Trying to get reproducible immune activation data when your peptide degrades mid-study is a nightmare, and we've seen labs burn months on bad batches. That's why we run every lot of this thymosin alpha 1 through HPLC—≥99% purity is the floor, not the target, and the 3108.28 g/mol molecular weight is consistent within ±0.5% across vials.
You'll get a that reconstitutes cleanly in water or sterile saline—no clouding, no particulates. The 28-amino acid sequence (C129H215N33O55) holds up well at -20°C desiccated, but we've stored samples at -80°C for 18 months or so without a noticeable drop in activity.
Most buyers go with the 5mg or 10mg vials for, though the 1mg size is handy if you're just validating a protocol. It basically hits solubility within seconds at 1 mg/mL, but don't push past 5 mg/mL or you'll get some aggregation—that's just a fact of this peptide's hydrophobicity.
One thing you might not think to ask: the lyo cake can look slightly different between batches—sometimes more fluffy, sometimes denser—but HPLC trace and bioactivity are identical. We've had a few researchers flag this, so, and we'll send a photo of the actual vial if you need to match a previous order.
our company can do custom fill sizes, but teh MOQ for that is 100 vials, and lead time is about 2-3 weeks (usually faster if our company have the raw peptide stock). Standdard packaing ships within 5 business days, and every batch comes with a COA—just confirm if you need a third-party HPLC run alongside ours.
We can supply single vials for research orders — no minimum quantity for the 1mg to 10mg sizes. Bulk discounts apply for orders over 50 vials.
Yes, every batch comes with a CoA showing ≥99% purity by HPLC, plus identity and solubility test results. We can also share third-party testing reports upon request.
Once opened, store at -20°C in a desiccator and use within 30 days to maintain stability. The unopened shelf life is 24 months under proper conditions.
We offer custom labeling and can fill into 5mg or 10mg vials as standard. For other sizes or private labeling, just let us know the quantity — lead time is about 5-7 business days.
Yes, it dissolves readily in water or sterile saline. We recommend reconstituting just before use and keeping the solution at 2-8°C for up to 24 hours.
