BioChain’s Universal RNAs have been specifically designed for use as reference RNAs for microarray gene-profiling studies and other functional analyses. Our Universal RNAs are Total RNA controls derived from whole tissues sources. At BioChain, we pool extracted Total RNA from a collection of high-quality regional tissue sources in order to provide the broadest coverage of genes. Our Universal RNA is also systematically prepared on an industrial scale to minimize lot-to-lot variation and insure the highest quality RNA. By using pooled Universal Reference RNA from whole tissues you can get better gene representation, homogenous signal intensities across all genes, stable expression profiles, and high reproducibility between different lots.
