Sanger sequencing, next generation sequencing (NGS), long read sequencing, and fragment analysis each enable a variety of applications across a broad range of research areas. Both Sanger sequencing and fragment analysis use capillary electrophoresis (CE) for separation and detection. The method of choice depends on your application and throughput.
Sanger sequencing is ideal for small-scale projects focusing on one or two genes, while NGS is ideal for higher-throughput sequencing needs. Long read sequencing is useful for the discovery of large unknown variants. Although fragment analysis does not provide sequence information, it is a simple and accurate method used to generate relative quantitation information in a cost-effective manner due to its high resolution and multiplexing capability.
Here are some things to consider when deciding the right sequencing method for your needs:

Fragment analysis |
Fragment analysis leverages the single base resolution of CE to detect hundreds of targets per reaction. It is useful for many applications, including:
|
Both Sanger sequencing and fragment analysis utilize capillary electrophoresis to provide simple, sample-to-answer workflows for highly accurate sequence interrogation and fast turnaround time.
