The qPCR Arrays are designed for profiling the expressions of pre-made or customized sets of coding-genes in various tissues or cells. The resulting differential expressions of profiled genes help researchers to identify those that are biologically significant and relevant to their research. An array can contain hundreds of primers for human genes or miRNA carefully chosen based on a thorough literature search of peer-reviewed publications.
In a typical 96-well plate there are up to 84 pairs of qPCR primers and 12 wells of controls which are used to monitor the efficiency of the entire experimental process- from reverse transcription to qPCR reaction. Each pair of primers used in the qPCR arrays has been experimentally validated to yield a single dissociation curve peak and to generate a single amplification of the correct size for the targeted mRNA.
From the RNA/miRNA provided, first-strand cDNA is synthesized through reverse transcription which is later mixed with the qPCR reaction mix and distributed into the wells of the array and followed by the qPCR cycling. The qPCR result is analyzed with a Data Analysis System using the ΔΔCT method to perform fold-change analysis or simple statistical analysis of the expression level (CT or CP values) for each gene.
