A full Certificate of Analysis (COA) is provided with every order for full traceability.
Optimal Stability & Solubility: Supplied as a white to off-white lyophilized powder, our TB500 offers excellent long-term stability when stored at -20°C in a dry, dark environment, with a 2-year shelf life for unopened products. It demonstrates superior solubility in aqueous solutions (sterile water, PBS, physiological saline), enabling easy, consistent preparation for a wide range of laboratory protocols without compromising experimental integrity.
Advanced Manufacturing & Batch Consistency: We utilize cutting-edge solid-phase peptide synthesis technology to produce TB500, ensuring precise molecular structure and exceptional batch-to-batch consistency. This advanced manufacturing process eliminates impurities and preserves the peptide’s native biological activity, making our product the ideal choice for long-term, large-scale research projects.
Versatile Research Compatibility: Our TB500 is formulated to support diverse preclinical research applications, catering to the needs of academic laboratories, biotech firms, and research institutions worldwide. Its high purity and consistent activity make it suitable for in vitro experiments, cell culture studies, and preclinical research models.
GMP-Aligned Manufacturing & Compliance: All production processes follow strict GMP-aligned quality management systems, from raw material sourcing to final packaging. We adhere to international laboratory reagent standards, ensuring our TB500 meets the rigorous requirements of scientific research.

Storage & Handling Guidelines

Store the lyophilized powder at -20°C in a dry, dark environment to preserve optimal stability.
Once reconstituted, the solution should be stored at 4°C and used within 7 days, or aliquoted and frozen at -20°C for long-term storage to avoid repeated freeze-thaw cycles.
Protect from direct sunlight, high temperature, and moisture to prevent product degradation.
