一般描述
）中的铜（II）进行预处理。酚试剂的加入可产生在550-750 nm间提高吸光值的色原。通常，在尖峰（750 nm）或肩峰（660 nm）处的吸光度用于定量1-100 mg/ml之间的蛋白浓度，而550nm处的吸光度用于定量更高的蛋白浓度。
在没有铜的情况下，颜色强度主要由蛋白中的酪氨酸和色氨酸含量决定，并在较小程度上由半胱氨酸和组氨酸决定。铜(II)对由酪氨酸、色氨酸或组氨酸而形成的颜色没有影响，但会由于半胱氨酸而减少颜色形成。
许多对原始检测流程的修改已得到发表，包括用于增强显色、测定不溶性蛋白含量以及过程的自动化。多种物质包括许多缓冲剂、螯合剂、去污剂和环状有机化合物都可对Lowry蛋白检测产生干扰。
Folin & Ciocalteu酚试剂可在色谱过程中用作喷雾剂。
