Transfer RNA is isolated from brewer’s yeast. This transfer RNA is specific for transfer of the amino acid phenylalanine. This product is not suitable for use as carrier tRNA to aid in the ethanol precipitation of very small amounts of DNA. ||CAS No:|63231-63-0||Phenylalanine Acceptor Activity (100% pure tRNA):|1800 pmoles per A260 unit||Activity:|The assay for this product is based on a published method. The activity is measured using a crude preparation of phenylalanyl transfer ribonucleic acid synthetase. The phenylalanine specific tRNA is used as a substrate for the enzyme in the assay.||Applications:|Suitable for use:|• As a tRNA standard|• As a substrate in tRNA synthatase assays|• As a substrate in other reactions involving tRNAs||Solubility (water):|2mg/ml||Appearance:|Supplied as a white to tan powder.||Storage and Stability:|Stable for 6 months after receipt at 4°C. Avoid contamination with RNase from bacteria or human skin.
