About this peptide

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.

A pair of thymic and host defence peptides used in innate and adaptive immune cell models.

What is tested in this pair

This pair contains two products, each supplied in its own vial and each tested on its own. The table lists the published result for every component.

Component	Purity	Laboratory	Analysed	Certificate

LL-37	99.85%	Janoshik Analytical	18 Mar 2026	View

A pair is not tested as a pair. Each vial carries its own documentation, which is what the table above reflects.

Why buy this peptide from NuVion

Products across the NuVion range are sent to Janoshik Analytical, an independent laboratory, for purity by RP-HPLC and identity by mass spectrometry. Each product page shows its own testing status, so you know before you order exactly what has been measured and what has not.

Testing status on every page

Where a product has a published result you get the measured purity, the date it was analysed and the full certificate. Where there is not one, the page says so plainly instead of leaving a gap you have to notice.

Australian stock, domestic post

Nothing crosses a border after you order. Stock is held in Australia and goes out in plain outer packaging with protective inner packing, tracked from dispatch.

Specifications

Handling and storage

Before reconstitution

Keep the sealed vial cool, dry and out of direct light. This is general handling practice for lyophilised peptides, not validated stability data for this product.

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, so set any working period in the laboratory using it.

Questions

How do I know the vial contains what the label says?

Most of our range goes to Janoshik Analytical for RP-HPLC purity and mass spectrometry identity. Where a product has a published result, its certificate sits on this page with the measured purity and the date it was analysed, and where the result is held on Janoshik's own server the report opens there. Not every product has a published result yet. If this page does not show one, ask us and we will tell you where it stands.

What purity is this peptide and who tests it?

Testing is done by Janoshik Analytical, an independent laboratory used widely across the peptide research sector. Purity is measured by reverse phase HPLC and identity is confirmed by mass spectrometry. Where this product has a published result, the exact figure and the full certificate are shown further up this page.

How should this peptide be stored?

Keep the vial sealed, cool, dry and out of direct light. Once made up with bacteriostatic or sterile water, store it at 2 to 8°C and avoid repeated freeze-thaw cycles. That is general laboratory handling practice for lyophilised peptides. We do not publish a stability-tested shelf life for this product, so the working period should be set by the laboratory using it.

How fast will it arrive, and what turns up at the door?

Stock is held in Australia and most orders leave within one business day, arriving in 1 to 2 business days on a tracked express service. Orders go out in plain protective packaging, and every order is tracked from dispatch.

Do you ship this peptide anywhere in Australia?

Yes. Stock is held in Australia and posted to every state and territory, so nothing crosses a border after you order. Shipping is a $15 flat rate on a tracked express service, free on orders over $200, tracked from the moment the label is printed.

Can I order this peptide at wholesale volume?

Yes. We supply research groups, institutions and distributors ordering at volume. Get in touch with the quantities you need and we will come back with pricing and lead times.

What if my order arrives damaged or something is wrong?

Message us and we will fix it. A damaged vial, a wrong item, or a product that falls outside its stated specification on receipt gets a reply within one business day and a replacement or full refund. Beyond that, these are research materials, so ordinary change-of-mind returns are not something we can accept. Full terms are in the returns policy.
