Per vial, USD
Thymosin Alpha 1 is quoted rather than listed. It is synthesized against your order, so the rate depends on quantity and fill weight — send the sheet and a person calls you back with a figure and a date.
Ordering at volume
This is a quote-only line. It is not on the shelf; the peptide is synthesized after the order is placed, so the lead time is longer than any stocked line and is stated on the quote rather than being a stock-picking interval. The quote also fixes the fill weight, which is agreed for the run rather than chosen from a list, and it lists the documentation that will be available for the lot.
Quantity works differently from the stocked lines. Run size shapes the per-vial figure on a made-to-order line far more than it does on a stocked one, so a buyer who can consolidate several months of need into one run should say so at quote. A buyer who needs a small quantity quickly should say that too, and the desk will answer plainly what can be done.
Everything an order of this compound depends on should be in the written quote: fill weight, count, acetylation confirmed on the certificate, lead time, and whether the order can be split into deliveries. Read the quote back against your specification before confirming, because a made-to-order lot is vialed to the specification on the quote. Contract pricing above 10,000 vials of one compound also applies to made-to-order lines.

What the material is
Thymosin alpha 1, often written Ta1, is a synthetic peptide of twenty-eight amino acid residues with an acetyl group on its N-terminus, and a molecular weight of 3,108.28 g/mol. The acetyl cap is part of the defined structure rather than a manufacturing variant, and a certificate for this compound should report the acetylated species as the main peak.
Supplied form is a white to off-white lyophilized solid, vialed and sealed. Because it is synthesized to order rather than kept on the shelf, the vial format and fill are agreed at quote, and the cake appearance follows the freeze-drying run for that batch; a finished lot should present a uniform cake across the vials, and the certificate records the batch appearance.
Storage and reconstitution
Sealed vials keep best frozen at −20 °C, in the dark, in a dry container. The acetylated N-terminus does not change the storage picture; the lyophilized solid is stable for a long period under seal and tolerates the brief warming of a courier transit.
The peptide takes up sterile water or an aqueous buffer near neutral pH without difficulty. The solvent is added slowly to the wall of the vial and the cake collapses into it; gentle rolling finishes the job. The solution should be clear and free of particles.
Dissolved material should be refrigerated, kept out of light and used over days, not weeks. Split into single-use portions before freezing rather than refreezing a working volume, since every thaw costs a dissolved peptide some of its integrity.
Buying questions
Why is Thymosin Alpha 1 quote-only rather than priced on the site?
Because it is made to order. Each lot is synthesized for the buyer, so the price depends on the run size and the fill weight requested and cannot be read from a fixed ladder. A written quote is usually returned the same business day; see how to order.
What is the lead time on a made-to-order Thymosin Alpha 1 lot?
Longer than any stocked line, because synthesis, purification, freeze-drying and release testing all happen after the order is confirmed. The exact figure is on the quote and depends on run scheduling at the time.
What fill weights is Thymosin Alpha 1 available in?
None are fixed. Because the line is vialed to order, the fill weight is confirmed at quote to match your specification.
Does the certificate confirm the N-terminal acetylation?
It reports the observed mass, which distinguishes the acetylated peptide from the free-amine form, and the main-peak purity by chromatography. Certificates are lot-specific and available on request through COA requests.
