Detection Method:Sandwich
Test principle:This assay employs a two-site sandwich ELISA to quantitate TOMM22 in samples. An antibody specific for TOMM22 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyTOMM22 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for TOMM22 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 TOMM22 bound in the initial step. The color development is stopped and the intensity of the color is measured.
Product Overview:The translocase of outer mitochondrial membrane (TOM) complex is a multisubunit complex involved in the recognition, unfolding, and translocation of preproteins from the cytosol into the mitochondria. The deduced 142-amino acid human protein, which is approximately 33% similar to the yeast proteins, contains an N-terminal negatively charged region, an internal hydrophobic transmembrane region, and a C-terminal region with a glutamine-rich segment. Immunoblot analysis and fluorescence microscopy showed expression of a 21-kD mitochondrial membrane protein with its N and C termini exposed to the cytosol and intermembrane space of the mitochondrial outer membrane, respectively.An association between the rat Tomm22 protein, which is 94% identical to the human protein, and Tomm40 was observed.
