Fig. 5From: Methods of high integrity RNA extraction from cell/agarose constructConcentration (ng/µl), ratio of OD 260/280 nm and OD 260/230 nm by spectrophotometry. In the cell-only control, concentration, OD 260/280 nm and OD 260/230 nm were 263.47 ± 49.2 (ng/µl), 1.93 ± 0.06 and 0.56 ± 0.12, respectively. The bars stand for the standard deviations (n = 3)Back to article page
