Application
Prostaglandin B2 has been used as an internal standard in high-performance liquid chromatography (HPLC).
Biochem/physiol Actions
Prostaglandin B2 (PGB2) is an eicosanoid and a lipid mediator. It is synthesized by the dehydration of PGE2. It is a primary prostaglandin associated with the osteoblasts and may induce pulmonary hypertension. PGB2 is also reported to inhibit glucagon stimulated glycogenolysis and forskolin-stimulated adenylate cyclase activity in plasma membranes.
Physical form
Prostaglandin B2 is supplied as a solution in methyl acetate
Preparation Note
PGB2 is provided as a solution in methyl acetate. To change the solvent, evaporate the methyl acetate under a gentle stream of nitrogen and immediately add the solvent of choice. PGB2, purged with an inert gas, is soluble in ethanol at ~100 mg/mL, DMSO at ~50 mg/mL and in dimethyl formamide at ~ 75 mg/mL.

In the brain, approximately 90% of oxylipins are esterified to lipids. However, the significance of this esterification process is not known. In the present study, we (1) validated an aminopropyl solid phase extraction (SPE) method for separating esterified lipids using

An automated on-line sampling method was developed using microdialysis as the simultaneous sampling and sample pre-treatment technique. The extraction fraction values of microdialysis probes sampling different eicosanoids were investigated. The impact of cyclodextrins in the perfusion liquid used for sampling

We describe prostaglandin (PG) biosynthesis by isolated midgut preparations from tobacco hornworms, Manduca sexta. Microsomal-enriched midgut preparations yielded four PGs, PGA/B(2), PGD(2), PGE(2) and PGF(2alpha), all of which were confirmed by analysis on gas chromatography--mass spectrometry (GC--MS).
