GenEZ™ ORF Clones

GenEZ™ ORF Clones makes it easy to order customized expression-ready ORF clones from the world's largest commercial ORF clone database. GenEZ™ ORF clones accelerate your biological research by providing sequence-verified cDNA clones in your choice of expression vector. Unlike off-the-shelf cDNA clones from other companies, GenScript's ORF Clone service lets you specify the cloning site and add up to 30bp of flanking sequences to the 5' and 3' ends of your ORF RefSeq. Choose from over 100 popular commercial vectors including mammalian and bacterial expression vectors or standard cloning vectors or shuttle vectors. GenEZ ORF Clones start at just $99/clone and 5-day turnaround time, with delivery of 10μg sequence-verified plasmid DNA.
