Human Leukotriene C4 (LT-C4) ELISA Kit,Abbkine,KTE61768
• Do not mix components from different kit lots or use reagents beyond the kit expiration date.• Allow all reagents to warm to room temperature for at least 30 minutes before opening.• Pre-rinse the pipet tip with reagent, use fresh pipet tips for each sample, standard and reagent to avoid contamination. • Unused wells must be kept desiccated at 4 °C in the sealed bag provided.• Mix Thoroughly is very important for the result. It is recommended using low frequency oscillator or slight hand shaking every 10 minutes.• It is recommended that all samples and standards be assayed in duplicate or triplicate.

Scientific Background
Leukotriene C4 is a leukotriene. Leukotrienes (LTs) are synthesized from membrane derived arachidonic acid. Downstream of 5-lipoxygenase in the arachidonic acid cascade, leukotriene C4 synthase (LTC4S)catalyses the conjugation of leukotriene A4 (LTA4)with reduced glutathione to form LTC4, then LTC4 convert to active metabolites LTD4 and LTE4. LTC4,LTD4 and LTE4, which are called cysteinyl leukotrienes (CysLTs), are potent proinflammatory mediators of asthma. There is a polymorphism of adenine (A) to cytosine (C)transversion at -444 locus in the promoter region of the LTC4S gene, A-444C.1 This allelic variant results in an extra recognition site for the Ap-2 transcription factor and is associated with an increased LTC4S transcription rate. 2 Some studies in other countries suggest that LTC4S A-444C polymorphism is associated with asthmatic severity and clinical response to leukotriene receptor antagonist.3-8
