Measuring the purity of mRNA can be done by measuring its absorbance at 260 nm. An absorbance of 1.0at 260 nm is equivalent is equivalent to 40 mg mRNA. An additional reading at 280 nm allows the A260:A280 ratio to be calculated. A ratio of 2.0 should be expected. The integrity of the mRNA can …

In order to linearize or denature RNA, it can be achieved by heating to 80-90o for 5 minutes, then cooling quickly on ice (taking care not to cause precipitation of the loading-buffer components) and immediately applying it. The step above can reduce the RNA …

RNA extraction from blood will be more successful if the nucleated white cells are first isolated from the red cells since the red cells are a rich source of ribonucleases that are able to degrade RNA. …
