We're looking at the 10mg vials of TB-500, basically teh synthetic fragment of Thymosin Beta-4, and it's pretty much what most researchers in this space go for when studying tissue repair and inflammatory cascade—it's a 43-amino acid peptide analog with a CAS of 885340-08-9, but you probably already knew that.
Purity runs ≥99% by HPLC, and we generally have about 200 boxes or so in stock, though confirm lead time if you're ordering over 50 boxes since that affects our MOQ—it's a, soluble in both water and methanol, which makes reconstitution straightforward for most in vivo models.
What it does is promote actin sequestration and modulate cell migration, so you'll see it used in wound healing studies or cardiac ischemia work, but it's absolutely not suited for human consumption or any clinical applicaion—that's a firm line our company can't cross on this bulk order.
Storage is critical here: you'll need to keep it at -20°C, and we've had some buyers ask about room-temperature shipping, which is fine for transit (usually 2-4 days), but once it arrives, it's got a 24-month shelf life if you keep it frozen; the vials are packed at 10 per box, and each vial's a single-use 10mg dose, so plan your reconstitution volume accordingly—it's better than reagent grade for this specific peptide work.
One detail that might not be obvious: the powder can clump slightly if the desiccant pack is compromised during shiping, but that doesn't affect the purity—we test each batch with HPLC and provide a COA, though I'd recommend you run your own validation if you're doing sensitive kinetic studies.
Also, the molecular weight is 889.02 g/mol, and the formula is C38H68N10O14, which lines up well with the reference data form most peptide databases—anyway, for ordering, just specify the quantiy and we'll confirm the lead time, usually 10-14 business days for bulk.
For bulk orders, the MOQ is typically 10 boxes (100 vials). If you need less, we can discuss, but that's the standard for bulk pricing.
Lead time is usually 5-7 business days after payment confirmation for stock items. Custom orders may take 10-15 days.
Yes, we supply a CoA with every batch, confirming the ≥99% HPLC purity and other specs. Just request it with your order.
Store them at -20°C in a freezer, away from light and moisture. Once reconstituted, use immediately or keep refrigerated and use within a few days.
We can do custom labeling and packaging for bulk orders. Minimum for customization is typically 50 boxes, and we'll need to discuss specifics.
