Deoxyribonucleic acid probe

Nucleic acid (deoxyribonucleic acid (DNA) and ribonucleic acid (RNA)) probes utilize labeled, ie, radioactive, enzymatic, or fluorescent, fragments of DNA or RNA (the probe) to detect complimentary DNA or RNA sequences in a sample. Because the probe is tailored for one specific nucleic acid, these assays are highly specific and very sensitive (45).

Blot overlays include the probing of membrane with various molecules to detect the presence of specific binding domains, for example, with guanine triphosphate (25,26) or proteoglycans (27). In the Southern or North Western blotting, the membrane is probed with deoxyribonucleic acid or ribonucleic acid molecules to detect nucleic-acid binding proteins (28). 

There is an ongoing requirement in cell and molecular biology for the preparation of antibodies to use as probes for specific proteins. Two main strategies exist to raise appropriate antibodies. A complimentary deoxyribonucleic acid (cDNA), or gene sequence encoding the protein of interest can be expressed in a heterologous species,...
