| Description | In Vivo SHAPE Reagent for Live Cell RNA Structure Analysis |
| Overview | Features & Advantages
In Vivo SHAPE Reagent is used for the determination of RNA structure. This reagent contains a highly pure form of 2-methylnicotinic acid imidazolide (NAI). This compound forms 2’-O-adducts on single stranded regions of RNA that can be detected by Selective 2’-Hydroxyl Acylation and Primer Extension (SHAPE). In contrast to other reagents used for the SHAPE method, the NAI–based In Vivo SHAPE Reagent is rapidly absorbed into cells and is formulated to have low levels of toxicity making it ideal for use with live cells. Unlike other reagents used for SHAPE analysis, In Vivo SHAPE Reagent reacts in an unbiased fashion with all four RNA nucleotides. This combination of low toxicity, rapid uptake and lack of nucleotide bias enables high resolution RNA structure analysis in a variety of living systems. |
| Background Information | Folding into higher-order structures allows RNAs to function inside living cells and form dynamic complexes with effector proteins. Predicting these 3D structures is challenging and therefore a number of probing techniques have been developed to study RNA folding. Compounds such as 2-methylnicotinic acid imidazolide (NAI) contained the In Vivo SHAPE Reagent result in the formation of 2’-O-adducts. These adducts form rapidly on single stranded unpaired RNA and much more slowly on based paired (double stranded) RNA. Modified RNA can then be analyzed by primer extension. Modified nucleotides are not extended by RNA dependent DNA polymerases thus allowing sites of modification to be detected. References 1. Wilkinson K., et al. (2006).
