Cayman Chemical Cysteinyl Leukotriene ELISA Kit

Leukotrienes (LTs) are a group of acute inflammatory mediators derived from arachidonic acid via the 5-lipoxygenase (5-LO) pathway in leukocytes. LTC₄, LTD₄ and LTE₄ are collectively referred to as cysteinyl leukotrienes (CysLTs). LTC₄ and LTD₄ are potent mediators of asthma and hypersensitivity. They induce bronchoconstriction, increase microvascular permeability and are vasoconstrictors of coronary arteries. The biological activity of LTE₄ is much lower in most systems studied, but its presence reflects the prior existence of LTC₄ and LTD₄.

Cayman Chemical’s Cysteinyl Leukotriene ELISA Kit is a competitive assay based on a proprietary high-affinity monoclonal antibody that can be used for quantification of CysLT in urine and other sample matrices. The assay has a range from 8.6–2500 pg/mL and a sensitivity (80% B/B₀) of approximately 40.5 pg/mL.
