4813.0 g/mol is the molecular weight, which is actually pretty useful info for calculating molarity when you're prepping solutions — it's a big peptide, so don't expect it to dissolve in water without DMSO first.
We've been shippng this batch at ≥99% by HPLC, and what that means in practice is cleaner chromatograms and fewer unknowns in your assay — it's suitable to most in vivo models, but we do see better results in binding studies compared to some 95% grade materail. Storage is strictly -20°C in the dark, or you'll lose activity fast (usually within weeks at room temp, ask anyone who's left it out).
The CAS is 2023788-19-2, which is the tirzepatide (LY3298176) sequence, and it come as a white to off-white powder in a vial with desiccant — 50mg or 100mg per vial, just specify. Also, we don't recommend this for anything near human use (it's research-only, full stop).
Honestly, the common concern we get is stability — it's soluble in DMSO, but once reconstituted, it degrades noticeably after 2 or 3 freeze-thaws unless you aliquot it immidiately. We usually have stock in the US warehouse, but lead time form production site is about 15 days or so for custom quantities.
GMP and ISO9001 are the qualiy standard here, so you'll get a COA with every batch — HPLC trace, mass spec, and endotoxin results, typically within 2-4 weeks of order. Most buyers go with the 50mg vials for lab work, but if you need bulk, our company can do larger drums.
Yes, each batch is tested by HPLC and the certificate of analysis is available on request – that ≥99% is verified, not just a claim.
We don't have a strict MOQ; you can order as little as one vial for lab testing, but bulk pricing kicks in at 10+ vials.
Keep it at -20°C, protected from light, in the original vial with desiccant. Once reconstituted, use immediately or store at -20°C for short-term.
Absolutely – we can supply the GMP and ISO9001 certificates along with the COA for each batch. Just ask when you place the order.
We can do custom labels or packaging for bulk orders, but standard vial packaging is what we ship for smaller quantities. Talk to sales to discuss options.
