circRNA Research

abm is the leader in circRNA research and product development. This emerging technology has garnered abm a niche spotlight with circRNA researchers around the world. Our comprehensive product line offers circRNA over-expression vectors, purification kits and enzymes including our unique RNase R enzyme. 
circRNAs can be over-expressed in mammalian cells by using non-repetitive regions of reverse complementary sequences - these work to bring the exon-flanking portion of introns in close proximity, thus promoting back-splicing into circRNA. abm offers a collection of over 1000 circRNA over-expressing vectors. These circRNAs have been associated with human disease and can be used in over-expression studies to investigate new roles of circRNA in health.
