Sequencing by Synthesis
Seq by Synthesis Imagine a small DNA molecule attached to a surface. https://www.cegat.de/en/services/next-generation-sequencing
Seq by Synthesis 1. Add primers https://www.cegat.de/en/services/next-generation-sequencing
Seq by Synthesis 1. Add primers 2. Add free nucleotides 3. Add polymerase https://www.cegat.de/en/services/next-generation-sequencing
Seq by Synthesis 1. Add primers 2. Add free nucleotides 3. Add polymerase 4. Wash 5. Add light and take a photo https://www.cegat.de/en/services/next-generation-sequencing
