Extendamers™ are oligonucleotides from 130 - 200 bases. Bioneer specializes in long oligo synthesis and provides them with Bio-RP or PAGE purification. As with all Bioneer Oligonucleotides, Extendamers are QC tested by MALDI-TOF after oligo synthesis, ensuring the highest quality products for your research needs. Bio-RP (or PAGE) purification also ensures you have only full length oligonucleotides for your experiments. Use Extendamers for cloning, mutagenesis and other demanding applications.
