Macromolecule blotting and probing
A smear is a method for more constantly shifting proteins, nucleic acids, and ribonucleic acids onto such a carrier than gel electrophoresis. Nucleic (Southern blotch) and ribonucleic (Northern smudge) acids can be evaluated for precise groupings via complementary strands, while protein blends (Western and Eastern smears) can be tested for precise proteins. Microarrays, which are plates with an infinitesimal pocket of correlating DNA, can also be used to examine DNA.
