GenScript's GenBrick™ synthesis service provides 100% accurate up to 200 kb long DNA sequences, the fundamental building blocks of synthetic biology. Compared to assembling large DNA constructs from oligos or short DNA segments, which is time-consuming and error-prone, GenScript's GenBrick™ synthesis service delivers full-length synthetic DNA fragments with 100% guaranteed sequence accuracy, free of any mutations or negative clones. Building on our expertise in gene synthesis and molecular biology, GenScript's scientists have developed proprietary technology for accurate and efficient one-step assembly DNA fragments, allowing us to offer the best price and turnaround time available for large synthetic genes: only $0.45/bp and with delivery in as few as 23 business days for custom-synthesized DNA constructs.
