We recommend immediate use of Dynabeads magnetic beads-mRNA complex or eluted mRNA for cDNA synthesis, in RT-PCR, or for other downstream applications. If storage is needed, we recommend you elute the mRNA from the beads using 10 mM Tris-HCl buffer (pH 7.5) and freeze it(-80°C). It is very important that all equipment and samples are RNase free.
