Detection Method:Sandwich
Test principle:This assay employs a two-site sandwich ELISA to quantitate LRRK2 in samples. An antibody specific for LRRK2 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyLRRK2 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for LRRK2 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 LRRK2 bound in the initial step. The color development is stopped and the intensity of the color is measured.
Product Overview:LRRK2 encodes a protein with an ankyrin repeat region, a leucine-rich repeat (LRR) domain, a kinase domain, a DFG-like motif, a RAS domain, a GTPase domain, an MLK-like domain, and a WD40 domain. The protein is present largely in the cytoplasm but also associates with the mitochondrial outer membrane.LRRK2 interacts with the C-terminal R2 RING finger domain of parkin, and parkin interacted with the COR domain of LRRK2. Expression of mutant LRRK2 induced apoptotic cell death in neuroblastoma cells and in mouse cortical neurons. Mutations in this gene have been associated with Parkinson's disease type 8.Four LRRK2 gene variants found are found in a third of Parkinsons cases, but infrequent in the general population.
