Catalog Peptides for Research — Ready to Order, Verified on Arrival

Our catalog peptides are synthesized in batches, purified by reversed-phase HPLC, identity-checked by mass spectrometry, and lyophilized into sealed vials — so when your cell culture window opens or your assay plate is loaded, the product is already on your bench, not still on a reactor.

This page walks you through exactly how catalog ordering works: what you will find in the catalog, how to search and quote in bulk, what quality documents arrive with each shipment, and how we ship to your laboratory anywhere in the world.

What Is in the NovoPep Catalog

Our ready-to-order product families cover the reagents most labs reorder week after week:

•     Biologically active catalog peptides — including our dedicated Amyloid Beta peptides and RGD peptides collections for neuroscience and integrin research, plus a rotating list of popular research peptides.

•     The full catalog peptide library — hundreds of sequences across signaling, antimicrobial, hormone, and cosmetic-peptide categories, each listing purity grade, molecular weight, and CAS number.

•     Protected amino acids — Fmoc, Boc, and Z-protected amino acids plus specialty building blocks, in stock sizes that keep your own synthesis runs going without waiting on a new batch.

•     Linkers and resins — solid supports matched to the loading and cleavage chemistry your protocol demands.

Can't find your sequence? Everything we do not keep in stock can be made to order through our custom peptide synthesis service, with purities from crude to greater than 98 percent and turnaround on standard sequences of two to three weeks.

How to Order Catalog Products — Four Steps

1.    Search or upload. Browse product categories directly, or paste a list of CAS numbers and product codes into the batch search box — one entry per line — to check stock across the whole catalog in a single pass.

2.    Get a confirmed quote. Send your list to service@novopep.com. Our team replies within 2 to 24 hours with unit pricing, available purity grades, vial sizes, and lead time. Bulk and repeat-use discounts apply automatically at quoted volumes.

3.    Produce, fill, and document. Stocked items move to packaging immediately; larger quantities come off the next scheduled batch. Every order ships with its Certificate of Analysis: HPLC purity chromatogram, ESI-MS identity confirmation, net peptide content, batch number, and recommended storage conditions.

4.    Receive and reorder. Track your shipment door to door. Keep your account on file and reordering a validated item becomes a one-line message — same batch QC, same documentation, better pricing as volumes grow.

Quality You Can Audit, Vial by Vial

A catalog peptide is only as good as the paper trail behind it. Each NovoPep shipment is held to the same dual verification we apply to custom work: reversed-phase C18 HPLC at 220 nm quantifies purity by peak-area integration, and electrospray ionization mass spectrometry confirms observed molecular weight against the theoretical sequence — catching truncations and sequence errors before a vial ever leaves Shanghai. TFA-desalted and TFA-exchanged (HCl or acetate counterion) formats are available on request for cell-based assays and structural studies, consistent with the specifications described on our custom synthesis page.

Choose your purity grade to match the experiment: analytical-grade material for assay development, greater-than-95 percent preparations for bioactivity work, and greater-than-98 percent for demanding applications. Our Recommended Peptide Purity guide maps grades to use cases.

Bulk Orders and International Shipping, Built for Labs Abroad

NovoPep ships worldwide from our Shanghai facility, and export logistics for lyophilized peptides are part of the standard workflow, not an afterthought. Orders travel in stable freeze-dried form, packed for room-temperature transit on short legs and with cold-chain options for sensitive targets, with commercial invoices and documentation prepared to clear customs in the United States, the European Union, the United Kingdom, and most Asia-Pacific destinations.

Procurement teams order from us the way they order from any established supplier: consolidated lists, scheduled repeat deliveries, purchase-order invoicing, and volume pricing that holds quarter over quarter. Tell us your annual sequence list and we will build a stocking plan so the peptides you consume monthly never leave your team waiting.

Catalog Peptides or Custom Synthesis — Which Do You Need?

Order from the catalog when the sequence is standard, the purity grade is listed, and speed matters: stocked items ship in days, and batch search lets a whole requisition be checked at once. Go custom when your target carries a non-standard sequence, a label, a cyclization, a longer chain up to 160 residues, or a scale beyond catalog sizes — a custom synthesis quote costs nothing and arrives within a day. Many customers split the difference: catalog building blocks and resins for in-house chemistry, NovoPep custom synthesis for the hard sequences.

Frequently Asked Questions

How do I order catalog peptides from outside my country?

Email your list of catalog IDs or CAS numbers to service@novopep.com, or paste them into the batch search field on this page, one per line. You will receive a quote with shipping options to your address within 2 to 24 hours.

Are NovoPep catalog peptides lyophilized, and how should I store them?

Yes. Catalog peptides ship as sealed lyophilized powder. Store at 2 to 8 degrees Celsius with desiccant, keep vials sealed until use, and follow the storage notes printed on each Certificate of Analysis. Reconstitution guidance is available in our Reconstitution Procedure and Handling & Storage resources.

What documentation comes with a catalog order?

Every vial is backed by a Certificate of Analysis covering batch number, HPLC purity, mass spectrometry confirmation, net peptide content, and storage conditions. Raw chromatograms accompany the COA on request.

Do you offer discounts for bulk or recurring orders?

Yes. Quoted volumes unlock automatic price breaks, and standing repeat orders can be placed on a scheduled stocking plan. Mention your expected annual usage in the first inquiry and the quote will reflect it.

What if my peptide is not in the catalog?

Any catalog miss becomes a custom synthesis request. Send the sequence, desired purity, scale, and any modifications to service@novopep.com — acetylation and amidation are complimentary, and fluorescent (FAM, FITC, TAMRA) and isotope (N15, C13) labeling are available.

Search the catalog above, or send your list of CAS numbers and product codes to service@novopep.com / service@novopep.info. A NovoPep specialist will reply with pricing, stock status, and shipping lead time — usually within one business day.
