Shared research areas
- Tendon and ligament fibroblast models
- GI mucosal repair assays (in vitro)
- Wound-healing scratch assays
Key differences
- Material type differs — BPC-157 is supplied as synthetic pentadecapeptide, TB-500 as actin-binding peptide fragment.
- Primary literature focus — Tendon and ligament fibroblast models vs Cell migration assays.
- Catalog availability — BPC-157 is stocked by VaultLabs; TB-500 is covered as a reference monograph only.
Storage comparison
Both are stored at 2–8 °C (lyophilized, sealed), so they can share the same cold-chain and inventory conditions. BPC-157: 2–8 °C sealed storage for lyophilized material. TB-500: Lyophilized material: 2–8 °C sealed.
