Bacterial small RNA-Seq is a method to comprehensively detect small RNAs based the next-generation sequencing (NGS). It can accurately reveal the complete picture of the transcriptome in a biological sample under specific conditions. We provide bacterial small RNA-seq to help you analyze microRNAs (miRNAs), small interfering RNAs (siRNAs), piwi-interacting RNAs (piRNAs), small nucleolar RNAs (snoRNAs) and small nuclear RNAs (snRNAs) at one time.
Small RNA is a type of non-protein-coding RNAs that is short in length (<200 nt). Small RNA species generally include miRNA, siRNA, and piRNA, snoRNA, snRNA and so on. Small RNA populations and abundance can vary significantly among different species and tissue types. Generally, small RNAs are formed by fragmentation of longer RNA sequences with the help of biomolecules, such as the dedicated sets of enzymes. Small RNAs perform many biological functions. For example, miRNAs and siRNAs play an important role in post-transcriptional regulation of gene expression. Small RNAs are involved in a number of biological processes including cell proliferation and differentiation, development, and apoptosis.
Bacterial small RNA sequencing (RNA-seq) isolates small RNAs by size fractionation using silica spin columns or gel electrophoresis selection from total RNA, followed by RNA adapter ligation using a 5’ adenylated DNA adapter with a blocked 3’end. Subsequently, small RNAs are reversely transcribed, amplified by PCR and sequenced. Our bacterial small RNA-seq service can obtain a premium small RNA sequencing library, enabling profiling of small RNAs, detection of mutations/variants/isoforms, functional analysis, prediction and characterization of novel small RNAs, and differential expression analysis.

Sample Storage: RNA can be dissolved in ethanol or RNA-free ultra-pure water and stored at -80°C. RNA should avoid repeated freezing and thawing.
Shipping Method: When shipping RNA samples, the RNA sample is stored in a 1.5 mL Eppendorf tube, sealed with sealing film. Shipments are generally recommended to contain 5-10 pounds of dry ice per 24 hours.
