Human Leukotriene A4 (LTA4)  ELISA Kit | KTE62713

Human Leukotriene A4 (LTA4)  ELISA Kit | KTE62713 | Gentaur UK, US & Europe Distribution

Application: This Human Leukotriene A4 (LTA4)  ELISA Kit employs a two-site sandwich ELISA to quantitate LTA4 in samples. An antibody specific for LTA4 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyLTA4 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for LTA4 is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of LTA4 bound in the initial step. The color development is stopped and the intensity of the color is measured.

Detection Method: Colorimetric

Conjugate: N/A

Sample Type: Cell culture supernatants#Serum#Plasma#Other biological fluids

Assay Type: Multiple steps standard sandwich ELISA assay with a working time of 3-5 hours. It depends on the experience of the operation person.

Usage Note: • 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.

Storage Instruction: The unopened kit should be stored at 2 - 8°C. After opening, please store refer to protocols.

Shipping: Gel pack with blue ice.

Background: Leukotriene A4 is a leukotriene.Leukotriene A4 hydrolase converts it to Leukotriene B4. (2s- (2 alpha, 3 beta (1e, 3e, 5z, 8z) ) ) -3- (1, 3, 5, 8-tetradecatetraenyl) oxiranebutanoic acid. An unstable allylic epoxide, formed from the immediate precursor 5-hpete via the stereospecific removal of a proton at c-10 and dehydration.  Leukotriene A4  (LTA4) is synthesized in mast cells, eosinophils, and neutrophils from arachidonic acid by 5-lipoxygenase (5-LO), which exhibits both lipoxygenase and LTA4 synthase activities.1, 2 LTA4 is rapidly metabolized by LTA4hydrolase or LTC4 synthase to LTB4 or LTC4, respectively.2 LTA4, from leukocytes, is known to undergo transcellular metabolism in platelets, erythrocytes, and endothelial cells.3 Further metabolism of LTA4 by 15-LO leads to lipoxin biosynthesis.2 LTA4 as a free acid is highly unstable. The methyl ester is stable and can be readily hydrolyzed to the free acid as needed.
