eSHAPE Service: SHAPE RNA Structure Probing for Total RNA or Cells provided by you
Obtain NGS-based in vitro or in cellulo SHAPE RNA Structure Probing data through NAI structure probing of your total RNA or cells
eSHAPE total RNA is a method to obtain SHAPE RNA structure probing data for total RNA in vitro or in cellulo using the NAI reagent. eSHAPE total RNA is available as a kit for end user completion, and as a full service offering with results delivered as a data package containing RNA structure information as reactivity values.
• Compare total RNA from different sources to identify regions of RNA folding variability
• Reveal differences in RNA folding across different conditions or due to RNA binding factors
• Extremely deep RNA coverage >10,000X with minimal sequencing depth
• Elevated mutation rates in NAI samples compared to the DMSO control identify RNA positions with high reactivity/unpaired bases
• Reactivity values are predictive of paired and unpaired base status in RNA secondary structure folds
Eclipse Bio´s SHAPE RNA Structure Probing technology on Total RNA measures local RNA flexibility in vitro or in cellulo for prediction of RNA secondary structures.
Selective 2’-Hydroxyl Acylation analyzed by Primer Extension (SHAPE) is a chemical probing method that measures RNA flexibility at single nucleotide resolution. The licensed use of the patented reagent NAI (2-methylnicotinic acid imidazolide) in the RNA probing reaction forms adducts with the free 2′-OH on the RNA backbone in single stranded regions. In contrast to other probing agents, NAI is unbiased and modifies all 4 RNA bases in single stranded RNA regions. The reverse transcription reaction of these adducts induces mutations in the newly formed cDNA at a higher rate than the DMSO control sample. Mutation rates are determined by NGS and calculated for each position of the RNAs. Computing into SHAPE reactivities guides the folding of the RNAs by indicating the pairing status for each position.
