2012 Cold Spring Harbor Protocols  
This protocol details the process of small RNA cloning for sequencing on the Illumina/Solexa sequencing platform, but it can be easily modified for use on other next-generation platforms (e.g., SOLiD, 454). This procedure is designed to clone canonical small RNA molecules with 5 ′ -monophosphate and 3 ′ -hydroxyl termini. Modifications, such as the presence of a 2 ′ -O-methyl group, can reduce efficiency, although not sufficiently to negate the utility of the approach. Other termini

MATERIALS It is essential that you consult the appropriate Material Safety Data Sheets and your institution's Environmental Health and Safety Office for proper handling of equipment and hazardous materials used in this protocol.
