Application

Suitable for use as a carrier in nucleic acid purification and precipitation.

Crude transfer RNA (tRNA), purified from wheat germ, contains many specific tRNA molecules that can be separated by different processes. Experiments for detailed investigation of structure and function using in vitro translation systems often require highly purified tRNA, which can be achieved by combinations of chromatographic separations and reversible biochemical modification of the tRNA. Wheat germ tRNA has been used for the purification of RNAse Z (tRNA 3′- processing endonucleases) from wheat germ. The purification included six steps with the most efficient one using an affinity column made of wheat germ tRNA, which the RNAse Z bound tightly.

Components

tRNA is provided as a lyophilized powder that is soluble in water at a concentration of 2 mg/ml.
