02Verify your vial

Three steps from label to lab.

  1. 01Scan the label

    Every vial label carries a QR code. Point your phone camera at it.

  2. 02Land on its record

    The code opens that lot's certificate with every assay value. No phone? Type the lot from your packing slip on Verify a lot.

  3. 03Check it with the lab

    Each signed certificate links to the lab's own verification page, so the report can be confirmed independently of us.

04In the lab

How Thymosin Alpha-1 is studied to work.

Thymosin alpha-1 is a 28-amino-acid peptide first isolated from thymus tissue. In laboratory research it signals through Toll-like receptor pathways (MyD88, TRAF6, NF-kB) in dendritic cells and macrophages and induces the IDO enzyme in dendritic cells.

Compound

Thymosin Alpha-128-amino-acid peptide first isolated from the thymus

  1. Dendritic cells

    Dendritic cells

    • TLRs
    • MyD88
    • p38 MAPK
    • NF-kB

    Endpoint studied

    Maturation and IL-12

    Dendritic cells matured and made IL-12 through MyD88-dependent Toll-like receptor and p38/NF-kB signaling.

    Romani 2004 · PMID 14982877

  2. IL-6 induction

    Macrophages, fibroblasts

    • TRAF6
    • IKK
    • NF-kB

    Endpoint studied

    IL-6 expression

    IL-6 induction needed IKKbeta and TRAF6; a TRAF6, p62, PKC iota/zeta and IKK signalsome formed.

    Zhang 2005 · PMID 15905851

  3. Tolerance signaling

    Dendritic cells

    • TLR9
    • IDO

    Endpoint studied

    IL-10, regulatory T cells

    IDO expression and activity rose, needing TLR9 and type I interferon receptor signals; IL-10 followed.

Email supportContact page
01Which lot will I receive?

The current released lot, SA-TA1-2610. Scan the QR code on the vial label to open its certificate. The lot number is also on your packing slip, and the full certificate is here.

02Is the certificate real, and can I check it?

Every certificate is issued by an independent laboratory. Each lot has its own public record page with every assay value, and a link to verify the report on the lab's own site once the signed PDF is posted.

03Why does net content show more than 10 mg?

Vials are filled slightly over the labelled mass so that every vial meets it. Net content is measured on each lot and published as a number, not a pass.

04What if the vial arrives without vacuum or damaged?

Email [email protected] within 7 days with your order number and a photo and we will replace it.

05When will it ship?

Orders by 2 PM ET on a weekday ship the same day, with tracking emailed when the label prints.

06Is Thymosin Alpha-1 for human use?

No. It is sold strictly for in-vitro laboratory research and is not for human or animal use of any kind.
