QIAseq FastSelect –5S/16S/23S Kits use a novel method to remove highly abundant bacterial 5S/16S/23S rRNA from your RNA-seq library. QIAseq FastSelect –5S/16S/23S was specifically designed for complex community microbial samples from soil, water, stool and sludge, which have numerous and diverse bacterial populations. The rRNA coverage provided by this kit is based on SILVA 16S sequences (nearly 600,000 entries), SILVA 23S sequences (nearly 170,000 entries) and 5S rRNA database sequences (over 7200 entries), and in-silico modeling shows coverage of >95% of all known 5S, 16S and 23S rRNA sequences.

QIAseq FastSelect –5S/16S/23S has been tested with QIAGEN, Illumina and NEB RNA-seq library kits and is compatible with all major methods of RNA-seq library preparation. The simple 14-minute protocol and bead cleanup integrates seamlessly with all common RNA-seq library kits, and can be used on fragmented or full-length (non-fragmented) RNA.

For removal of human, mouse, rat and other mammalian rRNA, please see our QIAseq FastSelect –rRNA HMR Kits.

Used after bacterial RNA extraction, QIAseq FastSelect –5S/16S/23S is a pan-bacterial rRNA removal kit designed to remove 5S, 16S and 23S rRNA from complex bacterial community samples. Our comprehensive rRNA removal reagent has been designed using 16S (nearly 600,000 entries), 23S (nearly 170,000 entries) and 5S rRNA sequences (over 7200 entries). In-silico modeling predicts >95% rRNA removal of all known 5S, 16S and 23S rRNA sequences.

QIAseq FastSelect –5S/16S/23S can accommodate RNA amounts ranging from as little as 20 ng to 1 µg, with consistently high performance, and is compatible with low-quality, highly fragmented or high-quality full-length RNA. Since QIAseq FastSelect –5S/16S/23S does not use enzymatic digestion or hybrid-capture procedures, the fast, simple workflow results in reliable rRNA removal and high reproducibility in downstream applications.

Most RNA removal or depletion strategies associated with RNA-seq library construction are sample pre-treatments involving hybrid-capture or enzymatic removal of unwanted RNA. Our unique QIAseq FastSelect procedure is significantly faster and is compatible with most RNA-seq library kits. QIAGEN FastSelect –5S/16S/23S has been tested with QIAGEN, Illumina and NEB stranded RNA-seq library kits.

QIAseq FastSelect –5S/16S/23S seamlessly integrates with your existing RNA-seq library preparation, providing RNA removal in a single, 14-minute step, which is followed by bead cleanup (figure  QIAseq FastSelect –5S/16S/23S workflow). Prior to RNA heat fragmentation (which is optional and dependent upon the library preparation kit and sample type), QIAseq FastSelect –5S/16S/23S removal reagent is directly combined with total RNA and fragmentation buffer. After optional fragmentation, the reaction temperature is stepwise cooled from 75°C to 25°C over 14 minutes, followed by a bead cleanup. The RNA is then ready for reverse transcription. This is dramatically faster than other RNA depletion methods, which require more than 25 steps and approximately 2 hours to complete (figure  Bacterial rRNA depletion: alternative products vs. QIAseq Fast Select –5S/16S/23S).

QIAseq FastSelect –5S/16S/23S delivers rapid, reliable rRNA removal for bacterial isolates, as well as complex bacterial communities.
