DNA topoisomerase 1 isa DNA topoisomerase, an enzyme that controls and alters the topologic states of DNA during transcription. This enzyme catalyzes the transient breaking and rejoining of a single strand of DNA which allows the strands to pass through one another, thus altering the topology of DNA. This gene is localized to chromosome 20 and has pseudogenes which reside on chromosomes 1 and 22.Type IA topoisomerases creates a single break in DNA, and passes a second strand or duplex through the break. This strand passage mechanism shares several features with type IIA topoisomerases. They both form a 5' phosphotyrosine intermediate, and require a divalent metal ion to perform its work. Unlike type II topoisomerases, type IA topoisomerases do not use energy to do its work
Mouse DNA topoisomerase 1 (TOP1) ELISA Kit employs a two-site sandwich ELISA to quantitate TOP1 in samples. An antibody specific for TOP1 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyTOP1 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for TOP1 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 TOP1 bound in the initial step. The color development is stopped and the intensity of the color is measured.
