Thymosin Alpha-1 5mg

Thymosin Alpha-1 5mg from Peptira is 5mg of Thymosin Alpha-1 in a sealed glass vial. Thymosin Alpha-1 is a thymic peptide. It’s for in-vitro and lab research only.

Thymosin Alpha-1 at a glance

Thymosin alpha-1 is a 28-amino-acid peptide first isolated from thymus tissue. It acts on T-cell maturation and innate immune signaling.

A synthetic form, thymalfasin (Zadaxin), is approved in some countries outside the US for hepatitis B and C.

How Thymosin Alpha-1 works

Thymosin alpha-1 acts on toll-like receptors, especially TLR2 and TLR9, on dendritic cells and other immune cells. That activates downstream signaling that helps T cells mature and shapes the response toward Th1 immunity.

It’s studied as an adjuvant alongside vaccines and in chronic viral infection models, where the goal is a stronger T-cell response without broad overstimulation.

What the research says about Thymosin Alpha-1

Clinical work on thymalfasin covers chronic hepatitis B and as an immune adjuvant, reviewed by Goldstein and colleagues.

Lab studies describe its action through toll-like receptors on dendritic cells.

The primary literature is on PubMed, run by the US National Library of Medicine. Here’s a search for Thymosin alpha-1 studies to start from.

How Thymosin Alpha-1 compares

Thymosin Alpha-1 5mg is easier to place once you see it next to the compounds it’s usually compared with. Thymosin Alpha-1 is a 28-amino-acid thymic peptide, approved in several countries as thymalfasin. The others:

• Thymalin is a calf-thymus peptide complex from Khavinson’s program, registered in Russia as an immune medicine
• LL-37 is the only human cathelicidin, an antimicrobial peptide that also signals in wound repair
• VIP is a 28-amino-acid neuropeptide that relaxes smooth muscle and calms immune cells

These are all studied in immune research, but at different points: the thymus peptides on T-cell maturation and signaling, LL-37 on direct antimicrobial action and VIP on calming inflammation. See them all on our immune peptides page.

Thymosin Alpha-1 5mg quality notes

The vial label shows the compound and the amount. For anything your lab needs on file beyond that, email Peptira support with the product name before you place the order.

Labs that check material in-house normally confirm identity with mass spectrometry, which checks the molecular weight, and measure purity with HPLC, which separates the main compound from anything else in the sample.

If you run a long study, try to order everything you need at once and log it when it arrives. It removes one variable from your results.

Reconstituting Thymosin Alpha-1 5mg

Here’s the math for 5mg of powder:

• 1mL of bacteriostatic water gives 5mg/mL
• 2mL of bacteriostatic water gives 2.5mg/mL
• 3mL of bacteriostatic water gives 1.67mg/mL

Choose the volume that suits your measurements. Mark the vial with the concentration and date so nobody has to guess later.

Most labs use sterile bacteriostatic water. We stock bacteriostatic water in 3mL, 10mL and 30mL sizes. Warm the sealed vial to room temperature, add the water slowly along the glass wall and swirl gently until it’s clear. Never shake it.

How to store Thymosin Alpha-1 5mg

The dry powder keeps best cold and dark. A freezer at -20°C is right for long-term storage. After reconstitution, store it in the fridge at 2 to 8°C and finish it within roughly four weeks.

Let a frozen vial warm up to room temperature before you open it. Cold glass pulls moisture out of the air, and moisture is what degrades dry peptide.

Planning a study with Thymosin Alpha-1 5mg

Work out the total amount before you order. Add up what each arm of the study uses across every time point, then divide by 5mg. Round up by one vial so a spoiled sample or a repeat run doesn’t stall the project.

Only reconstitute what you’ll use in the next few weeks. Sealed vials stay stable in the freezer, while a mixed vial should be finished within about 28 days.

If you order more than one vial, check that the batch numbers match before you start. Running a whole study on one batch removes one variable.
