Long Oligos up to 250 mer Gene Link specializes in the synthesis of long oligos with complex base modifications and oligo types. This requires greater than 99.5% coupling efficiency. This can only be attained by using reagents of exacting specifications, optimized protocols and state-of-the-art instruments. Gene Link has perfected and maintains these standards.
