High Purity 99.0% Salmon Calcitonin Acetate Peptide Powder for Research Use

Teh 99.0% purity floor is the first thing that stood out, and for a 32-amino acid peptide like this, that’s actually tighter than what a lot of suppilers push out — we’ve had batches from others that barely hit 98.5% on the HPLC.

It’s a synthetic polypeptide, molecular weight of 3431.85 g/mol, and we usually have stock of the, but confirm lead time if you need more than 100mg at once (check lead time — 2-3 weeks typically).

What it does is bind to calcitonin receptors, and researchers here use it for calcium metabolism studies, not for anything in vivo obviously — it’s strictly research grade, so don’t try to use it for anything clinical or diagnostic.

The solubility is slightly soluble in water, which basically means you’ll want to reconstitute it in a dilute acetic acid solution or something similar, and then store it at 2-8°C — the lyophilized form is stable enough at room temp for a few days or so, but after reconstitution, it degrades fast.

Also, the CAS is 47931-85-1, and the sequence has that disulfide bridge between Cys1 and Cys7, which is a detail most buyers don’t think to ask about but matters for handling — don’t vortex it aggressively or you’ll shear peptide.

3mg or 5mg vials depending on your batch, and the COA comes with every order — we’ve had zero purity complaints in the last 18 months, so it’s pretty much a standdard choice now.
