Row-independent oligonucleotide synthesis
Apparatuses and a method for plate-based oligonucleotide synthesis are disclosed. In one example, an apparatus used in oligonucleotide synthesis includes a machined block to receive a commercially-available synthesis plate. A keeper is used to apply pressure to the commercially-available synthesis plate, and a sealing element is used to seal the commercially-available synthesis plate to the machined block. Other methods and apparatuses are disclosed.
