THYMOSIN ALPHA-1 FAQ
Where is thymosin alpha 1 for sale?
You can buy thymosin alpha 1 from Blank Peptides in 10mg vials, made in our cGMP labs in the USA. Every vial ships with a lot-matched certificate of analysis published before you order, and this SKU was the first in our range to carry a Blank-branded certificate. No prescription is needed, and processing time is within 1 business day.
What is thymosin alpha-1?
Thymosin alpha-1 is a 28-amino-acid peptide originally isolated from thymosin fraction 5, a thymus gland extract. Research has focused on T cell maturation, dendritic cell activity and toll-like receptor signalling, making it one of the more studied immunomodulatory peptides. Much of the work sits in cell culture and animal infection models.
What purity is your thymosin alpha-1?
Greater than 99%. Each production lot is assayed by HPLC and mass spectrometry at our lab, then independently confirmed at Freedom Diagnostics or Horizon Analytical, with bacterial endotoxin testing on the batch. Blank Peptides issues the COA against the lot number printed on your vial. Acetylated N-terminal peptides need careful assay work, so the second run matters.
How do I reconstitute thymosin alpha-1 10mg?
Add 1mL of bacteriostatic water for 10mg/mL, following our standard of 1mL per 10mg. Let the solvent run down the inside of the vial rather than striking the cake directly, then swirl slowly until clear. Do not shake. Foaming makes accurate withdrawal harder and stresses the peptide unnecessarily.
How should thymosin alpha-1 be stored?
Sealed lyophilized vials at -20C, kept dark and dry. Ambient temperatures during shipping do no harm to freeze-dried material. Once reconstituted, store at 2 to 8C and use the solution within a few weeks of laboratory work. Aliquot into sterile vials if the protocol will run beyond that.
Thymosin alpha-1 vs TB-500: are they related?
Only by name. Thymosin alpha-1 and thymosin beta-4 were both isolated from the same thymus extract, but they are unrelated sequences with unrelated functions. TB-500 is a beta-4 fragment studied for actin binding and cell migration. Thymosin alpha-1 is an immunomodulatory peptide studied through T cell pathways.
How fast do thymosin alpha-1 orders ship?
Processing time is within 1 business day. Vials leave from inside the USA in plain outer packaging with no compound names showing, and freeze-dried peptide needs no cold pack for domestic transit. Tracking is emailed at label creation. Because this SKU carries a Blank-branded certificate, check the lot number on the paperwork against the vial when the box lands.
Is thymosin alpha-1 approved as a medicine?
It is approved in some countries outside the United States, but it holds no FDA approval here and the material we sell is unapproved research grade compound. It is not a drug, supplement or veterinary product as supplied, and it is not for human use. Ordering confirms laboratory research use only.
