TB-500
TB-500 is commonly described in analytical literature as a synthetic N-acetylated peptide fragment related to the actin-binding region of thymosin beta-4. Direct evidence for TB-500 itself is limited and should not be conflated with research on the full endogenous protein.
Thymosin beta-4 is a naturally occurring actin-sequestering protein, while TB-500 has been identified as a shorter synthetic peptide associated with the LKKTETQ region. These materials are not interchangeable in sequence, structure, or evidence base.
Research on thymosin beta-4 and related fragments examines actin dynamics, cell migration, angiogenic signaling, extracellular-matrix responses, and tissue-repair models. Whether a specific fragment reproduces the full protein’s activity depends on the model and formulation.
Relevant work includes peptide identification by mass spectrometry, fragment stability, actin-binding assays, endothelial and keratinocyte models, comparative studies with full-length thymosin beta-4, and anti-doping analytical methods.
Much of the biological literature concerns full-length thymosin beta-4, animal models, or veterinary/analytical detection. High-quality human evidence for commercial TB-500 claims is lacking, so recovery or performance claims are not scientifically justified.
Confirm the exact sequence and form stated in the batch documentation. Record N-terminal modification, vial amount, lot, solvent, concentration, storage, and assay controls. Do not label a fragment as full-length thymosin beta-4.
The label, lot number, declared vial amount, and batch-specific documentation are the authoritative references for the supplied material. Any certificate should be matched to the lot number on the vial. A purity result describes analytical composition; it does not establish sterility, clinical safety, or suitability for human use.
Published research about the molecule TB-500 describes specific experimental materials, formulations, doses, populations, and controlled conditions. Those findings cannot be transferred automatically to this Peptara Lab research material and are not a promise of clinical effect.
TB-500 is supplied exclusively for controlled laboratory and in vitro research. The experimental design, solvent, concentration, and handling procedure must be determined by qualified personnel under an approved institutional protocol.
Record the product title, lot number, vial amount, receipt date, opening date, storage conditions, operator, and experimental use in the laboratory log.
Confirm solvent and container compatibility, use appropriate blanks and reference standards, and document any deviation from the approved method.
Orders are prepared on business days after payment and stock confirmation. You will be contacted if an item requires additional processing time.
Products are packed to reduce movement, light exposure, and damage during transport. Inspect the parcel and product label after delivery.
Tracking information is provided when supported by the selected carrier. Delivery time depends on the destination and courier service.
Available delivery methods, final shipping cost, and the latest estimated delivery window are shown at checkout.
TB-500 is offered exclusively for laboratory and in vitro research. It is not intended for human or veterinary use.
Not necessarily. TB-500 is commonly associated with a synthetic fragment of thymosin beta-4. Research findings for the full-length protein cannot automatically be attributed to the shorter fragment.
No. Products in this catalog are research materials and are not presented as medicines, foods, cosmetics, or dietary supplements.
Follow the conditions printed on the label and any batch documentation. Keep the container sealed and protect it from light, heat, moisture, contamination, and repeated temperature changes.
The variant indicates the amount of material in the vial. Choose only according to the requirements of your validated laboratory protocol; it is not a dosage recommendation.
Where batch-specific documentation is available, it can be requested from Peptara Lab support before purchase. Always match any document to the lot number on the received product.
After payment and stock confirmation, in-stock orders are normally prepared for dispatch within 1–2 business days. Courier transit time is separate and depends on destination and service.
Do not use the material. Photograph the outer parcel, protective packaging, label, lot number, and damage, keep all packaging, and contact Peptara Lab support promptly for review.
