A Morpholino, also known as a Morpholino oligomer and as a phosphorodiamidate Morpholino oligomer (PMO), is a type of oligomer molecule (colloquially, an oligo) used in molecular biology to modify gene expression. Its molecular structure contains DNA bases attached to a backbone of … See more Morpholino oligos were conceived by Summerton (Gene Tools) at AntiVirals Inc. (now Sarepta Therapeutics) and originally developed in collaboration with Weller. See more Morpholinos do not trigger the degradation of their target RNA molecules, unlike many antisense structural types (e.g., phosphorothioates, siRNA). Instead, Morpholinos act by "steric blocking", binding to a target sequence within an RNA, inhibiting … See more For a Morpholino to be effective, it must be delivered past the cell membrane into the cytosol of a cell. Once in the cytosol, Morpholinos freely diffuse between the cytosol and … See more • Wiley-Liss, Inc. Special Issue: Morpholino Gene Knockdowns of genesis Volume 30, Issue 3 Pages 89-200 (July 2001). This is a special issue of … See more Morpholinos are synthetic molecules that are the product of a redesign of natural nucleic acid structure. Usually 25 bases in length, they bind to complementary sequences of RNA … See more Morpholinos have become a standard knockdown tool in animal embryonic systems, which have a broader range of gene expression than adult cells and can be strongly affected … See more • Oligonucleotide synthesis • Nucleic acid analogue See more WebMay 21, 2009 · Preparation of the Solid Support for Synthesis of Morpholino Oligomers Example 4a Preparation of Aminomethylpolystyrene-disulfide resin [0124]This procedure was performed in a silanized, jacketed peptide vessel (custom made by ChemGlass, NJ, USA) with a coarse porosity ...
