Buy Immune Research Peptides Australia: Thymosin Alpha-1 and KPV
Shop immune research peptides in Australia from Chainwell Peptide: the thymic immune modulator thymosin alpha-1 and the anti-inflammatory tripeptide KPV. Every lot is lab-tested with a matching certificate of analysis and dispatched from within Australia.
Thymosin Alpha-1
Thymosin alpha-1 is a 28 amino acid peptide first isolated from calf thymus tissue in 1977. The thymus is where T cells mature, and thymosin alpha-1 is studied for its effects on that process: T cell differentiation, dendritic cell activity and the signalling that coordinates an immune response. Under the name thymalfasin it has been approved as a medicine in a number of countries outside Australia, which gives it a longer clinical record than most research peptides.
We supply it as a 10mg lyophilized vial.
Thymosin Alpha-1 Is Not TB-500
The names cause constant confusion. Thymosin alpha-1 and thymosin beta-4 were both isolated from the same thymus extract, but they are unrelated peptides with different sequences and different research uses. TB-500 is a fragment of thymosin beta-4 and is studied in tissue repair, not immune modulation. If your protocol names thymosin alpha-1 or thymalfasin, TB-500 is not a substitute.
KPV: An Anti-Inflammatory Tripeptide
KPV is lysine-proline-valine, the last three amino acids of alpha-MSH. It keeps the anti-inflammatory activity of the parent hormone without its effects on pigmentation, and is studied for its action on the NF-kappaB inflammatory pathway. Much of the research is in gut inflammation models, helped by the finding that KPV is carried into intestinal cells by the PepT1 transporter. It is supplied as a 10mg vial, and is also one of the four peptides in KLOW.
Which Immune Peptide Suits Your Research?
Choose thymosin alpha-1 for work on adaptive immunity and T cell function, and KPV for inflammation, particularly in the gut. They act on different arms of the immune system, so studies that span both usually order the two as separate vials. For immune-adjacent research at the cellular level, see also our mitochondrial peptides.

Immune FAQ
What is thymosin alpha-1?
+
Thymosin alpha-1 is a 28 amino acid peptide first isolated from thymus tissue in 1977 and studied as an immune modulator, particularly for T cell maturation. It has been approved as thymalfasin in several countries outside Australia.
Is thymosin alpha-1 the same as TB-500?
+
No. Both came from the same thymus extract, but thymosin alpha-1 is a 28 amino acid immune modulator, while TB-500 is a fragment of thymosin beta-4, studied in tissue repair.
What is KPV peptide?
+
KPV is the tripeptide lysine-proline-valine, the last three amino acids of alpha-MSH. It is studied for anti-inflammatory activity, especially in gut models, and is also one of the peptides in KLOW.
Where can I buy thymosin alpha-1 in Australia?
+
You can buy thymosin alpha-1 in Australia from Chainwell Peptide as a 10mg lyophilized vial. Every lot has a lot-matched certificate of analysis, and orders paid before 3pm ship the same day.
