What is the voltage probe?

The Voltage Probe is a bipolar sensor. The black lead is grounded along with the interface, and the sensor reports the potential difference between the red lead and ground. It can be used to measure the potential in DC or AC circuits. You might also consider the Differential Voltage Probe.

Then, what is a test probe?

A test probe is a physical device used to connect electronic test equipment to a device under test (DUT). Test probes range from very simple, robust devices to complex probes that are sophisticated, expensive, and fragile.

What is the differential probe?

Oscilloscope High Voltage Differential Active Probes. A “differential” probe is an active probe which has two inputs, one positive and one negative as well as a separate ground lead and it drives a single terminated 50Ω cable to transmit its output to one oscilloscope channel.

What is a current probe?

In electrical and electronic engineering, a current clamp or current probe is an electrical device with jaws which open to allow clamping around an electrical conductor.

What is high voltage probe?

The 80K-40 is a high voltage probe designed to extend the voltage measuring capability of an AC/DC voltmeter to 40,000 volts peak AC or DC Overvoltage Category I. This means the probe can only be used to make measurements on energy limited circuits within equipment.

What is a 10x oscilloscope probe?

The 1X probes are suitable for many low frequency applications. They typically offer the same input impedance of the oscilloscope which is normally 1 M Ohm. The most common type of probe with a built in attenuator gives an attenuation of ten, and it is known as a 10X oscilloscope probe.

What is the use of trigger in oscilloscope?

An oscilloscope’s trigger function is important to achieve clear signal characterization, as it synchronizes the horizontal sweep of the oscilloscope to the proper point of the signal. The trigger control enables users to stabilize repetitive waveforms as well as capture single-shot waveforms.

What is a probe used for in biology?

In molecular biology, a hybridization probe is a fragment of DNA or RNA of variable length (usually 100–1000 bases long) which can be radioactively labeled. It can then be used in DNA or RNA samples to detect the presence of nucleotide sequences (the DNA target) that are complementary to the sequence in the probe.

What is meant by DNA probe?

DNA probes are stretches of single-stranded DNA used to detect the presence of complementary nucleic acid sequences (target sequences) by hybridization. DNA probes are usually labelled, for example with radioisotopes, epitopes, biotin or fluorophores to enable their detection.

What does a microarray measure?

A DNA microarray (also commonly known as DNA chip or biochip) is a collection of microscopic DNA spots attached to a solid surface. Scientists use DNA microarrays to measure the expression levels of large numbers of genes simultaneously or to genotype multiple regions of a genome.

How do you know if a gene is turned on or off?

Each cell expresses, or turns on, only a fraction of its genes. The rest of the genes are repressed, or turned off. The process of turning genes on and off is known as gene regulation. Signals from the environment or from other cells activate proteins called transcription factors.

What does the microarray test for?

Chromosomal microarray (CMA) is increasingly utilized for genetic testing of individuals with unexplained developmental delay/intellectual disability (DD/ID), autism spectrum disorders (ASD), or multiple congenital anomalies (MCA).

How long does it take to get results from a microarray test?

Prenatal microarray results generally take 5-7 days to complete. However, it is common for this test to be performed after the completion of the baby’s karyotype test. A karyotype test requires cells grown from an amniocentesis or CVS sample, which typically takes 10-12 days.

How does a microarray work?

By identifying which genes in the cancer cells are working abnormally, doctors can better diagnose and treat cancer. One way they do this is to use a DNA microarray to determine the expression levels of genes. When a gene is expressed in a cell, it generates messenger RNA (mRNA).

What does each spot on a microarray represent?

RNA is extracted from the two cells, and is labelled with different dyes (red and green) during the synthesis of cDNA by reverse transcriptase. Following this step, cDNA is hybridized onto the microarray slide, where each cDNA molecule representing a gene will bind to the spot containing its complementary DNA sequence.

What does the DNA chip do vape?

The DNA 200 is a vaping chip-set made by Evolv. Evolv are a US based manufacturer famous for their temperature control chips that are used in vaping devices (mostly box mods). The USB port and Evolv’s Escribe software can be used to tailor or monitor the user experience.

What is a DNA 200 Mod?

The DNA 200 is a power regulated digital switch-mode DC-DC converter for personal vaporizers. It features Evolv’s patented Wattage Control, Temperature Protection, Preheat, Digital User Controls, OLED Screen, Onboard Buttons and Synchronous Rectification for maximum battery life and minimal heat generation.

What is a microarray data?

A microarray database is a repository containing microarray gene expression data. The key uses of a microarray database are to store the measurement data, manage a searchable index, and make the data available to other applications for analysis and interpretation (either directly, or via user downloads).

What does RNA sequencing tell you?

RNA sequencing (Wang 2009) is rapidly replacing gene expression microarrays in many labs. RNA-seq lets you quantify, discover and profile RNAs. For this technique, mRNA (and other RNAs) are first converted to cDNA. The cDNA is then used as the input for a next-generation sequencing library preparation.

What is read in sequencing?

A read refers to the sequence of a cluster that is obtained after the end of the sequencing process which is ultimately the sequence of a section of a unique fragment. If an RNA is expressed in high copies then there will be more reads coming from it; reads can be redundant as well.

What is deep sequence?

If deep sequencing means the depth of coverage–the number of times, on average, a nucleotide is sequenced–depending on the project’s goals, the size of the genome, and so on, sometimes we sequence deeply, sometimes we don’t.

What does sequence coverage mean?

Coverage (or depth) in DNA sequencing is the number of unique reads that include a given nucleotide in the reconstructed sequence. Deep sequencing refers to the general concept of aiming for high number of unique reads of each region of a sequence.

What is a shotgun sequence?

In genetics, shotgun sequencing is a method used for sequencing long DNA strands. It is named by analogy with the rapidly expanding, quasi-random firing pattern of a shotgun.

What is metagenomic shotgun sequencing?

Shotgun metagenomics also provides a means to study unculturable microorganisms that are otherwise difficult or impossible to analyze. Unlike capillary sequencing or PCR-based approaches, next-generation sequencing (NGS) allows researchers to sequence thousands of organisms in parallel.
