Lysosomes are responsible for a number of cellular functions, including the degradation of various biological molecules. Soluble enzymes within the lysosomal lumen are required to perform this function. Lysosomal activity can be disrupted in a variety of diseases, and measuring the activity of specific enzymes can be performed. In this chapter, we detail how lysosomal enzyme activity can be measured either in cell lysates or intact cells. This can be used to study fundamental cell biology or the effect of therapeutics targeting lysosomal function.
