A large repertoire of immunological methods permits monitoring the interaction of antibodies with their specific antigen. However, recognition of a protein by a conformation-specific antibody represents a challenge because native conditions must be kept throughout the assay. Native immunoblotting of blue native gels conserves the native state by using Tween 20 instead of methanol for the obligatory destaining of the blot membrane. We validate the new technique with a set of monoclonal antibodies against respiratory NADH:ubiquinone oxidoreductase.

Western Blotting01:15

Western Blotting

Western blotting is an analytical technique for protein identification. It has various applications in immunology and medicine, including detecting diseases like bovine spongiform encephalopathy, mad cow disease, and human and feline immunodeficiency virus from biological samples.
The technique begins with separating proteins from the sample using sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE), followed by protein transfer, immunoblotting, and finally, protein detection.

Southern Blot

Agarose gel electrophoresis is very useful in separating DNA fragments by size. Running a DNA ladder containing fragments of the known length alongside the sample helps determine the approximate length of the sample DNA fragments. However, additional steps are needed to verify the sequence identity of the sample DNA fragments.
Denatured DNA fragments must be transferred onto a carrier membrane from the gel to make it accessible to a probe - a small ssDNA fragment complementary to the target DNA...
