Leptin — frequently asked

What is leptin?
Leptin is a small protein hormone encoded by the LEP gene and produced largely by adipose tissue. It adopts a four-helix bundle fold and is reported to signal through the leptin receptor, activating JAK and STAT pathways in responsive cells.
Why is leptin studied in research settings?
Leptin is widely used to investigate energy balance, adipose tissue biology and neuroendocrine signalling, and as a reference analyte in metabolic studies. Recombinant preparations also serve as positive controls and standards in receptor binding and cell-based assay development.
Which species forms are available?
Recombinant human, mouse and rat leptin are the most common catalog items, along with matched antibodies and kits. Sequence differences between species mean that a standard curve built with one species may not read another accurately, so matched reagents are preferred.
