We're looking at a lyophilized GLP-1 analog, oral semaglutide, with a molecular weight just over 4113 g/mol and purity ≥99% by HPLC — pretty much teh standdard for in vivo work, but you'll want to verify solubility in your buffer since it's listed as 'to be determined' for water.
Most buyers go with the 5mg or 10mg vials for dose-response studies, and we usually have stock of both, but confirm lead time if you need the 15mg size (typically ships in 20 days or so).
It's not suited for anything beyond research use only, so don't expect to use this for formulation or clinical work without additonal purification steps, and the -20°C storage condition is non-negotiable for long-term stability.
What it does is provide a consistent starting materail for mechanisms involving the GLP-1 receptor, and the COA on each batch gives you the HPLC trace and purity spec — better than reagent grade for this type of assay.
powder is white and lyophilized, so reconstitution is straightforward, but one thing you might not think to ask is that the shelf life exceeds 2 years only if you never freeze-thaw and keep it at -20°C.
