That >99.9% HPLC purity isn’t just a number on a sheet — it means you're working with a peptide that’s been run through GMP guidelines and verified by mass spec, so batch-to-batch variability is basically gone, which matters when you're titrating doses in sensitive assays.
The molecular weight sits at 4234.6 g/mol, CAS 2381089-83-2, and formula C184H282N50O68 tells you this is a hefty peptide — solubility in water or buffer solutions is straightforward, but we usually recommend buffer over water for long-term stability in solution (we've seen precip drops after 48 hours in plain water).
You get it as a white to off- in 1mg, 5mg, or 10mg vials, or bulk if you’ve got a big study brewing — but it’s non-sterile research grade, so if you need sterile preparations for anything, this isn’t your tool; it’s meant for lab reconstitution and assay work only.
Store it at -20°C in a dry environment, and teh shelf life stretches out to 24 months or so under those conditions — one thing buyers don’t always think about is that humidity kills this powder faster than temperture swings, so seal the vial right after use.
Lead time is typically 10-14 business days, but we do keep stock on most vial sizes, so it’s usually quicker — every batch ships with COA and HPLC data, though confirm with us on large MOQs since bulk packaing can shift logistics.
Sure, we don't have a strict MOQ here. You can start with as little as a single 1mg vial to run your tests before scaling up.
Standard orders ship within 2-3 business days. For custom bulk packaging, lead time is about 5-7 days, depending on your volume.
Yes, every batch comes with a COA and both HPLC and MS reports. We include them with the shipment so you can verify the purity and identity yourself.
After opening, keep it sealed at -20°C and avoid moisture. A short temperature spike during transit is fine as long as it's not repeated—just store it properly upon arrival to maintain stability.
We can do custom vial sizes like 2mg or 20mg, as well as bulk containers. However, this is research grade and non-sterile—sterile filtration would need to be done in your lab before use.
