what is the difference between direct probe and amplified probe?

Nucleic acid probes can identify microorganisms more rapidly than traditional culture. Direct probes identify organisms that are present using immunoassays or fluorescence in situ hybridization (FISH). Polymerase chain reaction (PCR) can be used to amplify probe signals to increase the sensitivity of detection.

Multimeters are tools used to measure current, voltage and resistance. The primary difference between the two is the display, an analog multimeter uses a needle to show the value, while a digital multimeter will show the results as numbers on a screen. ...

The Power Probe 3 is our most popular Circuit Tester. ... The Power Probe 4 adds more multi-meter functions like Resistance testing, Frequency, AC Voltage, and special test modes like Injector Testing and a Driver Circuit Tester, dramatically increasing the testing capabilities.

What is the difference between direct detection and indirect detection of extra-solar planets? Direct Detection is when the exoplanet is visible through a telescope, while indirect detection refers to the situation where an exoplanet cannot be seen, but its existence is inferred from the behavior of its host star.

For example, a 26 gauge needle has an O.D. (outer diameter) of 0.46 mm and an I.D. of 0.26 mm while the 26s gauge needle has an O.D. of 0.47 mm and an I.D. of 0.13 mm. ... Also, the difference in the wall thickness nearly doubles with 26s gauge having a thickness of 0.18 mm while the 26 gauge is only 0.10 mm.

Active sensors have its own source of light or illumination. In particular, it actively sends a pulse and measures the backscatter reflected back to the sensor. But passive sensors measure reflected sunlight emitted from the sun. When the sun shines, passive sensors measure this energy.

The main difference between acid base indicator and universal indicator is that acid base indicators show color changes at a certain pH range whereas universal indicators show color changes at a wide variety of pH values ranging from 0 to 14.

Pulse start and probe start lamps use different ballast systems. Traditional probe start metal halide lamps do not use igniters and require three electrical contacts to ignite the gas and remain lit. Newer pulse start metal halide lamps use only two contacts and use an igniter located inside the ballast pod.

Standard has the analog meter but there is no difference in matter of power. The only difference between them is it's colors and speedometer display. Std has manual display while dlx has digital one.

Analog signals use a continuous variety of amplitude values whereas digital signal takes a limited set of distinct values at consistently spaced spots in the time. Analog signals are continuous in nature, whereas digital signals are discrete.

Antenna gain: is the relative measurement of an antenna's ability to direct or concentrate the radiated signal emitting from it. Gain is measured in Dbi (decibels relative to an isotropic radiator) or Dbd (decibels relative to a dipole radiator). ... A change in power by a factor of 10 is a 10 dB change in level.

The main difference that you need to know is that a direct lit fixture is illuminated by a light source that is at the back of the panel. ... Edge lit panels, on the other hand, produce the light from the sides of the panel. This allows them to be much thinner, around a half inch thick.

What is the difference between direct and indirect staining? Direct staining is done with basic dye while indirect staining is done with acidic dye. Using an indirect stain allows you to see the bacterial cells much more accurately, as well as a clearer shape and size.

RFLP analysis is often used for DNA profiling. Real-time PCR on the other hand, utilizes heat-stable DNA polymerases to amplify minute quantities of DNA especially when more DNA template is required for further reactions/analysis.

Microcurrent is an alternating current. ... Unlike Galvanic, both probes in True Microcurrent are on the face simultaneously and each probe provides both the negative and positive charge. Microcurrent is different from Galvanic because Galvanic works with the chemical reaction of the solution and the current.

Today, we'll answer what the difference is, technically, between direct fired and indirect fired? “Direct Fired” means just that; the burner is fired directly into the process air stream to heat it. ... “Indirect Fired” means that the air is heated “indirectly”; the burner is fired into a heat exchanger.

The key difference is, that an OTA has three inputs while your OpAmp has only two. Besides the two differential input terminals that an OTA and an OpAmp share, the OTA has a third input that lets you set the gain of the amplifier by applying a current.
