The invention relates to enzyme detection assay compositions and methods which have chromogenic and nonchromogenic, hypochromogenic, bathochromogenic or hypsochromogenic substrates. By using both chromogenic and nonchromogenic, hypochromogenic, bathochromogenic or hypsochromogenic substrates assay sensitivity can be controlled and the need for sample predilution eliminated. In one embodiment of the invention an assay for the estimation of serum cholinesterase activity is provided.
本发明涉及酶检测化验组合物和方法,这些组合物和方法具有致色性和非致色性、低致色性、浴致色性或低次致色性底物。通过同时使用发色性和非发色性、低发色性、浴变色性或低变色性底物,可以控制检测灵敏度,并消除对样品预稀释的需要。在本发明的一个实施方案中,提供了一种用于估算血清胆碱酯酶活性的检测方法。
