MicroRNAs (miRNAs) and small interfering RNAs (siRNAs) modulate gene expression. Along with several other classes of small noncoding RNAs (e.g. snRNA, snoRNA and piRNA), they have tremendous impact on a variety of biological processes.

While most traditional RNA isolation methods are not very efficient at recovering these smaller RNAs, several kits developed by our RNA experts offer quantitative recovery of small RNAs from a variety of sample types.
