The reaction product of the ABTS Substrate Kit (SK-4500) is soluble in aqueous solutions. Because of its reproducibility and high extinction coefficient, this substrate is recommended for microtiter plate enzyme immunoassays. The green color produced in assays can be seen by eye or measured at 405 nm with conventional plate readers. This kit provides all of the necessary reagents to prepare about 300 ml of working solution. When stored at 4 ºC, this kit is stable for one year. |
