Purity & Analytical Verification (HPLC & MS)

Every batch of TB-500 supplied by The Peptide Store is independently verified to a minimum purity of ≥98% using high-performance liquid chromatography (HPLC). Mass spectrometry (MS) confirmation is performed on each production lot to authenticate molecular weight and confirm sequence integrity. A full Certificate of Analysis (COA) is available for every order, providing researchers with the analytical documentation necessary for publication-grade experimental reporting and institutional compliance requirements.

Quality Control & Lyophilization Integrity

TB-500 is produced under strict quality control protocols that encompass raw material sourcing, synthesis, purification, and final formulation. The lyophilization process is conducted under controlled conditions to remove residual moisture while preserving peptide structure and biological activity in research settings. Vials are sealed under inert atmosphere to prevent oxidative degradation during storage and transit. Each lot undergoes multi-point QC testing before release, ensuring that researchers receive a product that meets the highest standards of laboratory-grade quality available on the market today.

Safety, Handling & Laboratory Precautions

TB-500 is a research-grade chemical compound intended exclusively for use by trained laboratory personnel in appropriately equipped research facilities. Standard laboratory safety practices must be observed at all times, including the use of personal protective equipment (PPE) such as gloves, eye protection, and lab coats. This compound must not be administered to humans or animals under any circumstances. Researchers should consult their institution’s chemical safety guidelines and applicable regulatory frameworks prior to handling. Dispose of unused material in accordance with local laboratory waste disposal regulations.

Reconstitution, Packaging & Storage

TB-500 is supplied as a lyophilized powder in a sterile, sealed research vial. Reconstitution should be performed according to validated institutional laboratory protocols using appropriate research-grade solvents as determined by the principal investigator. Store lyophilized peptide at −20°C in a dry, dark environment. Once reconstituted for research purposes, the solution should be aliquoted and stored according to established laboratory best practices to maintain integrity. The Peptide Store packages all peptide orders with care to ensure product stability throughout transit.
