So one of our clients in the US has their lab actually using this to run binding assays on GLP-1 receptor variants in primary cell cultures—basically they're looking at how modifications in the peptide backbone affect downstream cAMP signaling in pancreatic islets, which is pretty specific work that demands consistent purity across batches.
It's ≥99% by HPLC, and we get the MW verified by MS on every lot, but what matters more for import is that our company can supply the full COA and a letter of intent for customs—especially for EU shipments where they're stricter about declaring research-only status—and we usually have stock in 20 days or so from order.
24 months stability when you keep it at -20°C in a dry enviornment, though if you're in a humid climate you'll want to use desiccant packs in the shippng container (we can include those on request). The lyophilized format means you reconstitute in sterile water or buffer, and the sealed vials with safety caps are standard for most research biotechs we ship to.
One thing this isn't suited for—and I should flag this—is any kind of in vivo work without further formulation, because teh solubility profile is optimized for buffer systems rather than saline or oil-based vehicles, and MS characterization doesn't cover endotoxin levels. Most buyers go with the 5mg or 10mg vial sizes depending on their assay throughput.
Also, for UK labs post-Brexit, we've got the paperwork sorted for HMRC classification as a research chemicla, not a pharmaceutical intermediate—that distinction saves you a headache at customs and keeps the duty rate lower, but confirm your local import regs because they vary by country in the EU.
Our MOQ for this compound is typically 10 vials per order. We can discuss smaller trial quantities for serious research institutions, but standard orders start at 10 units.
Standard lead time is 7-10 business days after payment confirmation. Expedited processing is available for bulk orders, just let us know your timeline.
Yes, we include a Certificate of Analysis with each batch that shows the ≥99% purity verified by HPLC and the molecular weight confirmed by mass spectrometry. These are standard with every shipment.
We strongly recommend keeping it at -20°C in a dry environment for long-term stability. It can handle short-term exposure (a few hours) at room temperature during reconstitution, but prolonged storage above -20°C will degrade the product.
Yes, we can customize vial labeling and packaging configurations for bulk orders. Just specify your requirements, and we'll adjust the sealed vials with safety caps accordingly.
