Thymosin Alpha-1 Nasal Spray peptide Details
Thymosin Alpha-1 Nasal Spray — Research Grade | Pre-Formulated Liquid Solution
This nasal spray formulation delivers Thymosin Alpha-1 (Tα1) as a pre-formulated, sterile liquid solution for research use. No reconstitution is required — the product arrives ready for laboratory application via the nasal spray delivery format.
Thymosin Alpha-1 is derived from prothymosin alpha, a protein produced primarily by the thymus gland. It is a naturally occurring 28-amino acid peptide with a well-documented role in T-cell maturation, immune system development, and immunomodulation. Research has studied its broad immunomodulatory profile including effects on T-helper cell differentiation, dendritic cell maturation, NK cell activity, and cytokine production.
Nasal spray format note: This product is supplied as a metered-dose nasal spray bottle for research convenience. Intranasal delivery formats for immunomodulatory peptides are explored in preclinical research contexts. All use is strictly for laboratory and research purposes only.
⚠️ For Research Use Only — Not for human consumption. Requires 2nd Day Air or Next Day Air shipping (no ground shipping available).
Thymosin Alpha-1 Nasal Spray peptide Scientific Research
1. T-Cell Function and Differentiation Studies
Tα1 is commonly used to explore mechanisms of T-cell development, activation, and signaling. It has been shown to influence CD4+/CD8+ ratios and enhance effector responses in immunocompromised models.
2. Toll-Like Receptor (TLR) and Pattern Recognition Pathways
In vitro assays highlight Tα1's role in modulating TLR-mediated innate immune responses. It activates MyD88-dependent signaling, leading to upregulation of NF-κB and downstream cytokine expression.
3. Cytokine Modulation and Immune Balance
Thymosin Alpha-1 is utilized in research evaluating cytokine regulation, particularly IL-2, IFN-γ, and TNF-α. It has been shown to support immune balance in stress and inflammation models.
4. Antigen Presentation and APC Maturation
Experimental studies indicate enhanced dendritic cell maturation and increased expression of MHC class I and II molecules under Tα1 influence, supporting its use in antigen presentation and vaccine research paradigms.
5. Host Defense and Stress Response
Tα1 is employed in infection and immune-compromised models to examine its effect on restoring immune competence, supporting research into peptide-mediated resistance mechanisms and systemic resilience.

Handled correctly, stability holds
All peptides are supplied as sterile, lyophilized powder and are stable when handled correctly.
Store vials in a cool, dry place away from heat and direct sunlight.
For optimal longevity, keep lyophilized peptides refrigerated to help maintain integrity.
Use an appropriate research diluent (for example, BAC water). Store the reconstituted solution in the refrigerator and use within 20–30 days for best stability.
Minimize exposure to moisture and repeated freeze–thaw cycles. Follow your institution's safety procedures when handling research materials.
Frequently Asked Questions
PRODUCT & PURITY
This product is offered for laboratory and research use only. It is not intended for human consumption, medical use, therapeutic use, or veterinary use.
Yes, all of our products are sterile and sealed with a sterility plug and safety cap.
Our products undergo quality control internally at our lab and then 3rd party tested at Bioviridian (at their Texas facility) prior to shipment. All of our COA's are then posted on our site immediately upon receipt.
99% or higher. Period. The expected purity is listed on the individual product page or Certificate of Analysis, when available.
No. We are a manufacturing company and because these products are sold for research purposes only, we do not provide dosing, administration, or medical-use guidance.
Unless specifically stated otherwise, these products are not approved by the U.S. Food and Drug Administration for therapeutic or diagnostic use.
STORAGE & STABILITY
As a lyophilized powder, peptides are stable. Delays in shipments up to 7 days will have zero to minimal impact on efficacy of peptides. Most precautionary efforts must be made to maintain temperature consistency once reconstituted.
Store the product according to the storage recommendations provided on the label or accompanying documentation in your shipment. Proper storage helps maintain product integrity during its shelf life. Most peptides have an expiration date of 2 years if kept unreconstituted (lyophilized powder).
SHIPPING
Shipping times vary based on your location and the shipping method selected at checkout. We offer shipping options between 1 and 5 days.
No.
Once your order is processed, you will receive a shipping confirmation email with tracking information.
