REAGENT EXCHANGE IN AN INSTRUMENT
A method includes flowing an incorporation reagent through a reagent management system and a flow cell of an instrument. The flow cell having a first polynucleotide positioned therein. The incorporation reagent adding a first base onto a sequence of bases. The sequence of bases includes a second polynucleotide complementary to the first polynucleotide. An image of an identification signal emanating from the first base is captured after the first base has been added onto the second polynucleotide. A cleavage reagent is flowed through the reagent management system and flow cell to remove a first terminator from the first base in order to enable a subsequent base in the sequence of bases to be added to the second polynucleotide. A buffer reagent is flowed through the reagent management system and flow cell in a plurality of cycles of consecutive forward and reverse flow directions.
REUSE AND RECYCLING FOR POLYMER SYNTHESIS
Reagents and solvents used for polymer synthesis are reused or recycled rather than discarded. The outflow from each step of polymer synthesis may be collected separately in one of multiple dedicated containers. Reuse returns the outflow from a step of polymer synthesis back to an input of a polymer synthesizer for subsequent use in that same step. Recycling processes the outflow from one or more steps of polymer synthesis to restore original concentrations or purity levels for use in a later synthesis run. Quality control analysis may determine if outflow collected from a polymer synthesizer is reused or recycled. These techniques reduce reagent cost and waste quantity. These techniques may be used with phosphoramidite or enzyme-based synthesis of deoxyribonucleic acid (DNA).
