5-Formyl-dC has garnered recent interest as a key step in a proposed demethylation pathway via oxidation of 5-Me-dC http://ow.ly/bJzXP
Site-directed or oligonucleotide-directed mutagenesis is a key method in the study of protein structure/function and gene expression control. If the nucleotide sequence of the gene is known, an oligonucleotide can be manufactured to introduce a single base change in the codon corresponding to the specific amino acid to be altered. The oligonucleotide is then used to generate a set of clones that can be identified and propagated. Learn More.
While randomers are often used in protein mutagenesis procedures, they have several short comings. First, it is very difficult to achieve a truly random mixture. The second and more problematic issue is the inevitable introduction of stop codons. Fortunately, the ability to direct combinatorial mutagenesis using randomized oligonucleotides has been advanced by the use of trimer oligonucleotides. Read More.
Wondering which RNA polymerase to use for incorporation of 2′ Fluoro and 2′ O-Methyl NTPs? We recommend T7 R&DNA™ and SP6 R&DNA™ polymerases from Epicentre. We’d like to hear from you – click the link below to leave your comment.

Thank you Prithwish for your most recent question regarding the synthesis of very long oligonucleotides. We know research is in need of longer and longer synthetic oligonucleotides and have been working to push through current synthesis barriers. Thus far, we have succeeded in producing high quality DNA 180mers and RNA 100mers. We are continuing to push these limits. Learn more in our January Newsletter.
