TB-500 Peptide Powder CAS 885340-08-9 | 99% Purity Factory Supply

You're probably sourcing this for cell migration or actin polymerization studies, and difference between 98% and 99% purity actually shows up in your —we've seen labs struggle with inconsistent batches and that's basically what we're eliminating.

CAS 885340-08-9, molecular weight 889.01, it's lyophilized as a white powder so reconstitution is straightforward in water or saline. 99% purity means less cleanup before you can trust your results, though the 5L drum is easier to handle if you're running a large study.

Store it at -20°C or below, and the materail won't degrade for several months—roughly 12 months if sealed properly. Most buyers go with the 10mg vial per batch for smaller assays, but our company can do custom packaing (usually 2-4 weeks). Check lead time if you need more than 50 units or so.

What it's not suited for is anything involving long-term ambient storage without desiccant; moisture will wreck the peptide's integrity quickly. Ac-Leu-Lys-Lys-Thr-Glu-Thr-Gln-OH is the sequence, and keeping it frozen is non-negotiable for that actin-binding property to hold up.

Also, and this is something many buyers forget: the powder is hygroscopic, so when you open it, you're better off bringing it to room temperture first in a sealed bag. One concrete detail—we've had fewer complaints with teh 25mg vials for daily microdosing protocols because they minimize freeze-thaw cycles.
