Isolating intact total RNA from tissue samples varies in difficulty with the physical and biochemical nature of that tissue. While many methods will work equally well for tissues such as liver, fibrous tissues (e.g. heart), fatty tissues (e.tg. brain), and nuclease-rich tissues (e.g. spleen) are more challenging.

A range of products developed by our RNA experts will help you isolate high yields of pure, intact RNA from almost any type of tissue.

RNA Yields From Animal Tissues

RNA content can vary widely between tissues, cell types, physiological states, etc. This chart provides general guidelines for estimating RNA yields from a variety of cells and tissues.

Preserve and Stabilize Your RNA

RNAlater® Solution is widely used for the preservation of RNA in intact animal tissues, organs, and cells, and bacteria. It eliminates the need to immediately process samples for RNA isolation or to freeze them in liquid nitrogen for later processing.
