A quick word from the lab
So — why Thymosin Alpha-1?
Look, you've got a shortlist and you're comparing suppliers. Fair. Here's the honest pitch: Thymosin Alpha-1 is one of the most-requested reference standards on our bench, and the reason people keep coming back is boring — it's the paperwork. Every vial ships with a batch-specific Certificate of Analysis: HPLC trace, mass-spec confirmation, water content, endotoxin where relevant. If the numbers on the CoA don't match what's on the label, we don't ship it.
What you're actually paying for
The vial is the cheap part. What costs money is the assay work behind it, the cold-chain handling, and a UK lab that will actually answer the phone if something looks off in your data. You're not buying a powder — you're buying a reference standard you can defend in a method-validation review.
Why buy it from the UK
No customs hold, no duty surprise, no parcel sitting in a Rotterdam warehouse for three weeks. Order before 2 pm on a working day and it leaves our facility the same afternoon, tracked. If a vial arrives damaged, we reship — no argument, no forms.
How researchers use it
Common bench applications
Receptor-binding assays
Use as a characterised ligand in radioligand or fluorescence-based binding studies against the relevant receptor panel.
Analytical method development
Reference standard for HPLC and LC-MS method development, calibration curves, and identity confirmation of unknown lots.
In-vitro signalling studies
Cell-culture work exploring downstream signalling, dose-response curves, and comparative potency versus related analogues.

“Consistent thymic peptide reference with a clean CoA every batch.”
“UK dispatch meant next-day arrival — no customs delay.”
“Presentation and documentation are a clear step above.”
Frequently asked
What vial sizes of Thymosin Alpha-1 are available in the UK?
Two: 5mg (£74) and 10mg (£134). The 10mg vial reduces the number of reconstitutions and freeze-thaw cycles across a longer protocol.
How is Thymosin Alpha-1 reconstituted?
Add bacteriostatic water slowly down the vial wall — 2ml into a 5mg vial gives 2.5mg/ml. Do not shake; swirl gently until fully dissolved. Our reconstitution calculator works out any concentration for you.
How should it be stored?
Store the lyophilised vial at 2–8 °C away from light. Once reconstituted it is typically stable for around 28 days refrigerated.
What purity documentation is supplied?
Every order includes the batch-specific Certificate of Analysis for that vial — HPLC purity plus mass spectrometry identity confirmation. Past batches are in our CoA library.
Is a Certificate of Analysis included?
Yes. Every batch is HPLC and mass-spec assayed by an independently accredited third-party laboratory, and the batch-specific CoA is included with the parcel and available on request via our CoA library.
