We've shipped quite a bit of this to labs looking at neurodegenerative pathways, and what it does is intriguing—it blocks amyloid-β-induced cell death at 10 μM in primary cortical neurons, which is pretty much the for initial screening in Alzheimer's models.
The sequence runs MAPRGFSCLLLLTSEIDLPVKRRA, molecular weight sits at 2687.1 g/mol, and it's soluble in water or saline so reconstitution is straightforward (usually 2-4 weeks lead time if we're out of stock).
Storage is critical here: keep it dry and cool at 2-8°C after reconstitution, and honestly, it's not great for in vivo work without further purification steps—most buyers go with teh 5mg vial size for cell culture assays where they need consistent dosing.
Purity is >99.0% by HPLC, and it's white to off-white powder typical of peptides in this range, though we usually have stock on the 5mg kits but confirm lead time if you need over 50 units or so.
The 5L drum is easier to handle for smaller batches, but for 5mg vials the packging is pretty standerd—no TDS or SDS included by default but our company can attach them on request.
One concrete detail: the powder tends to clump slightly if enviornment is humid, so keep the vial sealed until reconstitution.
We sell by the kit, so the MOQ is 1 kit, which contains 1 vial of 5mg. No minimum bulk order required.
Yes, we include a COA with each batch. It shows the HPLC purity results, molecular weight verification, and appearance — so you can see it's >99.0%.
For stock items, we usually ship within 1-2 business days after order confirmation. Domestic orders arrive in 3-5 days; international may take 7-14 depending on customs.
Yes, it's lyophilized white powder. Just add sterile water or saline to your desired concentration — it's soluble in both. Once reconstituted, store it at 2-8°C.
We can do custom labels for bulk orders — just let us know your requirements. For single kits, we keep standard vials to maintain integrity and traceability.
Naturally, I was initially quite apprehensive about ordering such a specialized research compound from an overseas supplier. However, my experience with SJ Peptides has been overwhelmingly positive across several key areas. The logistics and shipping process were handled with remarkable efficiency. I received a detailed tracking notification shortly after my order was confirmed, and the package arrived well within the estimated timeframe. It was securely and discreetly packaged, which is always a primary concern for items of this nature.

The vials were sealed perfectly, and all accompanying literature was clear and professional. This attention to detail in presentation strongly suggests a commitment to high standards in their manufacturing and handling processes. Most impressively, the customer service team was exceptionally responsive and knowledgeable. I had a few pre-purchase inquiries regarding shipping protocols, and they provided thorough, courteous, and prompt replies that addressed all my concerns. This level of service instilled a great deal of confidence. While I cannot comment on the specific application or biochemical parameters of the peptide itself, as that is a matter for controlled laboratory analysis, I can confidently state that the transactional and service aspects of dealing with SJ Peptides were flawless. The combination of reliable logistics, professional presentation, and outstanding support makes them a supplier I would not hesitate to use again for future research needs. The entire process, from order placement to delivery, was seamless and stress-free.
