General description

Picrylsulfonic acid solution is a hapten, which can bind to tissue proteins and turn into an antigen. This leads to several immunologic responses. Colitis induced by a 2,4,6-trinitrobenzene sulfonic acid (TNBS) is a type of delayed hypersensitivity reaction to haptenized proteins. Leukotriene B4 (LTB4) and the monhydroxyl fatty acids 5-hydroxyeicosatetraenoic acid (5-HETE), 12-HETE, and 15-HETE are the major inflammatory mediators involved in this TNBS-induced colitis. Ethanol when used in high concentration act as a vehicle for the TNBS administration.

Application

Hydrophilic modifying reagent. Derivatives with amino compounds can be regenerated with hydrazine.
Picrylsulfonic acid solution has been used:
  • to assess the efficiency of carboxymethyl lysine (CML) modifications of exposed primary amines
  • to incubate zona intact bovine embryos for the differential staining of blastocysts
  • to induce irritable bowel syndrome (IBS) in mice and to study its effects on Clostridium butyricum

Aberrant neutrophil extracellular trap (NET) formation and the loss of barrier integrity in inflamed intestinal tissues have long been associated with inflammatory bowel disease (IBD). However, whether NETs alter intestinal epithelium permeability during colitis remains elusive. Here, we demonstrated that
