Small RNA

What is the optimum read length required for a illumina based small RNA sequencing?

I am planning to pursue a small RNA sequencing project, however, I am a bit under confident in choosing the correct read length for a illumina hiseq based small RNA sequencing. The options that I...

Is anyone familiar with 30 nucleotide peak in small RNA libraries?

I performed an RNA-seq experiment and observed an unusual size distribution of small RNAs (image attached). I was wondering if anyone has seen this before. I used Ambion's mirVana small RNA kit...

Which pipeline or approaches to predict sRNA's in bacteria?

I'm trying to predict some sRNA's (small rna's) which are non-coding rna's in bacteria. I'm following an approach that i have seen in a paper, that uses MAUVE and RNAz to predict them. But the...

Which tools are there to find non-coding RNAs in bacterial RNA-seq data?

I'm looking for tools to semi-automate finding non-coding RNAs in bacterial RNA-seq data. I've been able to find some tools but I'm still quite lost (see link below). I've also seen this Biostar...

What is the best protocol for purifying small RNAs for small RNA-seq in C. elegans?

I have tried to enrich for small RNAs from total RNAs using miRvana kit from Ambion. It definitely got rid of a lot of types of RNAs including abundant rRNAs, but I got enrichment of 90nt size...

How can one modify an RNA oligo to have a 5' triphosphate?

For my project, I need to cap synthetically prepared RNA oligos and most of the capping kits available require a triphosphate group at the 5' end as a substrate. I have looked all over for kits...

Has anyone ever used the miRcode for target prediction?

Has anyone used this http://www.mircode.org/mircode/index.php for target prediction? If so, any comment on how it performs? eg. compared to the usual TargetScan.

Do I really need to DNase treat my small RNA sample before library prep?

I have isolated RNA shorter than 200 nts. On an agarose gel I cannot see any genomic DNA, but this is not very sensitive. I do not want to treat with DNase because I am afraid of three things: 1)...

Working with PCR plates for large-scale preparation of cDNA libraries for sequencing?

Hi, Does anyone have experience with preparing cDNA libraries from small RNA, for next-generation sequencing? If so, has anyone tried doing it in PCR plates instead of strip tubes? I have a large...

Statistical significance of find a certain number of reads in a certain number of bases

I´m working with small RNAs which are produced by transposons, in my data set I have different transposons with different sizes, by chance I expect that transposons with more bases could produce...
