WebThis antibody enables the quantification of cisplatin-induced adducts on DNA. It has also been recently used for isolation of DNA fragments carrying adducts to enhance the sensitivity of subsequent PCR-based analyses and is central to ongoing studies of variation in the nature of cisplatin adducts formed in different cell lines. WebCisplatin is among the most widely used broadly active cytotoxic anticancer drugs; however, its clinical efficacy is often limited by primary or the development of secondary resistance. Several mechanisms have been implicated in cisplatin resistance, including reduced drug uptake, increased cellular thiol/folate levels and increased DNA repair.
