Thymosin Alpha-1

Price range: $75.00 through $106.00

Research-grade Thymosin Alpha-1 (Tα1, Zadaxin®), a synthetic 28-amino-acid thymic peptide (Ac-Ser-Asp-Ala-Ala-Val-Asp-Thr-Ser-Ser-Glu-Ile-Thr-Thr-Lys-Asp-Leu-Lys-Glu-Lys-Lys-Glu-Val-Val-Glu-Glu-Ala-Glu-Asn-OH), designed for controlled investigations of T-cell maturation, NK cell activation, dendritic cell function, cytokine balance, and broad-spectrum antiviral/immunomodulatory pathways.

Thymosin Alpha-1 is the N-terminally acetylated, fully synthetic version of prothymosin α fragment 1–28 originally isolated from thymosin fraction 5 (TF5). It is the only thymic peptide with worldwide regulatory approval (Zadaxin®) — licensed in 35+ countries for hepatitis B/C, vaccine adjuvant, and immune enhancement in sepsis/cancer. FDA orphan drug status for hepatocellular carcinoma and stage IV melanoma. This research-grade lyophilized peptide is produced under strict quality controls and provided with full analytical documentation, making it the gold-standard for immunology, virology, and oncology research.

Key Scientific

  • High-purity Thymosin Alpha-1 (≥ 99% by HPLC/MS, acetate salt form)
  • Verified 28-amino-acid sequence with correct N-terminal acetylation
  • Lyophilized formulation for maximum long-term stability
  • Full Certificate of Analysis (COA) with HPLC, MS, amino acid analysis, and bioactivity (T-cell proliferation assay)
  • Manufactured in GMP-aligned, ISO-compliant facilities
  • Ideal for T-cell/NK activation, TLR signaling, and antiviral immunity studies

Research-Referenced Attributes (Based on scientific literature & clinical trials; not therapeutic claims.)

  • Potent T-cell maturation & Th1 cytokine shift (↑ IL-2, IFN-γ, ↓ IL-10)
  • Enhances NK cell cytotoxicity and dendritic cell antigen presentation
  • FDA-approved (Zadaxin®) as HBV/HCV adjunct — 1.6 mg SC twice weekly → 40–60% sustained virologic response improvement
  • Phase 3 sepsis trial (n=360): 28-day mortality ↓ 9.0% vs. placebo (p=0.062, trending)
  • COVID-19 compassionate use: faster viral clearance and reduced inflammatory markers
  • Valuable in chronic viral infections, cancer immunotherapy, vaccine adjuvant, and critical illness research

Why Researchers Choose Nationwide Peptides Thymosin Alpha-1

  • Exact FDA-approved Zadaxin® sequence with correct N-terminal acetylation
  • Highest documented T-cell & antiviral potency among research suppliers
  • Transparent analytical data (HPLC >99%, MS confirmation of acetylation)
  • Trusted by immunology, virology, and critical care laboratories worldwide
  • Competitive research pricing with bulk options

Storage & Handling

  • Store lyophilized powder at –4 °F (long-term) or 39.2 °F (short-term)
  • Store in a tightly sealed container and protect from light, moisture, air exposure, and elevated temperatures.
  • Reconstitute only with bacteriostatic water or sterile saline (typical concentration 1.6–3.2 mg/mL)
  • Reconstituted solutions stable at 39.2 °F for up to 4 weeks; avoid repeated freeze-thaw cycles
  • Use appropriate PPE and aseptic technique
