Abstract
These samples are part of the JAX-Sen project in the SenNet Consortium. Here we provide details on specimen collection and shipment to the Robson laboratory at The Jackson Laboratory for Genomic Medicine (JAX-GM) in Farmington, CT for its processing for Bulk RNA-sequencing (Bulk RNA-seq).
Reagents and Materials:
Reagents and Materials:
2mL Eppendorf tubes or 5 ml Eppendorf tubes
RNA Later solution
Wet Ice
Tweezers (clean, sterile)
Quality Key Points:
Quality Key Points:
The tissue specimen should be always kept at 4 degrees Celsius and RNase-free.
It is crucial to not store the tissue specimen at RT to avoid any cell death, and tissue and/or RNA degradation.
Procedure:
Procedure:
Timeline: The daily shipping deadline at Jax BH is 12:00 noon. So, harvest the tissues before and closer to noon.
Collection/Harvest:
Animal was euthanized via cervical dislocation.
Animal was pinned to a necropsy tray which remained on wet ice throughout the harvest.
Animal was perfused with 20ml cold PBS.
Heart, pancreas, and kidney was collected and the specimen was transferred into tubes containing ice-cold RNA later (the volume will depend on the size of the specimen, but should cover abundantly the tissue and fill up the tube)
Individually parafilm the Eppendorf tube lids to their tubes before shipping.
Keep at 4 degrees Celsius thereafter, until shipping.
Shipping:
Place sample tubes in a plastic box (cardboard boxes insulate the samples from the cold ice) or in double Ziplock bags after checking that they are completely sealed.
