Leptin research reagents
Leptin is a 146-residue adipocyte hormone, 167 with its signal peptide, folded like a four-helix cytokine, signalling through the long form of the leptin receptor to report fat mass to the hypothalamus. Diet-induced obesity is characterised by high leptin with blunted response, so the interesting measurements are usually receptor-side. Because the folded protein is held by a disulphide bond, defined fragment peptides are used as immunogens and standards, and receptor-domain peptides to raise antibodies against ObR.
This page lists all 60 Leptin entries in the reference catalog — 17 labeled peptides, 14 labeled antibodies, 12 antibodies, 11 peptides and 6 assay kits, across mouse, human and rat sequences. Reference prices run $161 – $1,159; everything is available to order by catalog number.

Ordering Leptin 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.
Leptin 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.
