Thymosin Alpha-1 10mg

Thymosin Alpha-1 is a 28-amino-acid acetylated peptide derived from prothymosin alpha. It is studied for effects on T-cell maturation, dendritic cell activation and Toll-like receptor signalling, and is approved in several countries as Zadaxin.

About Thymosin Alpha-1 10mg

Unlike Thymalin, which is a tissue-derived fraction, Thymosin Alpha-1 is a single defined sequence, which makes it the more tractable of the two for mechanistic work. Its activity appears to run largely through TLR2 and TLR9 on dendritic cells, shifting T-cell differentiation toward a Th1 profile. That mechanism underpins its approved use as an immune adjuvant in hepatitis B and C in a number of countries, and it accumulated a large dataset during COVID-19 research. Its immune activity is context-dependent, restoring depressed responses more than amplifying normal ones.

Storage and reconstitution

Store lyophilized peptide at -20°C in a dry, dark environment. Reconstitute in bacteriostatic water. Once reconstituted, store at 2-8°C and use within 30 days. Avoid repeated freeze-thaw cycles. Lyophilized powder is stable at room temperature for shipping and short-term storage.

Shipping within Canada

Orders placed before 2:00 PM Pacific on a business day are packed and dispatched the same day. Orders placed after that cut-off, or on a weekend or statutory holiday, are dispatched on the next business day. Parcels leave British Columbia, Canada and travel entirely within the country, so nothing on this order crosses a border, clears customs or is held by CBSA. Orders over CA$200 ship free; see the shipping page for transit times by province.
