ExperimentRNASynthesis[OligomerModels]⟹Protocol

creates a RNA Synthesis Protocol to synthesize the OligomerModels.

    
Ribonucleic acid (RNA) synthesis is the process of creating RNA strands of a desired sequence via solid-phase synthesis. RNA created in this way is constructed by molecules known as phosphoramidites, which are made up of a single nucleobase and nucleic acid backbone, as well as protecting groups that are removed at specific stages throughout the synthesis process. During this process, synthesis cycles made up of a series of chemical reactions are repeated, each time adding a single nucleobase to a growing oligomer. During each cycle, the specific nucleobase added to the reaction can be controlled, providing the ability to create arbitrary RNA sequences. Synthesis begins with a large, immobile support, often controlled pore glass (CPG). Attached to each support is a chemical linker that provides the first nucleobase added to the reaction a location to bind. By manipulating orthogonal chemistries, one nucleobase is added to the end of the growing oligomer during each synthesis cycle, leading to specific control over the sequence created. The benefit of the solid support is the isolation of synthesis sites, making interference between growing chains impossible. Having target oligonucleotide attached to solid support allows for the use of high excess reagents, which drives the reaction efficiency to high percentiles, providing stepwise yields. This attachment also simplified purification, allowing any excess of materials to be washed off while the target sequence stays attached to the support. After the desired sequence has been synthesized, a cleavage reaction is conducted to strip the fully grown RNA strands from their solid supports by severing the chemical linker as well as removing protective groups from the nucleobases. These solid supports are then filtered away from the nucleic acid material yielding oligomers of desired sequences. As opposed to DNA synthesis, RNA synthesis requires an additional deprotection step to remove the extra protecting group from the 2'-hydroxyl on the backbone after cleavage.
    

Experimental Principles

    Figure 1.1: General scheme of the synthesis of RNA. Step 1: first monomer is loaded on the solid support. Step 2: subsequent monomers are loaded on the solid support, extending the length of the RNA though repeating the synthetic cycle. (A) Deblocking - removal of the DMT protecting group from the growing end (5' end) of the RNA strand with trichloroacetic acid, allowing for the coupling of the next base in the sequence. (B) Adding (coupling) the next monomer in sequence to the exposed 5' end of the RNA strand. Before the monomer can be coupled, the diisopropylamino protecting group on the 3' phosphorous must be removed and replaced with a good leaving group, this achieved through the addition of the activator to the reaction mixture. Since the new monomer has its own DMT protective group on the 5' oxygen, only one coupling can happen per each strand. (C) Capping unreacted strands. Even though the coupling efficiency is high, it is possible that some of the strands will not be coupled to the strand on the solid support, leaving 5' hydroxy group available for the next coupling. In order to make those strands passive, they are reacted with the acid anhydride. (D) Oxidation of the tricoordinated phosphate triester linkage connecting the last two bases of the growing oligomer to form tetracordinated phosphate triester linkage using iodine, water and a weak base. Step3: RNA strands are cleaved from the solid support and protecting groups on the bases are removed using strong base solution like Ammonia in water. Step 4: removal of the protecting group from the 2'-hydroxy group. The most widespread protective group for 2'-hydroxy group (TBDMS) use solutions containing fluoride ions to selectively remove it from the RNA strand.

Instrumentation

    ABI 3900

    Figure 2.1.1: Columns containing solid supports, likely CPGs, are loading into the synthesizer deck in positions 1 through 48. There are four banks of columns, each holding 12 columns in place. Reagent bottles are attached to their appropriate loading positions prior to the start of the run. Most reagents are loaded in duplicate, with one set of reagents supplying the injection lines used by banks 1 and 3 and the other set supplying the injections lines of banks 2 and 4. In addition to the standard synthesis reagents, there are 6 positions for ‘modifier’ phosphoramidites, which can be injected into all banks and provide the ability to add non-standard bases or modifications to your synthesized oligomers.     The entire system is plumbed with argon gas, which floods the synthesis chamber as well as the headspace of the reagents, as the reagents are water and oxygen sensitive. The argon pressure above the reagents provides positive pressure, which is used to push reagents through the injection lines. Injections are controlled via the opening or closing of a solenoid value at the end of each reagent injection line. During synthesis, reagents are injected into each column during each stage of the synthesis cycle. In between injections, the chamber is further pressurized by argon gas and a waste valve is opened below the synthesizer deck. This causes any fluid reagent in the columns to be flushed out of the system into waste, while the growing oligomer strands remain attached to the solid supports sandwiched between two frits in each column.     Once synthesis is complete, the columns are removed from the chamber and shuttled off to a cleavage and filtration station, where the oligomers are cleaved from the deck. The synthesizer meanwhile undergoes a system flush with acetonitrile to remove any sticky reagents that would otherwise harden and clog injection lines. Placeholder bottles are then placed on the instrument, each with a large volume of acetonitrile, such that the synthesizer remains water-free in between synthesis experiments.

    Modifications

    Any modifications that will be used for the synthesis can be directly added to the strand Model. For any novel modifications, you can directly specify the monomer solution with the Monomers Option. For example, here we perform one synthesis with a common modification (automatically selecting the Monomer), and another synthesis with a novel modification that has a monomer solution specified:

    Control the supports used to begin synthesis:

    Manually specify the columns to use in the synthesis:

    Control cleavage conditions used at the end of the protocol:

    Specify a cleavage method that will set the solution, time, and temperature for cleavage:
    Specify cleavage parameters for your samples:
    Specify that no cleavage should be conducted and your SamplesOut with RNA still bound to their solidphase supports:

    Make sure that the Model[Sample] for the phosphoramidite has FixedAmounts (how much is in the bottle) and TransferOutSolventVolumes (how much solvent we will add to make a StockSolution) set:
    Create a new Model[Sample, StockSolution] for the phosphoramidite of the given concentration. This special form of StockSolution definition will have the StockSolution be prepared in the original container of the Sample that has FixedAmounts populated. Additionally, we specify how we will mix out mixture to dissolve phosphoramidite:

Possible Issues

    SamplesOut Mass

    The mass of cleaved synthesized oligos is estimated to be half the product of the synthesis scale and the oligo's molecular weight. It is highly recommended to quantify synthesized oligos by ExperimentAbsorbanceSpectroscopy.
