Immune modulation and T-cell maturation

Published research describes TA-1 promoting the differentiation of thymocytes into mature T-cells and modulating TLR2/TLR9 signalling on dendritic cells and monocytes.

  • T-cell maturation and CD4/CD8 differentiation research
  • Dendritic cell and toll-like receptor signalling
  • Cytokine profile modulation studies

Sterile storage protocol

Store lyophilized TA-1 at -20°C protected from light. Once reconstituted with bacteriostatic water, refrigerate at 2–8°C and avoid repeated freeze-thaw cycles.

  • 5mg vial + 2mL BAC water = 2.5mg per mL
  • Lyophilized: -20°C, desiccated, light-protected
  • Reconstituted: 2–8°C, single working aliquot preferred

Frequently asked questions

How is thymosin alpha 1 reconstituted?

Add 2mL of bacteriostatic water to a 5mg vial for a 2.5mg/mL solution, swirl gently and refrigerate.

How long is reconstituted TA-1 stable?

Refrigerated at 2–8°C and protected from light, reconstituted material is typically used within the stability window stated on the lot COA.
