Common Questions
TA-1 — FAQ
What is TA-1?+
TA-1 is a Thymosin Alpha-1 supplied for laboratory research. Thymic peptide studied in vitro for T-cell maturation pathway modeling, dendritic cell activation signaling analysis, and immune-response mechanism research.
Is TA-1 the same as Thymalfasin or Zadaxin?+
Yes — TA-1 is Thymosin Alpha-1, also known as thymalfasin and studied as the active compound in the branded product Zadaxin. It is researched for T-cell maturation and immune-response signaling.
What is lyophilized TA-1, and how is it reconstituted?+
TA-1 is supplied as a lyophilized (freeze-dried) powder — a dehydrated form that keeps the peptide stable during shipping and storage. In the laboratory it is reconstituted (returned to liquid form) using a solvent such as bacteriostatic water, added slowly against the side of the vial, which is then swirled gently — never shaken — until the powder fully dissolves. All handling is for in vitro research use only.
How should TA-1 be stored?+
Store the lyophilized TA-1 powder at -20°C, protected from light and moisture, where it remains stable long-term. Once reconstituted, keep it refrigerated (2-8°C) and use it within the timeframe appropriate for your research protocol.
What is the purity of TA-1, and how is it tested?+
Every batch of TA-1 is produced to a purity of 99% or higher. Purity and molecular identity are verified using standard analytical methods — high-performance liquid chromatography (HPLC) to measure purity, and mass spectrometry (MS) to confirm the peptide's molecular weight.
