TABLE 1C.

RNA purity (A260/280; A260/230), standardized yields and RIN (RNA integrity number) for organic isolation-based groups after additional purification step.

	RNAzol only (n = 4)	Beads-beating (n = 4)	Lysozyme (n = 4)	Cell disruption (n = 4)	Lysozyme + beads (n = 4)
A260/280	1.91 ± 0.07	1.93 ± 0.06	1.83 ± 0.26	1.97 ± 0.09	1.95 ± 0.05
A260/230	1.38 + 0.41	1.50 ± 0.30	1.59 ± 0.27	1.61 ± 0.36	1.60 ± 0.31
Standardized RNA yields (pg/g dry sample)	180.75 ± 101.77	177.26 ± 88.80	233.97 ± 126.74	200.70 ± 147.26	233.13 ± 130.48
RNA integrity number	2.675	2.675	2.65	2.55	2.575

The variability reflects the standard deviation.
