title: The use of 12-hydroxyheptadecatrienoic acid (HHT) as an HPLC/spectrophotometric marker for cyclooxygenase pathway activity in resident rat peritoneal cells.
abstract: 12-Hydroxyheptadecatrienoic acid (HHT), a UV chromophore, has been used to assess cyclooxygenase (CO) pathway metabolism of arachidonic acid (AA) by rat peritoneal cells. Simultaneous monitoring at 235 and 280 nm after HPLC permits the measurement of both CO and 5-lipoxygenase (5-LO) pathway fluxes in a single system.
