Surface plasmon resonance imaging (SPRi) brings label-free detection of molecular interactions to microarray analysis. The arrayed molecules (probes) may be proteins, peptides, nucleic acids ...

Advances in material science combined with nanofabrication and computational design have led to the discovery of label-free protein microarray techniques. These techniques are of enormous benefit ...

A protein microarray consists of the immobilization of proteins in organized rows and columns upon a support structure. ... Overcoming challenges in both label-based and label free protein ...

In fact, microarray analysis enables researchers to look at expression patterns across all of the genes in an entire genome — and to do so in a single procedure.

Microarray analysis can be performed to assess differences in gene expression between two different samples. After isolating nucleic acids from the two samples, one sample is labeled with a dye ...

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).
