The SMARTer smRNA-Seq Kit for Illumina is used to generate small RNA-seq libraries for sequencing on Illumina platforms. This kit was developed to work directly with total RNA or enriched small RNA (including microRNA), for inputs ranging from 1 ng–2 μg. By incorporating features of the SMARTer Stranded RNA-Seq kits, including our proprietary SMART (Switching Mechanism at the 5' end of RNA Template) technology, and primers that include locked nucleic acids (LNAs), this kit allows users to analyze a wide range of smRNA species and generate sequencing libraries of considerable complexity from as little as 1 ng of input material. Illumina adapter and index sequences are incorporated in a ligation-free manner during library amplification, ensuring that diverse smRNA species are represented with minimal bias.
