What exactly is TB-500, and why do research programs pick the 5mg tier?
TB-500 is a 43-amino-acid synthetic sequence matching the actin-binding region of thymosin beta-4, studied in pre-clinical models of cellular migration and connective-tissue remodeling. The 5mg per vial tier is the standard entry point for small-cohort work and for programs still finalising working concentration — it keeps reconstitution volumes low and minimises waste when only a handful of exposures are planned.
What does this specific lot’s CoA cover?
Purity is characterised by reverse-phase HPLC and identity is confirmed by LC-MS against the theoretical 4963.4 Da monoisotopic mass. Lot certificates are catalogued to the product record as they clear the release queue.
How do I reconstitute a 5mg TB-500 vial?
- Warm the vial to room temperature; do not use heated water baths.
- Wipe the rubber stopper with an alcohol swab.
- Inject 1 mL of bacteriostatic water in a slow trickle down the inside wall so the peptide cake is not disrupted.
- Roll the vial between the palms until the cake dissolves fully — no vortexing, no shaking.
- Keep the reconstituted vial refrigerated at 2 to 8 °C and use within 30 days.
Should I order the 5mg or 10mg tier?
The 5mg tier suits protocol-development or small n-of-few cohorts where a single vial covers one full study arm. The 10mg tier is more economical when the same working concentration is being repeated across multi-week timelines and the extra mass will actually be drawn down before the 30-day post-reconstitution window closes.
How does TB-500 compare with BPC-157?
TB-500 is a thymosin beta-4-derived actin-binding fragment; BPC-157 is a 15-amino-acid pentadecapeptide reported in the literature under a cytoprotective and angiogenic framing. Because the two work through non-overlapping in-vitro pathways, co-exposure designs are common. Prescott carries BPC-157 (BC5, BC10) individually and as the BB10 5mg + 5mg blend.
