On occasion researchers have developed special modified bases or simply have ideas of modified bases that they wish to be incorporated in oligos. Gene Link routinely collaborates extensively with investigators. We assist in the design of oligos with special modification to impart specific characteristics. We also incorporate investigator supplied modified bases and fluorescent dyes in oligos. If it is simply an idea then we collaborate with other labs and companies for the synthesis of these novel modified bases.
