Full Name: CGRP ELISA Kit (Calcitonin Gene Related Peptide)

Sample Type: Serum, Tissue Homogenates, Biological Fluids, Plasma
Sensitivity: 9.375 pg/ml


A family of peptides, including calcitonin, calcitonin receptor stimulating peptide, adrenomedullin, adrenomedullin 2 (intermedin), and amylin, includes calcitonin gene-related peptide (CGRP). It is formed from thyroid C cells and it is stored and released into the nervous system. The human peptide can be either alpha-CGRP or beta-CGRP. The alpha peptide is 37 amino acids neuropeptide and this is produce from alternative splicing of calcitonin/CGRP gene. However, less is known about the beta-CGRP apart from the fact that it is located to a separate gene to the alpha and it differs by three amino acids. The presence of it and its receptors in the brain may be an indicator for certain neuropathic pain conditions including chronic neuropathic pain which is often referred to as reflex sympathetic dystrophy.

The central and peripheral neurons are responsible for producing CGRP. It performs as a vasodilating peptide and aids in the transmission of nociception. It is derived from motor neuron body cells that have been synthesised within the spinal cord ventral horn. It also found to display effects on the homeostasis of calcium. It functions as an appetite suppressant and aids the secretion of gastric acid. Other roles include; increasing heart rate, releasing of pituitary hormones and temperature homeostasis.

CGRP is not only released in the central and peripheral neurons, but it also exists at high levels in the hypothalamus. It has been discovered to have an impact on food consumption and weight. There are several “work functions” including; decreasing pain perception, increasing heart rate and blood pressure, increasing gastric acid secretion, releasing of pituitary hormones and temperature homeostasis. The hypothalamus region where hunger and satiety signals are produced contains the receptors. NPY is also found in this area, suggesting that it may be involved in regulating appetite and food intake.


Human CGRP ELISA kit can be used to measure amounts of calcitonin gene related peptide (CGRP) present is human serum, tissue homogenates, plasma and other biological fluids.

I am a first time user and found that your instruction manual was very easy to follow. The insulin ELISA assay performed well and I was happy with the results that were generated.

J. Thomas
Senior Technician / Addenbrooke’s Hospital

I carried out a pilot study comparing the performance of many ELISA assay's from different suppliers and found your kits to be one of the better performers. We observed good linearity and tight replicates.
