Thymosin B4 Acetate (TB500) Synthetic Polypeptide Raw Material 99% Purity 5mg/Vial US Warehouse Available For Laboratory Research

.

Product Overview

Thymosin B4 Acetate, abbreviated as TB500, is a synthetic linear polypeptide compound with the fixed CAS registration number 77591-33-4. It is synthesized by standard solid-phase peptide synthesis technology, then subjected to multi-gradient reversed-phase high-performance liquid chromatographic purification, and finally processed into finished lyophilized powder via vacuum freeze-drying technology. All synthesis, purification, filling and sealing procedures are completed in closed dust-free purification workshops. Each batch of finished goods will undergo strict HPLC purity testing, impurity content inspection, microbial limit test and comprehensive appearance inspection before delivery to ensure stable batch-to-batch quality consistency.

Our TB500 lyophilized powder is exclusively supplied as biochemical intermediate raw material for in-vitro academic laboratory scientific research purposes only. This product is strictly prohibited from being 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 needs of university life science laboratories, biomedical research institutes and biochemical R&D enterprises worldwide.

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 to cell experiments, intracellular metabolic pathway exploration and molecular mechanism research, ensuring high accuracy and excellent repeatability of experimental data.

Core Product Advantages

1. Stable Physicochemical Properties Vacuum freeze-drying molding technology effectively slows down the hydrolysis fracture 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, oxygen oxidation and ultraviolet damage during long-distance international cross-border transportation, and the intrinsic physicochemical properties of the product will not deteriorate under conventional transportation environments.
2. Excellent 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 exist 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 detection and multiple biochemical reaction tests.
3. Ultra-Low Impurity Interference 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 affect the observation of cell physiological state, intracellular signal pathway research and protein binding experiment results, greatly reducing the probability of experimental errors.
4. Customizable Packaging Specifications We adopt the standard filling specification of 5mg per vial for conventional laboratory trial research. 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 crimp cap to guarantee outstanding air tightness.

Standard Storage Regulations

1. Short-Term Temporary Storage (Within 3 Months) Tighten the bottle cap to realize complete airtight sealing, store in a cool and dry place away from direct sunlight, and place 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 Dissolving Into Aqueous Solution The prepared aqueous experimental solution must be fully consumed within 7 days under 2°C ~ 8°C refrigeration environment. The residual waste liquid shall be discarded in accordance with laboratory biochemical waste disposal specifications to prevent microbial reproduction and solution deterioration.
