Classification of experimental values into classes. Each experimental condition was classified into three or five classes depending on its value

Class	1	2	3	4	5
pH	0 to 7.0	7.0 to 8.0	8.0 to 14	–	–
Temp. (°C)	0 to 25	25 to 30	30 to 40	–	–
Ionic strength	0 to 0.032	0.032 to 0.066	0.066 to 0.14	0.14 to 0.17	0.17 to 0.40
Protein conc. (Log μM)	−1.64 to −0.49	−0.49 to −0.29	−0.29 to 0.84	0.84 to 1.5	1.5 to 2.7
RNA conc. (Log μM)	−4.7 to −3.7	−3.7 to −2.4	−2.4 to −1.0	−1.0 to −0.12	−0.12 to 2.3
