Detection Method:Sandwich
Test principle:This assay employs a two-site sandwich ELISA to quantitate VCP in samples. An antibody specific for VCP has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyVCP present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for VCP 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 VCP bound in the initial step. The color development is stopped and the intensity of the color is measured.
Product Overview:VCP is a member of a family that includes putative ATP-binding proteins involved in vesicle transport and fusion, 26S proteasome function, and assembly of peroxisomes. VCP, as a structural protein, is associated with clathrin, and heat-shock protein Hsc70, to form a complex. VCP has been implicated in a number of cellular events that are regulated during mitosis, including homotypic membrane fusion, spindle pole body function, and ubiquitin-dependent protein degradation.
Clathrin is a structural protein found in coated pits and vesicles, organelles which are important in membrane trafficking functions such as endocytosis and Golgi sorting. A 100-kD protein, designated valosin-containing protein or VCP by early investigators, is a structural protein complexed with clathrin.
