A labeled probe is a piece of DNA or RNA that is used to detect the presence of a specific DNA or RNA sequence in a sample. Labeled probes can be used to screen a DNA library, which is a collection of cloned DNA fragments. The probe will bind to any DNA fragments in the library that contain the complementary sequence. Cloned cDNA, mRNA, and antibodies can all be used as labeled probes.
