It shows no cross-reaction with Topoisomerase II beta or I. Topo II Alpha plays important roles in synthesis and transcription of DNA as well as chromosomal segregation during mitosis. It is reported to be a sensitive and specific marker of late S-, G2- \u0026amp; M-phases in transformed and developmentally regulated normal cells. Topo II Alpha is also implicated in drug resistance of tumor cells and has been shown to be over-expressed in many human cancers. Decreased expression of Topo IIa is the predominant mechanism of resistance to several chemotherapeutic agents.\u003c\/p\u003e","brand":"NSJ Bioreagents","offers":[{"title":"100 ug \/ Mouse","offer_id":49474007925016,"sku":"V4483-100UG","price":539.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0590\/5652\/1400\/files\/get_image_c78041ad-2874-4bfc-9419-b8cfd9f8d5fa.jpg?v=1734422954","url":"https:\/\/danabiosci.com\/products\/v4483-100ug","provider":"Dana Bioscience","version":"1.0","type":"link"}
