Thymosin Beta 4 is a synthetic peptide compound produced for research applications. This peptide consists of forty-three amino acids linked in a specific sequence. An actin-binding peptide is a molecular structure that interacts with actin proteins in experimental models. Actin is a protein found in cells that scientists study in laboratory settings. This peptide’s structure allows it to bind with actin in experimental test systems. This synthetic peptide origin ensures batch-to-batch consistency for research protocols. The compound represents a defined amino acid sequence for cellular research investigation. Researchers examine this peptide’s properties within controlled laboratory conditions without therapeutic context.

Identity confirmed

LC-MS confirms the molecule in the vial is TB-500 (Thymosin Beta 4).

Purity measured

The same LC-MS run measures the share that is the target peptide.

Lot-linked report

Each report names the lot it was run on.

Each lab report is tied to its lot.

Reports are issued by independent labs and name the lot they were run on.

The steps behind each certificate.

See how we test
Step 1

Synthesis and lyophilization

Synthesized and freeze-dried in US facilities, then given a lot number.

Step 2

Samples go to third-party labs

Finished vials from the lot are sent to independent labs.

Step 3

LC-MS: identity, purity, net content

One run confirms the molecule and measures its purity.

Step 4

LAL endotoxin screen

Bacterial endotoxin is checked against a 0.5 EU/mL limit.
