TB-500

Thymosin beta-4 related material, studied for actin sequestration, cell migration and angiogenesis. Structurally unrelated to BPC-157 despite the two being routinely discussed together.

For laboratory research use only. Material is supplied as a research reference standard and is not approved by Health Canada. Protocols below are compiled from published literature and supplier documentation; they are reference information, not medical advice. Anyone with a health condition or on medication should speak to a physician first.

Before you begin

  • • Lot-matched certificate and laboratory notebook
  • • Calibrated pipettes, low-binding tubes and suitable PPE
  • • Validated solvent, assay reagents and model-specific SOP
  • • Appropriate positive, negative and vehicle controls

Required controls

  • Vehicle-only negative control
  • Untreated time-zero control
  • Validated migration control
  • Parallel cytotoxicity or viability assay

Reported protocol

Loading phase
2.0 mg to 5.0 mg twice weekly for 4 to 6 weeks
Maintenance phase
2.0 mg every 2 weeks
Route
Subcutaneous or intramuscular

Diluent

Sterile bacteriostatic water (0.9% benzyl alcohol) for multi-withdrawal stock, or sterile water for injection where a preservative-free stock is required by the assay.

Reconstitution concentrations

Solvent volume sets the stock concentration. Lower volume gives a more concentrated stock and smaller working aliquots; higher volume gives a more dilute stock that is easier to measure accurately.
