PCR arrays are dedicated to gene expression analysis by quantitative PCR. They are sets of primers, on the same support (384-well microplate), selected according to a theme or a given biological process. PCR arrays can also be used for the validation of results obtained after transcriptomic analysis.
How does a PCR array work?
The PCR array system, with high-quality input RNA, yields single bands of the predicted size without primer-dimers or other secondary products, therefore providing the highly accurate real-time PCR results (see figure ” A single gene-specific product in every reaction”).
What are the 3 main components of the cytoskeleton and what are their main roles?
Three major types of filaments make up the cytoskeleton: actin filaments, microtubules, and intermediate filaments. Actin filaments occur in a cell in the form of meshworks or bundles of parallel fibres; they help determine the shape of the cell and also help it adhere to the substrate.
What are the three types of cytoskeleton?
In eukaryotes, there are three types of protein fibers in the cytoskeleton: microfilaments, intermediate filaments, and microtubules.
What is PCR microarray?
Microarray technology is ideal to screen a lot of genes in one step (>10,000 gene transcripts) and kinetic RT-PCR is very sensitive, highly quantitative and requires up to 1000-fold less RNA. Both allow a relative and accurate quantification of mRNA molecules with a sufficiently high repeatability and low variability.
What are the 3 protein structures that make up the cytoskeleton?
The cytoskeleton of a cell is made up of microtubules, actin filaments, and intermediate filaments. These structures give the cell its shape and help organize the cell’s parts. In addition, they provide a basis for movement and cell division.
Is cytoskeleton prokaryotic or eukaryotic?
Initially, it was thought that the cytoskeleton was exclusive to eukaryotes but in 1992 it was discovered to be present in prokaryotes as well. This discovery came after the realization that bacteria possess proteins that are homologous to tubulin and actin; the main components of the eukaryotic cytoskeleton.
What is the difference between microtubule and microfilament?
Microtubules and microfilaments are two components of the cytoskeleton of a cell. The main difference between microtubules and microfilaments is that microtubules are long, hollow cylinders, made up of tubulin protein units whereas microfilaments are double-stranded helical polymers, made up of actin proteins.
