Thymulin is a zinc-binding thymic nonapeptide supplied as a lyophilized powder for laboratory research. Its sequence is Pyr-Ala-Lys-Ser-Gln-Gly-Gly-Ser-Asn (9 residues). Researchers study it in T-cell differentiation models, where short peptides are used as tools for examining sequence-specific binding and protein interactions. Kimera Chems supplies this material for controlled laboratory studies only.
Chemical Composition & Purity
Thymulin has the molecular formula C₃₃H₅₄N₁₂O₁₅ and a molecular weight of 858.86 g/mol. It appears as a white to off-white lyophilized powder. Purity for this lot is documented on its batch-specific Certificate of Analysis, available for batch KC-TYL-BLU1.
The certificates for batch KC-TYL-BLU1 are labelled Thymalin. That label is incorrect: mass spectrometry identifies this batch as Thymulin, which is the name it is sold under. This applies to batch KC-TYL-BLU1 only, until this stock is gone.
Research Applications
Thymulin is used as a reference peptide in cell-free and in vitro systems. Its 9-residue sequence gives a defined three-dimensional shape, and the side chain charges determine how it behaves in binding studies.
- Receptor Binding: Measuring peptide-protein affinity in cell-free systems.
- Competitive Assays: Examining displacement of labeled ligands.
- Structural Studies: Analyzing folding patterns in solution.
- Stability Testing: Monitoring degradation under various conditions.
Storage & Handling Protocol
Store at controlled room temperature, sealed and protected from light.
Storage guidance is a house recommendation. Analytical documentation is per-lot release testing.
