What is Immune Signalling Pair?

The Immune Signalling Pair combines Thymosin Alpha-1 with LL-37, covering thymic and host defence mechanisms in innate and adaptive immune cell models. The two act through separate pathways, which is why they are supplied together.

  • Thymosin Alpha-1 10mg vial, a 28 amino acid thymic peptide
  • LL-37 5mg vial, the 37 amino acid human cathelicidin peptide

Immune Signalling Pair research applications

  • NF-kB and interferon-stimulated response element reporter assays in HEK293 lines transfected with TLR2 or TLR9, the Thymosin Alpha-1 readout
  • Broth microdilution and SYTOX Green uptake as membrane permeabilisation readouts, the LL-37 arm
  • FPR2 calcium flux and transwell chemotaxis in differentiated HL-60 cells, with antagonist controls

After reconstitution
Reconstitute with bacteriostatic or sterile water, store at 2 to 8°C and avoid repeated freeze-thaw cycles. No stability-tested shelf life is published for this product.

Immune Signalling Pair questions

Where can I buy Thymosin Alpha-1 and LL-37 together in Australia?
NuVion stocks them together as the Immune Signalling Pair: one Thymosin Alpha-1 10mg vial and one LL-37 5mg vial in a single order, posted from Australian stock on a tracked express service. This pair is supplied as a research material only and is not on the Australian Register of Therapeutic Goods.
What is in the Immune Signalling Pair?
Two vials: Thymosin Alpha-1 10mg and LL-37 5mg. Each compound comes in its own sealed vial, so nothing is pre-mixed. Bacteriostatic water is sold separately.
How much does the Immune Signalling Pair cost?
The current price and stock are shown at the top of this page in AUD, next to what the same vials cost at their regular prices when bought one at a time.
What is the difference between Thymosin Alpha-1 and LL-37?
Thymosin Alpha-1 is a 28 amino acid thymic peptide. LL-37 is the 37 amino acid human cathelicidin peptide.
Is the Immune Signalling Pair tested as one product?
No. A pair is not tested as a pair. Each vial has its own published result, and the table on this page lists them.
How do Thymosin Alpha-1 and LL-37 differ in charge?
LL-37 carries a net charge of about +6 at neutral pH and folds into an amphipathic helix. Thymosin Alpha-1 has an acetylated N-terminus, which removes its terminal positive charge.
Does either peptide in the Immune Signalling Pair have a fixed structure in solution?
Neither does in plain buffer. Thymosin Alpha-1 is largely unstructured in aqueous buffer and gains helical content in membrane-mimicking solvents. LL-37 is unstructured in water at low ionic strength and folds as salt rises or when it meets anionic lipid.
