Cleavage Reaction Lateral Flow Assays for Salivary Pepsin Measurement Using a Pepsin-Susceptible Peptide Substrate

Chemosensors
In this study, we introduce a novel cleavage reaction lateral flow assay (LFA) based on pepsin activity against a pepsin-susceptible peptide (PSP) substrate to detect salivary pepsin.

Pepsin D. A minor component of commercial pepsin preparations [PDF]

Biochemical Journal, 1967
Methods are described for the isolation and purification of pepsin D, an enzyme which accounts for about 10% of the enzymic activity in commercial preparations of pepsin. Pepsin D is similar to pepsin in having a molecular weight of about 35000, the same C-terminal amino acid sequence, and an N-terminal isoleucine residue.

Safety evaluation of the food enzyme containing chymosin and pepsin from the abomasum of calves and cows

EFSA Journal, 2021
The food enzyme containing chymosin (EC 3.4.23.4) and pepsin (EC 3.4.23.1) is produced from the abomasum of Bos taurus purchased from different rennet manufacturers by Laboratorios Arroyo S.A. The food enzyme is intended to be used in milk processing for

Efficacy of dietary modifications and mucosal protectors in the treatment of laryngopharyngeal reflux: a multicenter study

Frontiers in Medicine
BackgroundLaryngopharyngeal reflux (LPR) is defined as an extraesophageal reflux of gastroduodenal contents to the laryngopharynx, affecting the upper aerodigestive tract. There is currently no standardized treatment protocol for LPR.

Immunoserologic Pepsin Detection in The Saliva as a Non-Invasive Rapid Diagnostic Test for Laryngopharyngeal Reflux

Balkan Medical Journal, 2015
Background: The most common tool for the diagnosis of laryngopharyngeal reflux (LPR) is still 24-hours esophageal pH monitoring; there is lack of non-invasive, less expensive and accurate diagnostic tools for this frequent disease.
