TB-500 (Thymosin Beta-4 Fragment)

Axon Biolabs offers certified TB-500 synthetic peptide reference standards engineered for high precision in laboratory environments. Derived as an active region of the naturally occurring protein Thymosin Beta-4, this peptide sequence supports rigorous chemical testing. Furthermore, our laboratory produces this short synthetic sequence using automated liquid and solid-phase synthesis techniques to eliminate truncated impurities.

Researchers investigating actin-binding proteins, cell motility, and cytoskeletal reorganization frequently utilize this TB-500 synthetic peptide. Specifically, studies focus on how the peptide interacts with actin filaments during cellular movement. Additionally, for experimental protocols requiring dual-agent analytical matrices, researchers can review our pre-formulated BPC-157 TB-500 dual blend. As a result, laboratories can easily simplify complex sample preparation workflows.

Chemical Characterization

• Systematic Name: N-Acetyl-L-seryl-L-aspartyl-L-lysyl-L-prolyl-D-alanyl-L-glutamyl-L-lysine

• CAS Registry Number: 77591-33-4

• Molecular Formula: C38H68N10O14

• Molecular Mass: 889.01 g/mol

• Form: Lyophilized powder in glass vial

Handling & Storage Parameters

Store the vial in a desiccated environment at -20°C to maintain long-term peptide bond integrity. Furthermore, allow the vial to reach ambient room temperature before opening. This step prevents atmospheric condensation from contaminating the dry compound. However, personnel must reconstitute the powder using appropriate laboratory reagents immediately prior to testing.

Verification & Documentation

Axon Biolabs subjects every production lot to rigorous quality control protocols. Specifically, batch-specific HPLC chromatograms and mass spectrometry readings confirm molecular weight accuracy. Therefore, researchers can cross-reference compound entries on the NCBI PubChem Database. Furthermore, full test documents remain fully accessible via our Quality & COA Portal.
