a new and promising tool that allows the detection of several hundred or even thousands DNA sequences simultaneously
an example of the enormous efforts undertaken in the genomic field in the last few years Many applications and technologies adapted to these applications use biochips
a powerful method for exploring biological processes on a genomic scale
a powerful method for monitoring the expression level of thousands of genes, or even whole genomes, in a single experiment
a powerful technique in screening and locking differentially expressed genes in gliomas, LNX was closely related to human gliomas and suggested playing an important role in gliomas by notch signal approach
a powerful technique that was recently developed in order to analyze thousands of genes in a short time
a very sensitive method that allows one to analyze thousands of genes simultaneously
The study of large numbers of genes very quickly by using advanced computers and software programs connected to a scanning microscope. Traditional slides and labels are used to prepare the DNA for scanning; advanced technology has accelerated the process.
An automated, high-throughput technique for simultaneously analyzing thousands of different DNA sequences or proteins affixed to a thumbnail-sized "chip" of glass or silicon. DNA microarrays can be used to monitor changes in the expression levels of genes in response to changes in environmental conditions or in healthy versus diseased cells. Protein arrays can be used to study protein expression, protein–protein interactions, and interactions between proteins and other molecules.
A new way of studying how large numbers of genes interact with each other and how a cell's regulatory networks control vast batteries of genes simultaneously. The method uses a robot to precisely apply tiny droplets containing functional DNA to glass slides. Researchers then attach fluorescent labels to DNA from the cell they are studying. The labelled probes are allowed to bind to complementary DNA strands on the slides. The slides are put into a scanning microscope that can measure the brightness of each fluorescent dot; brightness reveals how much of a specific DNA fragment is present, an indicator of how active it is.
