Physical Properties
TB-500 corresponds to the LKKTETQ actin-binding fragment of Thymosin β4. This short, N-acetylated sequence is the region associated with G-actin binding and is studied for its solubility and stability under research conditions.
Analysis & Documentation
Identity
Each production lot is checked against the reference structure recorded for this compound:
- Classification — Synthetic N-acetylated heptapeptide
- Molecular formula — C₃₈H₆₈N₁₀O₁₄
- Expected mass — 889.02 Da
- CAS registry — 885340-08-9
- Chain length — 7 amino acids (acetylated)
- PubChem CID — 62707662
Analytical Methods
Testing is carried out per lot by an independent laboratory. The methods measure what the material is and how much of it is the target compound:
- RP-HPLC — reverse-phase separation of the target from process-related impurities; purity is reported as area percent of the main peak
- Mass spectrometry — observed mass compared against the expected molecular mass above
- Retention time — compared against a reference standard run under the same conditions
- Chromatogram — reproduced on the certificate so the peak and any shoulders can be inspected directly
Material & Documentation
What arrives, and how to tie it back to its paperwork:
- Appearance as supplied — Solid oral capsule (research-grade TB-500)
- Lot number — printed on the container label and used to look up the certificate
- Certificate — indexed by lot at Certificates of Analysis
Storage & Handling Guidelines
Capsule Storage
- Store in a cool, dry place at room temperature (15–25°C)
- Keep in the original sealed container, away from light and moisture
- Retain any desiccant packet included in the bottle
- Keep the container tightly closed between uses
Handling Guidelines
- No reconstitution, solvents, or mixing required
- Handle capsules with clean, dry hands
