WebThe probes are specifically designed for the gene of interest, so that they will hybridize with RNA sequences on the blot corresponding to the sequence of interest. The blot membrane is washed to remove unwanted … WebPrepare 100 ml of 0.5X TBE electrophoresis buffer for wetting the papers. Wet two of the filter papers and place them on the cathode plate of the electroblotter. Use a glass pipet to roll out any air bubbles that may inhibit transfer. After gel electrophoresis, separate the glass plates and immobilize the gel onto a piece of filter paper.
WebSouthern and Northern blotting protocols involve the following major steps: Purification of DNA/RNA: Extract and purify the DNA/RNA from either cells or tissue sources. Digestion of DNA: Digest the DNA into fragments with restriction enzymes. This step is not required for RNA. Gel electrophoresis: Separate the DNA fragments on agarose gel.
