A custmer doing dose-response work in metabolic receptor assays will reconstitute this into solution and aliquot it for serial dilutions, and the white lyophilized cake holds up well at -20°C for about 18 months before we’d recommend fresh stock.
Purity comes in above 99% by HPLC and impurity levels stay at 0.5% or less—better than reagent grade for this kind of binding work, though you’ll still want to run your own QC if you’re pushing sub-nanomolar concentrations.
We usually have 1g ready to ship, but lead times for custom synthesis can run 3-4 weeks (check on that before ordering), and MOQ is pretty low so you’re not locking in a huge batch for pilot studies.
Molecular weight is sequence-dependent so you’ll need to confirm the exact peptide chain before doing molarity calculations—it’s not a fixed number like some small molecules, and the COA includes MS data to verify it.
Packaing is flexible enough that most buyers go with 10mg vials for lab use, but bulk powder in bottles works fine if you’re doing large-scale screening, just keep it dry and away form light.
It’s not suited for anything beyond research—no in vivo work without your own ethics clearance, and teh solubility in water is fine but buffers at pH 7.4 usually work better for avoiding aggregation during reconstitution.
The MOQ is set at 1g. We don't offer smaller trial sizes below that, but 1g already gives you enough for solid testing. Larger bulk quantities are also available if you need more.
Every batch comes with a Certificate of Analysis (COA) that shows purity >99%, impurity levels ≤0.5%, and HPLC, MS, and amino acid analysis results. You'll get full traceability on the specs.
Store it at -20°C in a dry environment, and keep it sealed to avoid moisture. If you follow that, it stays stable for up to 24 months from production.
Yes, packaging is fully customizable—vials, bottles, or bulk containers. Just let us know your preferred format and quantity per unit when you order.
Lead time depends on the quantity and any custom modifications. For standard orders it usually ships within 1-2 weeks. Custom synthesis may take a bit longer—we'll confirm the timeline once we review your request.
