Detection is performed by aminoacylation of tRNA with H3-lableled lysine using aminoacyl tRNA synthetase from bovine liver. For long-term storage (years), it is recommended that this product be stored at -80 degrees at a concentration of no less than 0.5mg/ml. For short-term storage, this product is stable at -20 degrees for a minimum of one year. Please contact us for more details!
