It's not sterile, so if your protocol requires that, you'll need to filter it yourself — most labs already do that step anyway, and the 98%+ purity means you're starting with a clean batch that's better than reagent grade for this.

We usually have stock for custom quantities, but confirm lead time because bulk orders (100mg or more) can take 20 days or so depending on how busy the synthesis line is.

Basically, you're getting a white powder that's been HPLC-tested, stored at -20°C form day one, and shipped under standdard lab conditions — no cold chain surprises, and teh COA is avaliable upon request if you want to see exact purity number.
Most researchers go with the 10mg vial option for initial work, but we've also supplied 50mg and 500mg for larger studies — the molecular weight varies by sequence, so check the batch sheet for your exact calculation.

What it does is hold up well for about 12 months if you keep it at -20°C, and it's soluble in water or specific buffers; one thing buyers don't always ask is that it's not ideal for long-term room temp use, so plan your aliquots ahead.
