The concentrations listed are necessary for speedy processing and investigators should plan on providing at least 2X the volume requirements for each sequencing reaction. Supplying extra template will ensure that sufficient material is on hand if it is necessary to re-run a reaction.

Quality
For optimum results, good quality template is essential. For sequencing, the investigator is expected to provide template samples with A260/A280 of 1.8-2.0. We can include a template quality check as a custom service prior to beginning the process. If quality is insufficient, the investigator will be notified.

Template Preparation, Quality, and Quantity Requirements

Important: All samples must be labeled with the sample name, date, and user account number. All samples must be accompanied by a sequencing request form indicating the appropriate Requested sequencing service.
