An elegant and simple workflow for RNA enrichment
Unmatched enrichment levels:
Identify ribonucleoprotein complexes:
The identification of the compositions of ribonucleoprotein complexes (RNPs) formed by a specific transcript is of great value in RNA studies. It is, however, a challenging task, and is difficult to accomplish with a classic toolbox of biochemical methods. Such studies can be performed on lysates of UV cross-linked cells with sequence-specific target capture utilizing antisense oligonucleotides. Typically systems based on biotinylated oligonucleotides complementary to the sequence of the transcript of interest in combination with streptavidin beads are employed. Proteins co-captured in such procedures can be identified by mass spectrometry.
Directly from cellular or tissue lysates:
MagIC Beads based systems for the study of RNA-protein interactome feature exceptionally efficient hybridization based approach of sequence specific RNP captures free of the weaknesses and shortcomings of biotin-streptavidin based workflows.
The kits consist of the target-specific MagIC Beads and sets of optimized buffers. They feature standardized cell lysis and capture conditions as well as capture probes properties, which ensure uniformly high efficiency of the system on varying RNA targets, independently of their length or secondary structures. The beads provide very high target capture efficiency and enrichment levels.
For any custom target transcript the optimal number of probes is established based on the target length and nucleotide composition. Experimentally validated design approach is used to provide uniformly highly efficient capture probe arrays for any target. Every probe is extensively screened against potential binding to any off-targets in the transcriptome of interest to ensure superb probe specificity.
Downstream application agnostic:
The enrichment method is downstream application agnostic and the proteins co-captured with the target RNA can be subjected to analysis with various methods, including:
‣ Mass spectrometry
‣ Western blotting
‣ Silver staining on a protein gel
Compared to classic biotinylated probe-based approaches, MagIC Beads provide multiple benefits:
| No probe design burden | Reliable arrays of capture probes are designed by ElementZero Biolabs for any target |
| Reliable performance: No need for RNA fragmentation | Efficient capture regardless of the target length or the presence of secondary structures |
| No sequence capture biases | Full length target transcripts are captured, including fragments of the target not covered by probes |
| No chromatin fragmentation needed: sonication or DNases not necessary | Full-length genomic DNA is not co-captured by the beads |
| Reduced experimental background due to stringent capture conditions | Reduced capture of non-target transcripts and molecules not cross-linked to the target transcript |
| No background from naturally biotinylated molecules | MagIC Beads do not capture non-target biotinylated molecules from the sample |
| Significantly lower costs | RNase inhibitors, DNases, streptavidin beads or additional buffers are not required |
| Preserved target integrity | During the enrichment, nucleases are inactivated by the buffers (no need for RNase inhibitors) |
| Fast and simple protocol | The enrichment procedure can be completed in 1-2h with a reduced number of hands-on steps |
| No need for additional key components of the experimental setup | MagIC Beads enrichment kits are provided as complete, out of the box solution |
| Expert support | Count on active support regarding the use of the kit as well as analysis of planned downstream applications |
