Sending in snap/fresh-frozen
Quickly cut tissues into smaller pieces (50~100 mg) on ice and freeze using liquid nitrogen. Store sample in pre-chilled RNase-free 1.5 mL/2.0 mL EP tubes or freezing tubes with a screw cap. Seal tubes with sealing film and stored at-80°C immediately. To ensure RNA preservation, it is recommended to complete this step within 3 minutes upon tissue removal from living body. Aliquot and store sample into several tubes to avoid degradation due to repeated freezing and thawing.
Sending in fresh(recommended)
If sending fresh organ or tissue samples without being snap-frozen, please use commercial RNA protection reagent (recommend MACS® Tissue Storage Solution) and follow manufacturer recommendation. (Shipping with ice packs for fresh tissues)
