Description_x000D_ General description_x000D_ Wheat germ tRNA contains many different specific tRNA molecules._x000D_ Application_x000D_ 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._x000D_ Suitable for use as a carrier in nucleic acid purification and precipitation._x000D_ Packaging_x000D_ 2500, 10000 units in glass bottle_x000D_ 500 units in poly bottle_x000D_ Components_x000D_ tRNA is provided as a lyophilized powder that is soluble in water at a concentration of 2 mg/ml._x000D_ Unit Definition_x000D_ One unit will yield an absorbance of 1.0 at 260 nm in 1.0 mL of water (1 cm light path).
