The document describes miScript miRNA PCR Arrays, which enable comprehensive profiling of miRNAs for disease research and biomarker discovery. The arrays use a validated PCR technique to quantify miRNA expression levels from tissue samples. They are available in customizable panels focused on specific biological pathways, diseases, or the entire miRNome. The workflow involves isolating miRNA from samples, converting it to cDNA, and running real-time PCR on the array to obtain expression data for targeted miRNAs. The technique provides sensitive and reproducible miRNA profiling to explore their roles in biological contexts and diseases.
