to guarantee stable batch-to-batch quality consistency.

Our Thymalin lyophilized powder is exclusively supplied as biochemical intermediate raw material for in-vitro academic laboratory scientific research only. 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 experimental demands of university life science laboratories, biomedical research institutions and biochemical R&D enterprises worldwide.

The finished product is uniform white lyophilized powder with delicate 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 effectively slows down hydrolysis and chain breakage of polypeptide molecular chains. Under sealed low-temperature storage, the shelf life can reach 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 transport 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 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.
