KPL TMB BlueSTOP Solution is formulated to stop color development in microwell assays and maintain the blue color of TMB. Unlike traditional acid-based TMB stopping solutions, the OD value of TMB does not change upon addition of KPL TMB BlueSTOP. The stopped substrate is stable for an extended period and can be read at 650 nm.
KPL TMB BlueSTOP is ideal for use with KPL SureBlue™ and KPL SureBlue Reserve™ 1-Component TMB, and KPL TMB 2-Component Microwell Peroxidase Substrate. The reagent is supplied as a convenient, ready-to-use solution that is stable for a minimum of one year.
