We've been moving a lot of this lately, and it's the 99% or better lyophilized powder that lands at roughly 4113.6 g/mol — the GLP-1 receptor agonist mechanism for appetite regulation and glucose-dependent insulin secretion is what drives the interest in weight management research, though it's not suited for in vivo work without proper reconstitution protocols.
Most buyers go with the 10mg vial for longer studies, but the 1mg or 2mg options are better if you're doing preliminary binding assays or dose-response work — basically, teh 5mg strikes a nice balance for typical in vitro setups, and it's soluble in DMSO or sterile water depending on your buffer system.
The CAS is 2023788-19-2, and you'll want to store it at -20°C protected form light — we usually have stock, but confirm lead time if you're ordering more than 50 units or so, as the 24-month shelf life is only good if you don't leave it on the bench.
Also, one thing that catches people: the powder looks white and fluffy straight out of the freezer, but it can clump if you don't let the vial warm to room tempearture before opening — that's just lyophilized peptide behavior, not a purity issue, and COA from HPLC will confirm the ≥99% spec.
5, we use it in our own lab for receptor activation studies, and the pharmaceutical grade means tighter tolerance than some research-grade batches, but honestly, for simple reconstitution work, any grade will do — just don't expect it to dissolve instantly in water without gentle vortexing.
1mg, 2mg, 5mg, or 10mg lyophilized vials are the standerd packging, and the MOQ is typically one vial per size — our company can ship within 20 days or so, but check if you need expedited handling.
