Intra-assay Precision (Precision within an assay): CV%<8%      
Three samples of known concentration were tested twenty times on one plate to assess.  
Inter-assay Precision (Precision between assays): CV%<10%      
Three samples of known concentration were tested in twenty assays to assess.    
To assess the linearity of the assay, samples were spiked with high concentrations of rat gastrin in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

Target Background

(From Uniprot)
Gastrin stimulates the stomach mucosa to produce and secrete hydrochloric acid and the pancreas to secrete its digestive enzymes. It also stimulates smooth muscle contraction and increases blood circulation and water secretion in the stomach and intestine.
Gene References into Functions
  1. we examined the chronic effects of a GLP-1-gastrin dual agonist ZP3022 on glycemic control and beta cell dysfunction in overtly diabetic Zucker Diabetic Fatty PMID: 25849341
  2. treatment with gastrin, a CCK2R agonist, stimulated the secretion of GLP-1, and that this effect was likely due to increased expression of proglucagon and PCSK1 (also known as prohormone convertase 3 (PC3 gene)). PMID: 25601282
  3. The results suggested that clusterin may contribute to gastrin's growth-promoting effect on the oxyntic mucosa. PMID: 21995960
  4. plays a role in the development of gastric mucosa, ECL cells and A-like cells in newborn and young rats PMID: 12220729
  5. role in increasing expression of COX-2 mRNA and protein, the activity of the COX-2 promoter, and the release of prostaglandin E(2) PMID: 12239223
  6. High temperature can affect gastrin, somatostatin and motilin production in the gastric antral mucosa of rats with gastric ulcer. PMID: 12376287
  7. study demonstrates that gastrin enhances gastric mucosal integrity through cyclooxygenase-2 PMID: 12388195
  8. Data suggest that distention of isolated rat stomach stimulates somatostatin release via cholinergic and non-cholinergic TTX-insensitive pathways, and that these pathways are responsible for distention-induced inhibition of gastrin release. PMID: 12508367
  9. gastrin induces Akt through activation of CCKB receptors and of intracellular calcium-dependent, PKC-independent, pathways PMID: 15351698
  10. the role of JAK-dependent pathways in the regulation of E-cadherin-dependent cell-cell adhesion by gastrin PMID: 15530849
  11. gastrin- and PACAP-stimulated secretion of histamine and pancreastatin is inhibited by somatostatin, misoprostol and galanin in enterochromaffin-like cells PMID: 15935492
  12. hypogastrinemia and impaired enterochromaffin cell function in the oxyntic mucosa of the stomach might be partially responsible for the reduction in body weight that occurs after gastric bypass PMID: 16645284
  13. G cells are luminal sampling chemomechanosensory cells whose gastrin secretion is regulated by neural, hormonal, luminal, and mechanical factors through protein kinase A activation, cAMP signaling, and mitogen-activated protein kinase phosphorylation. PMID: 19208342
