Small RNA & miRNA Sequencing on the 5500 Genetic Analyzer
Small noncoding RNAs are typically only ~18–40 nucleotides in length, but their effects on cellular processes are profound. Small RNAs have been shown to play critical roles in developmental timing, cell fate, tumor progression, and neurogenesis.
Animals, plants, and fungi contain several distinct classes of small RNAs, including:
Small RNA Analysis With the 5500xl Genetic Analyzer
The SOLiD® Small RNA Solution is a robust method for hypothesis-neutral, whole genome analysis of expression patterns that enables you to discover novel RNA without the probe bias of microarrays. Using the SOLiD® Total RNA-Seq Kit, you can convert total RNA into a library in a single day. This simplified protocol reduces experimental variability and improves the detection of biologically relevant changes.
The SOLiD® Total RNA-Seq kit is a single kit for the construction of libraries either for small RNA or whole transcriptome analysis.
Together, the SOLiD® Total RNA-Seq Kit and the ultra–high-throughput 5500xl Genetic Analyzer:
- Conserve strand specificity of cDNA—allowing you to know exactly which strand a particular small RNA originated from
- Offer better sensitivity—high number of mapped reads coupled with the accuracy of exact call chemistry (ECC) give confidence in detecting rare and low-abundance small RNAs
- Offer versatile inputs—analyze small RNAs from a variety of sample types, including quality compromised samples, such as RNA from FFPE tissue, starting with as little as 5 ng Learn More
- Detect novel RNAs—facilitate detection of unmapped small RNAs and isoforms
- Allow multiplexing—sequence multiple small RNA libraries simultaneously in a single lane, helping to reduce the cost of analysis per sample
Step-by-Step Guide to Small RNA Analysis
Determine the level of sensitivity you need and the number of samples you want to analyze. Internal research conducted at Applied Biosystems suggests 10 million mappable sequences are needed for profiling known miRNAs in humans. Other organisms with similar sized genomes are expected to require a similar number of mappable sequences. It is not known at this time how many mappable sequences may be necessary to confidently discover new species of small RNAs.
