What is the probe for?

Probe is the contact medium of electrical test and the high-end precision electronic hardware component. It is a short single-stranded DNA or RNA fragment (about 20 to 500bp) used to detect its complementary nucleic acid sequence. Double-stranded DNA is denatured into single strand by heating, and then labeled with radioactive isotope (usually phosphorus -32), fluorescent dye or enzyme (such as horseradish peroxidase) to become probe.

Double-stranded DNA is denatured into single strand by heating, and then labeled with radioactive isotope (usually phosphorus -32), fluorescent dye or enzyme (such as horseradish peroxidase) to become probe. Phosphorus -32 is usually bound to the phosphate group of one of the four nucleotides that make up DNA, while fluorescent dyes and enzymes are covalently linked to nucleic acid sequences.
