Peptide Structure & Amino Acid Sequence

TB-500 is a 43-amino acid peptide with the following confirmed sequence:

Ac-Ser-Asp-Lys-Pro-Asp-Met-Ala-Glu-Ile-Glu-Lys-Phe-Asp-Lys-Ser-Lys-Leu-Lys-Lys-Thr-Glu-Thr-Gln-Glu-Lys-Asn-Pro-Leu-Pro-Ser-Lys-Glu-Thr-Ile-Glu-Gln-Glu-Lys-Gln-Ala-Gly-Glu-Ser-OH

The N-terminal acetylation and C-terminal free acid configuration are characteristic of the biologically relevant form of Thymosin Beta 4. This precise sequence is critical for researchers conducting studies on actin-binding domains, intracellular signaling cascades, and peptide-protein interaction models.

Chemical & Physical Characteristics

• Molecular Formula: C₂₁₂H₃₅₀N₅₆O₇₈S
• Molecular Weight: 4,963.44 g/mol
• Appearance: White to off-white lyophilized powder
• Solubility: Soluble in aqueous buffers; specific reconstitution conditions should be determined per research protocol
• Storage Stability: Stable under recommended cold-chain storage conditions

These physicochemical parameters are consistent with peer-reviewed reference standards for synthetic Thymosin Beta 4 analogs, making TB-500 from Revo Peptide a dependable reference compound for in vitro research applications.

Purity & Analytical Verification (HPLC & MS)

Every batch of TB-500 supplied by Revo Peptide undergoes rigorous dual-method analytical verification. Reverse-phase high-performance liquid chromatography (RP-HPLC) is employed to confirm peptide purity at ≥98%, with batch records indicating purity consistently exceeding 99%. Mass spectrometry (MS) analysis validates the molecular weight and confirms the correct amino acid composition and sequence integrity. Researchers can request batch-specific Certificates of Analysis (CoA) to support their documentation and reproducibility requirements.

Quality Control & Lyophilization Integrity

TB-500 is produced using solid-phase peptide synthesis (SPPS) under controlled manufacturing conditions. Following synthesis and purification, the peptide is lyophilized using pharmaceutical-grade freeze-drying processes to ensure long-term stability, moisture exclusion, and preservation of structural integrity. Each vial is sealed under inert atmosphere to prevent oxidative degradation. Revo Peptide’s quality control pipeline includes identity confirmation, endotoxin screening, and visual inspection prior to dispatch, ensuring that researchers receive product meeting the highest analytical standards available for research-grade peptides.

Safety, Handling & Laboratory Precautions

TB-500 is supplied exclusively as a research reagent and must be handled in accordance with standard laboratory safety protocols. Researchers should wear appropriate personal protective equipment (PPE), including gloves, lab coats, and eye protection, when handling lyophilized peptide material. This compound is not approved for any form of human or animal administration. All handling, storage, and disposal must comply with applicable institutional biosafety guidelines and local regulatory frameworks governing research chemicals.

Reconstitution, Packaging & Storage

• Packaging: Single-use amber glass vial, hermetically sealed
• Form: Lyophilized white powder, 2mg per vial
