Revvity, 64LB4PEH, HTRF LTB4 Detection Kit, 10,000 Assay Points

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. HTRF assays offer many advantages over other technologies: Homogeneous add-and-read format No wash steps Low background Straightforward miniaturization from 96- or 384-well microplates to high density assay formats such as 384-well low volume and 1536-well plates Stable signal, providing flexibility in time of readout or size of assays
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. Assay protocol The LTB4 assay features a streamlined protocol with only 1 incubation step after sample and LTB4 detection reagents dispensing. This protocol requires a single two-hour incubation period at RT.
