Thymosin Alpha-1 (TA-1) Testing Methodology

Our analytical workflow for Thymosin Alpha-1 (TA-1) follows USP <1225> guidance for validated chromatographic methods. Each lot is processed by a credentialed analyst with documented chain of custody.

  1. Step 1

    Sample intake & chain of custody

    Your Thymosin Alpha-1 (TA-1) sample (0.5-1 mg lyophilized) is logged at our Florida lab with a unique ID, photographed, and stored at -20 °C until analysis.

  2. Step 2

    Reverse-phase HPLC purity

    Thymosin Alpha-1 (TA-1) is dissolved in mobile phase and run on a C18 column with a water/acetonitrile gradient containing 0.1% TFA. UV detection at 214 nm quantifies the main peak and any related impurities.

  3. Step 3

    LC-MS identity confirmation

    An aliquot is analyzed by liquid chromatography-mass spectrometry. The observed monoisotopic mass is compared against the theoretical molecular weight (3108.32 g/mol) for Thymosin Alpha-1 (TA-1) to confirm identity.

  4. Step 4

    Impurity profiling & reporting

    Related substances, truncations, and oxidation products are quantified. Findings are compiled into a signed Certificate of Analysis with chromatograms, mass spectra, and analyst interpretation.

Thymosin Alpha-1 (TA-1) Purity Notes

Recommended research-grade purity for Thymosin Alpha-1 (TA-1) is ≥95%. Lot-to-lot variation is common with solid-phase synthesis, so independent verification matters.

Common impurities to watch

  • Truncated sequences from incomplete coupling
  • Deletion peptides missing one or more residues
  • Oxidation of methionine, tryptophan, or cysteine
  • Residual TFA, acetate, or solvent counter-ions
  • Aggregates and dimers from improper storage

What our COA confirms

  • Main peak purity by HPLC area %
  • Observed vs theoretical mass (3108.32 g/mol)
  • Named impurities ≥ 0.1% area
  • Net peptide content where applicable
  • Method, column, and instrument metadata

Thymosin Alpha-1 (TA-1) Handling, Storage & Safety

Guidance below is for laboratory and research personnel only. Thymosin Alpha-1 (TA-1) is supplied for research use and is not intended for human or veterinary use.

Storage

Store lyophilized Thymosin Alpha-1 (TA-1) at -20 °C, protected from light and moisture. After reconstitution, aliquot and store at -80 °C; avoid repeated freeze-thaw cycles.

Reconstitution

Reconstitute in bacteriostatic or sterile water in a clean environment. Allow vials to reach room temperature before opening to prevent moisture condensation on the powder.

PPE & shipping

Handle with gloves, lab coat, and eye protection. Ship samples to ACS overnight on dry ice or cold packs in a rigid, leak-proof container with a packing slip referencing your quote.
