probe

A small utility program that is used to investigate, or test, the status of a system, network or Web site. Probes are mostly used for lawful purposes to determine if a device is functional. They can also be used by crackers to locate weaknesses in the system. A Web probe analyzes a Web site and reports data such as response time, security protocols supported and type of Web server. See ping.

1. something that searches into, examines, or tests; e.g. an instrument or tube used for exploring a cavity or sampling a fluid, or an electric conductor introduced into an electric circuit or a cavity resonator to provide electric coupling to an external circuit.
2. (in biochemistry) a chemical species, or a chemical group attached to a carrier molecule, used to investigate the chemical nature of some other particular chemical species or the physical nature of a particular environment, especially within an intact cell; a reporter group. Typically some measurable physical property of the probe (e.g. fluorescence, electron spin resonance) alters in a way that can be correlated with changes in the environment or in the macromolecule. Examples are a group having paramagnetic properties, for detection using electron spin resonance (see, e.g., TEMPO), and a fluorescent lipid molecule used to report membrane fluidity (see, e.g., parinaric acid).
3. (in molecular biology) or gene probe or hybridization probe an oligo- or polynucleotide that is complementary to an oligonucleotide or nucleic-acid sequence under investigation. The probe is normally labelled in a way that permits its ready detection, e.g. with a radioactive isotope or a fluorescent constituent. Hybridization of the probe to the oligonucleotide sequence under investigation allows that sequence to be detected. The technique finds much use in screening gene libraries, detecting oligonucleotides on blots of electrophoresis gels, and in other associated technologies.
4. to examine with or as with a probe.
