Calibration Range

2–250 pg/ml

Limit of Detection

The Limit of Determination, calculated as the concentration of unacylated ghrelin corresponding to the NSB average (n = 8) plus three standard deviations is 0.2 pg/ml and 0.6 pg/ml for long and short first incubation period, respectively.

Intra-assay (Within-Run)

CV = 6.3% (20h at +4°C)
CV = 6.9% (3h at RT)

Inter-assay (Run-to-Run)

CV = 7.0% (20h at +4°C)
CV = 7.2% (3h at RT)

Spiking Recovery

87.6% (20h at +4°C)
86.3% (3h at RT)

Dilution Linearity




  • The kit measures plasma unacylated ghrelin.
  • Quality controls are human-plasma based.

Ghrelin, an endogenous ligand for the growth hormone secretagogue receptor, is synthesized principally in the stomach. It stimulates food intake and transduces signals to hypothalamic regulatory nuclei that controls energy homeostasis. The peptide consists of 28 amino acids, with a n-octanoylation of the serine-3 residue, which is necessary for the biological activity mentioned below. Ghrelin is present in the peripheral circulation under two forms: acylated and unacylated.
