Custom TB-500 Production: High-Quality Peptide with CAS 885340-08-9

When cells need to repair or remodel their cytoskeleton—basically the internal structure that gives them shape and mobility—the process is slow and inefficient without the right signals, and that's where a synthetic analog like this one comes into play, mimicking naturally occurring peptides involved in tissue regeneration and cell migration.

It binds to actin and promotes its polymerization, which is critical for wound healing and angiogenesis in research models, though it's definetly not suited for human use or clinical applicaion just because of that it's high purity.

We're looking at 99% purity by HPLC and food-grade classification, so it's clean enough for relaible cell culture or in vivo studies where contamination would throw off results; CAS 885340-08-9 is identifier and the sequence is Ac-Leu-Lys-Lys-Thr-Glu-Thr-Gln-OH, five residues or so depending on how you count it, 7 amino acids exactly.

A detail most buyers don't think to ask: it's hygroscopic, so store it desiccated at -20°C once reconstituted, or it'll degrade faster than you'd expect—usually within 2-3 days in solution.

We typically have it in stock as a lyophilized powder in 5mg or 10mg vials (check the MOQ if you need custom gram amounts), and lead time is usually 3-5 business days for standerd orders, though custom sequences can run 2-4 weeks.

Anyway, most research teams I've talked to prefer this over cheaper alternatives because the tighter tolerance on end-group modifications actually matters when you're looking at peptide stability in serum.
