Block-dsrna 4x ivt reaction buffer
WebDilute the dsRNAs (from Step 27) and ssRNAs (sense and antisense strands from Step 23 serve as control) to a concentration of 0.1 µg/μL in 1× native gel-loading buffer. 30. Load … WebProduce the above master mix for each 96 well plate you wish to do an IVT reaction on. (We use the Ambion 5X T7 MEGASCRIPT Kit). IVT reaction buffer is extremely high in salt, so make sure the salt is fully dissolved before using the buffer. ½ IVT reactions produce around 30-60µg of dsRNA, enough to produce about 60 384-well assay plates.
