Abstract

A system for performing quality control for nucleic acid sample sequencing is disclosed. The system has a set of solid supports, each support having attached thereto a plurality of nucleic acid sequences. The set has plural groups of solid supports and each group contains solid supports having the same nucleic acid sequences attached thereto. The nucleic acid sequences of each group differ from each other. The nucleic acid sequences are synthetically derived. A method of preparing a quality control for performing nucleic acid sample sequencing and a method of validating a nucleic acid sequencing instrument are also disclosed.
