We recommend storing DNAzol Reagent at room temperature. The DNAzol lysate (homogenate) can be stored 1 month at 15-30 degrees C; after 10 months at 4 degrees C or -20 degrees C, the DNAzol lysate (homogenate) has yielded high molecular weight genomic DNA, which can be completely digested with restriction enzymes and works well in PCR. During washes, DNA can be stored in 95% EtOH for at least one week at 15 degrees C to 30 degrees C or for three months at approximately 4 degrees C. DNA can be stored in DNAzol Reagent for one month at room temperature or 10 months at 4 degrees C.
