Enhanced K-Blue® Substrate (TMB)高敏性呈色劑
Enhanced K-Blue® Substrate (TMB),
Enhanced K-Blue® is a one bottle stabilized chromogenic substrate for use with horseradish peroxidase immunoassays. It contains both 3,3’,5,5’ tetramethylbenzidine (TMB) and hydrogen peroxide (H2O2) in a one bottle format with long term stability and high sensitivity. Enhanced K-Blue develops a deep blue color in the presence of peroxidase labeled conjugate, and is not applicable for use with assays requiring a precipitating substrate. This formulation does not contain DMF or DMSO.
Enhanced K-Blue is a highly sensitive substrate with kinetic reactions equivalent to Neogen’s original K-Blue substrate formulation. This formulation offers the advantage of containing no DMF or DMSO and has very low background.
Enhanced K-Blue is stable for a minimum of 48 months when stored at 4°C.
目前Neogen 已有的TMB 產品,活性與時間比較僅略輸給K-blue advance但其高敏性已足以進行各項實驗,因此配方相當穩定所以為長效期TMB
