How do you analyze a microarray?
There are three main elements to consider when designing a microarray experiment.
First, replication of the biological samples is essential for drawing conclusions from the experiment.
Second, technical replicates (e.g. two RNA samples obtained from each experimental unit) may help to quantitate precision..
How do you perform a microarray analysis?
To perform a microarray analysis, mRNA molecules are typically collected from both an experimental sample and a reference sample.
For example, the reference sample could be collected from a healthy individual, and the experimental sample could be collected from an individual with a disease like cancer..
What are the major steps in preparing a microarray experiment?
There are four main steps to a DNA microarray analysis: Sample isolation/preparation, hybridization, washing, and image analysis.
Hybridization occurs when the samples (target and control) bond to probes with a complementary sequence..
What are the steps of preparing microarray experiment?
The microarray experiment is a multi-stage process in which the accuracy of each individual step may influence the gene expression estimates.
Precise understanding of each step is very important not only for the experimenter but also for the person performing data pre-processing..
What is analysis in a microarray analysis?
Microarray analysis techniques are used in interpreting the data generated from experiments on DNA (Gene chip analysis), RNA, and protein microarrays, which allow researchers to investigate the expression state of a large number of genes - in many cases, an organism's entire genome - in a single experiment..

What is the principle of microarray analysis?
The principle behind microarrays is that complementary sequences will bind to each other.
The unknown DNA molecules are cut into fragments by restriction endonucleases; fluorescent markers are attached to these DNA fragments.
These are then allowed to react with probes of the DNA chip..
- The DNA microarray is based on using an image analysis to detect hybridization of a target molecule to a specific probe immobilized on a solid base (March-Rossell\xf3, 2017).
Initially, specific probes of each gene are deposited onto a solid substrate (generally glass) in a lattice pattern. - There are four main steps to a DNA microarray analysis: Sample isolation/preparation, hybridization, washing, and image analysis.
Hybridization occurs when the samples (target and control) bond to probes with a complementary sequence.
The target sample refers to the treatment.
