Long DNA Oligonucleotides Synthesis

Long DNA oligonucleotides can be used in various molecular biology applications, including: cloning, gene construction and site-directed mutagenesis, shRNA library preparation, SNP synthesis positive control template for qPCR, targeted resequencing, etc. Generally, the longer the oligonucleotide, the more difficult it is to synthesize, which is an inevitable fact, and the failure sequence increases as the length of the oligonucleotide increases, and it is impossible to obtain a pure oligonucleotide. Therefore, it is very important to synthesize high-quality long oligonucleotides, which will help promote the development of molecular biology.
