Unit Definition: Shipping & Storage: One unit increases the absorbance of a high molecular weight DNA solution at a rate of 0.001 A260 units/min/ml of reaction mixture at 25°C. Store at room temperature (20-30°C). After reconstitution, place on ice until ready to use or store frozen aliquots (-20°C). Avoid repeated freeze/thawing. Add 275 |jl DNase/RNase-Free Water to reconstitute the lyophilized DNase I at 1 U/pl. Mix by gentle inversion. Reaction setup for DNA-free RNA: Mix by gentle inversion and incubate at room temperature for 15 minutes. Proceed with the RNA clean-up (e.g., RNA Clean &...
