ABSTRACT
Objective To establish an auto-control system for high-throughput and multi-channel DNA synthesis which can simultaneously and quickly synthesize up to 96 different oligonucleotides in a 96-well microtiter format.Methods The PLC and its extended modules is used as the main-control unit, which executes the DNA automatic synthesis process according to the synthesis sequences and steps set by the user,and the manual injecting reagent etc.And the configuration software and VC6.0 were used for programming the man-machine interface sofeware to set synthesis parameters, position calibration,flux calibration data etc, and communicated with PLC.Results The synthesis application of about 150 000 DNA chains has proved that the synthesis cycle time for 96 couplings was 4 min,the average coupling efficiency was 99%across the entire 96-well plate,the monomer reagent usage was reduced by 50 percent,and the synthesis configuration was more flexible.Conclusion A reliable and simple auto-control system is provided for parallel synthesis of 96-channel oligonucleotide chains,which can meet the demands of high-throughput and multi-channel DNA synthesis.
