Leukotrienes (LTs) are a group of acute inflammatory mediators derived from arachidonic acid in eosinophils, mast cells, and macrophages. Their biosynthesis proceeds via the 5-lipoxygenase (5-LO) pathway in which 5-LO converts arachidonic acid into LTA4 with 5(S)-HpETE as an intermediate. The conjugation of glutathione to LTA4 results in the formation of LTC4, which is then rapidly metabolized to LTD4 and LTE4. This metabolism is essentially complete within 10 minutes in the human lung. Cayman’s LTC4 ELISA Kit is a competitive assay that can be used for quantification of LTC4 in culture media and other sample matrices. The assay has a range from 17.1-5,000 pg/ml and a sensitivity (80% B/B0) value of approximately 40 pg/ml.

Leukotriene E4 (LTE4) is a product of the 5-lipoxygenase (5-LO) pathway in activated mast cells, eosinophils, and monocytes. LTA4, the primary 5-LO metabolite, is rapidly converted to LTC4 and sequentially to LTD4 and LTE4. While plasma levels of LTC4 are virtually undetectable, exogenously administered LTC4 is recovered in the urine as LTE4 (5-13%) and two prominent oxidized metabolites resulting from several cycles of β-oxidation. Cayman’s LTE4 ELISA Kit is a competitive assay developed for the measurement of LTE4 from urine without a purification step. The assay has a range of 7.8-1,000 pg/ml and a sensitivity (80% B/B0) of approximately 25 pg/ml. This “dilute and go” format has been used successfully to demonstrate significant and reproducible changes in LTE4 levels in the urine of asthmatic patients after antigen challenge. If your samples require additional purification prior to analysis, Cayman’s Cysteinyl Leukotriene Affinity Sorbent (Item No. 400396) can be used for this purpose.

Leukotriene E4-d5 (LTE4-d5) is intended for use as an internal standard for the quantification of LTE4 by GC- or LC-mass spectrometry. LTE4 is produced by the action of dipeptidase on LTD4, leaving only the cysteinyl group still attached to the fatty acid backbone.{2236} It is one of the constituents of slow-reacting substance of anaphylaxis (SRS-A).{394} LTE4 is considerably less active (8 to 12-fold) than LTC4 in the biological activities characteristic of cysteinyl leukotrienes.{2236,396} Unlike LTC4 and LTD4, LTE4 accumulates in both plasma and urine. Therefore, urinary excretion of LTE4 is most often used as an indicator of asthma.{1815,865,2064} In humans, basal levels of LTE4 range from 1-100 pg/mg creatinine. In asthmatic patients, urinary LTE4 levels increase to 80-1,000 pg/mg creatinine.{865} LTE4-d5 MaxSpec® standard is a quantitative grade standard of LTE4-d5 (Item No. 10007858) that has been prepared specifically for mass spectrometry or any application where quantitative reproducibility is required. The solution has been prepared gravimetrically and is supplied in a deactivated glass ampule sealed under argon. The concentration was verified by comparison to an independently prepared calibration standard. This LTE4-d5 MaxSpec® standard is guaranteed to meet identity, purity, stability, and concentration specifications and is provided with a batch-specific certificate of analysis. Ongoing stability testing is performed to ensure the concentration remains accurate throughout the shelf life of the product. Note: The amount of solution added to the vial is in excess of the listed amount. Therefore, it is necessary to accurately measure volumes for preparation of calibration standards. Follow recommended storage and handling conditions to maintain product quality.
