The effects of 1 percent (wv-1) disaccharides and PEG-6000 on the activity (initial rates) of α-chymotrypsin precipitated by n-propanol.

Disaccharide
Initial rate (nmoles mg-1min-1.)

None
16.6
Trehalose
33.5
Trehalose + PEG-6000(1 percent wv-1)
38.1
Sucrose
26.0
Lactose
33.7
PEG-6000 (1 percent wv-1)
19.6

Initial rates were calculated from aliquots taken over 10 to 60 min. The percentage conversions during these time periods were 1–30 percent and in a linear range.
