Gastrin-releasing peptide (GRP), is a 27-amino acid neuropeptide. Gastrin-releasing peptide stimulates the release of Gastrin from the G cells of the stomach, and regulates gastric acid secretion and enteric motor function. Gastrin-releasing peptide is also an important growth-modulating factor in developing lung epithelium. It has been used as a tumor marker in the diagnosis of small-cell lung carcinoma, since it is known to be produced by these cancer cells. GRP is also involved in the biology of the circadian system, playing a role in the signaling of light to the master circadian oscillator in the suprachiasmatic nuclei of the hypothalamus. Furthermore, GRP seems to mediate certain aspects of stress.

• Strip plates and additional reagents allow for use in multiple experiments
• Quantitative protein detection
• Establishes normal range
• The best products for confirmation of antibody array data

Standard, biotinylated peptide, and positive control should be stored at -20°C after arrival. Avoid multiple freeze-thaws. The remaining kit components may be stored at 4°C. Opened microplate wells and antibody (Item N) may be stored for up to 1 month at 2° to 8°C. Return unused wells to the pouch containing desiccant pack and reseal along entire edge.
