Abstract
Concentrated, intact, and biologically-active DNA templates are essential for protein production using cell-free expression. We present automated methods for DNA template preparation and quantitation towards improving reproducibility in cell-free expression.
The following automated methods for DNA template preparation and quantitation were developed for improving reproducibility in cell-free expression and are described in detail elsewhere.

These methods were developed using the Hamilton STAR automated liquid handler with the Monitored Multi-Flow Positive Pressure Evaporative Extraction ([MPE]2) module. For questions about methods or implementation, contact Jane Romantseva (eugenia.romantseva@nist.gov).
