If they're running thrombin inhibition assays or studying clot formation in real time, this is what they'd reach for — it reversibly binds the active site and stops fibrinogen conversion, which is the whole point in cardiovascular work.
We're seeing it at ≥99% by HPLC, that's slightly soluble in water, and the molecular weight comes in at 2295.32 g/mol — most buyers go with the 10mg vial for initial, but our company can do 50mg or 100mg (check lead time on larger sizes).
The sequence is 20 amino acids long — D-Phe-Pro-Arg-Pro-Gly-Gly-Gly-Gly-Asn-Gly-Asp-Phe-Glu-Glu-Ile-Pro-Glu-Glu-Tyr-Leu-OH — and it's a trifluoroacetate salt, which basically means it's pretty stable at 2-8°C after reconstitution, but don't freeze it.
Actually, one thing people miss is that it's not great for oral dosing studies — it's strictly for in vitro or IV work in lab models, so if your buyer's planning gavage experiments, this isn't right fit.
We usually have stock on teh 99% purity grade, roughly 20 days or so for custom batch sizes, and the COA covers HPLC purity and peptide content — no need to chase that seperately.
That indicates the peptide is complexed with trifluoroacetic acid (TFA), which is common for peptide salts. The 'x' means the exact number of TFA molecules per peptide varies slightly between batches, but it doesn't affect the ≥99% purity or activity.
It's slightly soluble in water but dissolves fine in buffers like PBS or saline for your assays. We recommend pre-wetting with a small amount of DMSO or acetic acid if you need higher concentrations, then diluting into your buffer.
Our MOQ is typically 100 mg for this research-grade peptide, but we can accommodate smaller custom orders if you're just starting a study. Just reach out and we'll see what works.
Yes, every shipment includes a COA with purity by HPLC, mass spec confirmation, and appearance details. We can also provide a full analytical package if needed.
Store the dry powder at -20°C or below for long-term stability. Once reconstituted in buffer, keep it at 2-8°C and use within a week to avoid degradation — avoid repeated freeze-thaw cycles.
