With the state-of-art instruments and professional staffs, Creative Biolabs has over a decade of working experience in next-generation sequencing (NGS). Based on our powerful SuPrecision™ platform, Creative Biolabs is proud to offer you with the circRNA sequence information with single-base resolution. We can provide the most comprehensive bioinformatics analysis, including circRNA identification and annotation, known circRNA, novel circRNA prediction, origin analysis of circRNA and target prediction. We are pleased to use our extensive experience and advanced platform to offer the best service to satisfy each demand from our customers.

The Introduction of CircRNA

CircRNA, an addition to the growing list of types of non-coding RNA, is a large group of RNA family extensively existes in cells and tissues. CircRNAs can arise from exons (exonic circRNA) or introns (intronic circRNA). Although the existence of circular transcripts has been known for at least 20 years, such molecules were long considered molecular flukes—artifacts of aberrant RNA splicing or specific to a few pathogens, such as the Hepatitis δ virus3 and some plant viroids. However, potential functions in the regulation of gene expression are emerging for both exonic and intronic circRNAs. Recent work has revealed large numbers of circRNAs that are endogenous to mammalian cells, and many of these are abundant and stable. Circular RNAs, unlike miRNAs and other small RNAs, are not easily separated from other RNA species by size or electrophoretic mobility. Commonly used molecular techniques require amplification and/or fragmentation destroy circularity, however, because of the lack of free 3’ or 5’ end, circRNAs cannot be found by molecular techniques that rely on a polyadenylated free RNA end. The advent of high-throughput NGS provides a promising way to view circRNAs across different samples, especially in cancers.
