The Leukotriene B4 kit is designed for the accurate quantification of LTB4.


LTB4 is a major leukotriene product that is enzymatically derived from the arachidonic acid cascade. LTB4 is synthesized by leukocytes via the 5-lipoxygenase pathway and mediates different leukocyte functions such as lysosomal enzyme release, adhesion, and aggregation of polymorphonuclear leukocytes. LTB4 has been described as a potent mediator of inflammatory diseases and immunoregulation. The LTB4 kit enables the monitoring of LTB4 produced by cells and can be used to study the LTA4-hydrolase.



Assay principle

The LTB4 kit is a competitive immunoassay for the measurement of LTB4 in a range of biological formats. The assay uses an Eu3+-Cryptate conjugated antibody specific to LTB4 and XL665 coupled LTB4. LTB4 in the sample competes with XL665-labelled LTB4 for binding to anti-LTB4 Eu Cryptate.
