What is phosphoramidite method?
Phosphoramidite chemistry is the gold standard method for DNA synthesis that has been used in the industry for almost 35 years. Since its discovery, its simplicity and high efficiency have allowed large volumes of oligonucleotide sequences to be synthesized up to 200 base pairs in length.
What is solid-phase oligonucleotide synthesis?
Solid-phase synthesis is widely used in peptide synthesis, oligonucleotide synthesis, oligosaccharide synthesis and combinatorial chemistry. Solid-phase synthesis has a number of advantages over solution synthesis: large excesses of solution-phase reagents can be used to drive reactions quickly to completion.
What is the purpose of capping used at the time of oligonucleotide synthesis?
If not blocked, this reactive group can couple to the nucleotide added in the next cycle, producing an oligo with a deletion in its sequence. To avoid this, a capping step is used to prevent any uncoupled molecules from further extension.
How are genes synthesized?
Unlike DNA replication that occurs in cells or by Polymerase Chain Reaction (PCR), gene synthesis does not require a template strand. Rather, gene synthesis involves the step-wise addition of nucleotides to a single-stranded molecule, which then serves as a template for creation of a complementary strand.
What are oligonucleotides used for?
Oligonucleotides are used as probes for detecting specific sequences that are complementary to the oligonucleotides. When a certain sequence needs to be detected, a complementary oligonucleotide is synthesized in the laboratory.
What is the difference between oligonucleotide and nucleotide?
is that nucleotide is (biochemistry) the monomer comprising dna or rna biopolymer molecules each nucleotide consists of a nitrogenous heterocyclic base (or nucleobase), which can be either a double-ringed purine or a single-ringed pyrimidine; a five-carbon pentose sugar (deoxyribose in dna or ribose in rna); and a …
What is oligonucleotide therapy?
Oligonucleotide-based therapies are advanced novel interventions used in the management of various respiratory diseases such as asthma and Chronic Obstructive Pulmonary Disease (COPD). These agents primarily act by gene silencing or RNA interference.
