Description
What Is TB-500 10mg? (In Plain English)
TB-500 is a lab-made version of a small protein fragment that cells rely on when they need to move. Picture a repair crew that has to lay its own track before it can roll toward a damaged spot — this peptide is part of how a cell decides when to lay that track and when to pick it back up. Researchers use it in wound-closure experiments with cultured cells and with mice.
TB-500 10mg — Research Overview
TB-500 is a synthetic thymosin β-4 (Tβ4) derivative supplied here as a 10 mg lyophilized vial. Tβ4 is the principal G-actin-sequestering peptide in mammalian cells, and the LKKTETQ heptapeptide motif within it is described in the literature as the minimal actin-binding region. Preclinical publications associate the molecule with keratinocyte and endothelial cell migration, corneal epithelial repair models, and altered fibrosis markers in rodent tissue.
Primary Research Areas
- Dermal wound-closure models — investigated in rodent excisional and incisional wound studies
- Corneal epithelial repair — studied in vitro and in animal ocular-surface models
- Endothelial migration — examined in angiogenesis and vessel-sprouting assays
- Fibrosis markers — investigated in animal models for collagen deposition and myofibroblast endpoints
- Comparative repair-peptide work — benchmarked against BPC-157 and combination preparations

Why Researchers Source TB-500 10mg from Dissolv Labs
Dissolv Labs is a research-supply company based in Southern California. Orders are picked, packed, and shipped domestically from our SoCal facility, so most U.S. laboratories see short transit times and no international customs delay.
Every vial ships as a complete kit. Each TB-500 10mg vial is paired with its own bacteriostatic water reconstitution vial, so the material arrives ready to prepare in the lab without a separate diluent order. Compounds are supplied lyophilized in sealed, labeled vials with lot identification, and analytical documentation is available on request.
TB-500 10mg — Frequently Asked Questions
What is TB-500 10mg used for?
TB-500 10mg is supplied strictly as a research chemical for in vitro and laboratory research applications. The literature investigates it in cell-migration, wound-closure, and fibrosis-marker models across cultured cells and rodents. It is not for human or veterinary use.
Is TB-500 the same thing as thymosin beta-4?
Not exactly. Thymosin β-4 is the full 43-residue endogenous peptide, while TB-500 is the research designation for synthetic material derived from it — supplied either as the full sequence or as the acetylated LKKTETQ-containing fragment. Publications use both names, so literature searches should include each term, and lot documentation should be checked for the exact material supplied.
How is TB-500 10mg stored and reconstituted?
The 10 mg vial arrives lyophilized and sealed with lot identification, and is kept cold and protected from light until prepared. A matched bacteriostatic water vial ships in the same kit, so reconstitution can be performed in the lab without a separate diluent order. Reconstituted material is refrigerated per standard laboratory practice.
Where can I buy TB-500 10mg for sale?
TB-500 10mg is available from Dissolv Labs, a Southern California research-supply company. Every order ships domestically from our SoCal facility as a complete kit including the reconstitution vial. Lot-specific analytical documentation is available on request for qualified researchers.
Research Use Only
TB-500 is sold exclusively as a Research Use Only (RUO) chemical. It is not a drug, supplement, cosmetic, or food, and it is not intended for human or veterinary use, ingestion, injection, topical application, or any form of consumption. It is intended solely for licensed laboratory research by qualified professionals. Dissolv Labs makes no medical, therapeutic, or diagnostic claims of any kind. By purchasing, the buyer confirms they are a qualified researcher and accepts full responsibility for lawful handling, use, and disposal.
Bacteriostatic (BAC) water is included free with every order.

Exact quantity and concentration are listed in the product title and variant options above. The figures above are release specifications — the measured result for your particular lot is stated on its Certificate of Analysis.
Documentation & Testing
Every batch is tested before release. Testing covers four checks: identity by mass spectrometry, purity by HPLC against a ≥99% release threshold, content verification against the labelled mass, and batch release tied to a specific lot number.
To request the Certificate of Analysis for your vial, email us with your order number or the lot number printed on the label. We do not gate documentation behind a form or a purchase.

Handling & Storage
Lyophilized peptides are relatively stable during transit. Arriving at room temperature is not cause for concern — the cold pack is a margin of safety rather than a pass/fail condition.
Sealed vials of lyophilized material are typically stored refrigerated or frozen and protected from light. Handling protocols for a specific compound are determined by the researcher and their institution; we supply the material and its documentation.
Shipping & Returns
Orders placed before the daily cut-off are dispatched the same business day from Southern California in insulated packaging with ice packs. Tracking is issued at dispatch.
If a shipment arrives damaged, if vial contents appear inconsistent with the specification, or if the lot number on your vial does not match the certificate we provide, contact us and we will resolve it.
Because these are temperature-sensitive laboratory materials, opened vials cannot be returned to stock.
