A new generation of miRCURY LNA™ microRNA arrays for expression profiling of microRNA from human, mouse, and rat are now available. The new microRNA arrays have 2,361 unique capture probes covering all mature human (1,223), mouse (1,055), rat (680), and related viral (human 146, mouse 57) microRNA sequences as annotated in miRBase v16.0. The array also contains capture probes for 66 miRPlus™ microRNAs. The miRCURY LNA microRNA Array, 6th generation - hsa, mmu, & rno microarray requires sample input of 30 ng of total RNA. It is possible to detect down to 10 copies of microRNAs from a biological sample. A labeling kit is available for use with the arrays to obtain higher sensitivity.
