Product Description:
Pepsinogen is an inactive precursor of pepsin in gastric fluid, which can be immunologically divided into two types: pepsinogen I(PGI) and pepsinogen II(PGII). PGI is secreted by gastric fundus gland, PGII is secreted by gastric main cells and mucous cells, pyloric gland in gastric antrum and Brunner gland in proximal duodenal mucosa. The physiological level of serum PGI/PGII is about 4:1. PGI/PGII decreased linearly with the increase of the severity of systolic gastritis. The ratio of moderate to severe atrophic gastritis was <2.53.
The Clinical Significance
Assessment of Gastric Mucosal Function: Levels of Pepsinogen I can reflect the number and functional status of the chief cells in the gastric mucosa. A decrease in its concentration may indicate atrophy of the gastric mucosa or reduced gastric acid secretion, possibly associated with chronic atrophic gastritis, gastric cancer, etc
Test Principle
Double antibody sandwich method was used in the kit. The detection principle is: the sample to be tested, R1 reagent, R2 reagent and M reagent are mixed for incubation, and the fluorescein (FITC) labeled PGII antibody 1 in R1 reagent and the alkaline phosphatase (ALP) labeled PGII antibody 2 in R2 reagent are combined with the PGII antigen molecules in the sample to form an immune complex. The immune complex is further captured by anti-FITC antibodies coupled to the surface of the magnetic particle and adsorbed to the surface of the magnetic particle. After washing, the unbound material was removed and the luminescent substrate was added, ALP catalyzed the luminescence of the substrate, and the relative luminescence intensity (RLU) was determined.
