The importance of a good start
miRNA qPCR is the most commonly used technique for miRNA expression profiling. There are many advantages of using PCR: it is fast, sensitive and accurate. However, successful qPCR experiments depend on high-quality input RNA. Degraded RNA decreases the efficiency of the technique, and inhibitors can adversely affect the cDNA synthesis and amplification steps. For some samples, such as biofluids, determining the quality of the purified RNA can be difficult.
The miRCURY LNA miRNA QC PCR Panel offers a unique and comprehensive way to check your sample quality and PCR efficiency. The panel contains LNA-enhanced PCR primer sets that target miRNAs and spike-ins that can be specifically used for RNA quality control. These primer sets have been selected based on our extensive experience in miRNA qPCR and analysis of millions of datapoints.
When used in conjunction with the RNA Spike-in Kit, the panel can help you find differences in RNA yield and identify outlier samples (see figure Quickly identify outlier RNA samples). In addition, RNA spike-ins can be used to check the cDNA synthesis and PCR amplification efficiencies.
The miRCURY LNA miRNA QC PCR Panel contains assays for miRNAs that are expressed in a wide range of sample types and is therefore suitable for evaluating the samples in a biological context. Two of the miRNAs in the panel can be used to evaluate the level of hemolysis in samples such as serum and plasma.
Product coverage
The miRCURY LNA miRNA QC PCR Panel consists of 12 predefined assays for use in human, mouse, rat, monkey and dog samples (see figure Panel layout and table miRCURY LNA miRNA QC PCR Panel coverage). The panel can be used for assessing RNA from a wide variety of samples, including tissue, cell culture and biofluids.
The panel is available in two formats:
- 96-well, ready-to-use: two 96-well PCR plates containing 16 miRNA QC panels; compatible with most real-time PCR instruments.
- 384-well, ready-to-use: one 384-well PCR plate containing 32 miRNA QC panels; compatible with most real-time PCR instruments.
The plates are produced in a ready-to-use format, which means that the primer sets are dispensed and lyophilized in the well in an amount sufficient for one 10 µl reaction per well.
