Pre-submission QC checklist for DNA and RNA samples sent for sequencing v1

Samples sent to a sequencing provider often fail the provider's incoming QC for avoidable reasons: too little material, a concentration measured only by NanoDrop, leftover salts or phenol, degraded RNA, or the wrong buffer. This checklist walks a first-time user through five quick checks before shipping. Always follow your provider's own sample requirements for your method and kit; they take priority.
