TB-500 is a synthetic seven-residue research peptide commonly represented as an N-acetylated fragment associated with the 17-23 region of Thymosin Beta-4.
Its defined sequence includes N-terminal acetylation, which forms part of the complete molecular identity and should be retained in sequence and analytical documentation.
Commercial naming around TB-500 and full-length Thymosin Beta-4 can be inconsistent, so the applicable Certificate of Analysis should be treated as the controlling source for exact identity.
Research Applications
TB-500 may be examined in controlled non-clinical research involving:
- Peptide identity and characterization
- Molecular interaction studies
- Structure-function analysis
- Analytical peptide comparison
- Terminal-modification studies
- Stability assessment
- Non-clinical biochemical and cellular models
Experimental findings should remain specific to the applicable research system and should not be interpreted as evidence of recovery-related, regenerative, performance-related, therapeutic, or clinical effectiveness.
Structural Information
TB-500 is commonly represented as:
Ac-Leu-Lys-Lys-Thr-Glu-Thr-Gln-OH
One-letter representation:
Ac-LKKTETQ-OH
Key structural characteristics include:
- Seven amino-acid residues
- N-terminal acetylation
- Free C-terminal carboxyl group
Analytical Identification
Relevant analytical characterization may include:
- Amino-acid sequence confirmation
- N-terminal acetylation verification
- Molecular mass assessment
- Chromatographic purity testing
- Peptide identity verification
- Structural characterization
- Lot-specific quality analysis
If the supplied material is present as an acetate, TFA, or another counter-ion form, final molecular specifications should be matched to that exact preparation.
Specifications & Documentation
Lot-specific documentation should be reviewed for:
- Compound identity
- Amino-acid sequence
- Terminal modification
- Molecular formula
- Molecular weight
- Salt or counter-ion form
- Purity specification
- Analytical testing
- Lot or batch information
- Certificate of Analysis
- Storage requirements
Authenticated product-specific documentation should take precedence over generalized reference values.
Storage & Handling
Store according to the conditions specified on the product label and Certificate of Analysis. Protect the material from environmental conditions that could compromise peptide integrity.
Handling should follow established laboratory procedures appropriate for research materials.
