The NEBNext Multiplex Small RNA Library Prep Kit for Illumina (Index Primers 1-48) contains the adaptors, primers, enzymes and buffers required to convert small RNAs into indexed libraries for next-generation sequencing on the Illumina platform. The novel workflow has been optimized to minimize adaptor-dimers, while producing high-yield, high-diversity libraries. Please note that this kit, the NEBNext Small RNA Library Prep Set for Illumina (Multiplex Compatible), enables use with your own barcode system. This kit contains adaptors but does not include multiplex primers.
