Description
TB-500 is a commercial research designation commonly associated with an N-acetylated seven-residue fragment related to Thymosin Beta-4. It is supplied for controlled laboratory, analytical, and scientific research.
The commonly referenced research identity is represented as Ac-LKKTETQ-OH. N-terminal acetylation forms part of the peptide's complete molecular identity and should be retained in technical and analytical documentation.
Commercial use of the term TB-500 is not completely standardized, and some suppliers may use the designation differently. For this reason, exact sequence, terminal state, molecular specifications, and counter-ion form should be confirmed using the applicable Certificate of Analysis.
Research Applications
TB-500 may be examined in controlled non-clinical research involving:
Peptide-fragment characterization
Sequence verification
Molecular interaction studies
Structure-function analysis
Terminal-modification characterization
Comparative peptide analysis
Chromatographic characterization
Stability assessment
Experimental observations should remain specific to the applicable research system and should not be interpreted as evidence of healing, recovery, regenerative, performance-related, therapeutic, or clinical effectiveness.
Structural Information
The commonly referenced TB-500 research peptide is:
Ac-Leu-Lys-Lys-Thr-Glu-Thr-Gln
One-letter representation:
Ac-LKKTETQ-OH
Key structural characteristics include:
Seven amino-acid residues
N-terminal acetylation
Linear peptide architecture
Free C-terminal carboxyl group in the referenced parent form
TB-500 should not automatically be treated as synonymous with full-length Thymosin Beta-4, which is a substantially larger peptide with a different molecular identity.
Analytical Identification
Relevant analytical characterization may include:
Amino-acid sequence confirmation
Molecular-mass assessment
N-terminal acetylation verification
Chromatographic purity testing
Peptide identity verification
Terminal-state confirmation
Counter-ion assessment
Lot-specific quality analysis
Specifications & Documentation
Lot-specific documentation should be reviewed for:
TB-500 identity
Confirmation of peptide fragment
CAS reference
Amino-acid sequence
Molecular formula
Molecular weight
N-terminal modification
C-terminal state
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 TB-500 naming conventions.
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 modified research peptide materials.
Research Use Only
TB-500 is supplied exclusively for laboratory research, analytical testing, and scientific reference purposes.
