Figure 1. Functional stability of HRP encapsulated in agarose gels.

Percent activity retained for solution phase HRP (white bars) and HRP encapsulated in 0.5% agarose (gray bars) and 2% agarose (black bars) in the presence of 35% ethanol and isopropanol. The relative activities were calculated by normalizing the activity in the presence of denaturants to the activity in buffer. Error bars indicate the standard deviation of triplicate measurements.
