Orphanin FQ research reagents
Orphanin FQ — equally known as nociceptin — is the 17-residue endogenous ligand of the NOP receptor, the fourth opioid receptor, and was named twice because two groups identified it simultaneously. It resembles dynorphin A but begins with Phe rather than Tyr, so it does not act at the classical μ, δ and κ receptors. It is studied in nociception, anxiety, reward and feeding, and the (1-13) amide fragment and substituted analogues are used to probe NOP selectivity.
This page lists all 46 Orphanin FQ entries in the reference catalog — 22 peptides, 12 labeled peptides, 6 assay kits, 4 antibodies and 2 labeled antibodies, across human, mouse, ox, rat and bovine sequences. Reference prices run $88 – $1,159; everything is available to order by catalog number.

Ordering Orphanin FQ reference material
Every row above is a reference listing, not a stocked storefront line: the catalog number is the reference we quote against, and the price shown is the reference price for the size in the detail column. Send the catalog number and we will confirm current availability, lead time and the exact size before anything is ordered. If a sequence, species or label you need is not in this family, ask — our reference network is wider than this catalog.
Orphanin FQ material listed here is laboratory research material. It is not a drug, supplement or consumer product, and nothing on this page describes a therapeutic use.
