miScript miRNA PCR Arrays

miScript miRNA PCR Arrays are mature miRNA-specific forward primers (miScript Primer Assays) that have been arrayed in biologically relevant pathway-focused, disease-focused, or whole miRNome panels. miScript miRNA PCR Arrays are part of the miScript PCR System for miRNA detection and quantification. cDNA is prepared using the miScript II RT Kit with miScript HiSpec Buffer and is used as a template in real-time PCR with a miScript miRNA PCR Array and the miScript SYBR Green PCR Kit.

Important note: This product line will be discontinued on May 1, 2021 and will be replaced by the miRCURY LNA miRNA PCR system. We strongly recommend using the following miRCURY LNA PCR products for better miRNA quantification and profiling: miRNome PCR Panels, miRNA Focus PCR Panels and miRNA QC PCR Panel.

Discover biomarkers in serum or plasma samples

The range of pathway-focused miScript miRNA PCR Arrays is continually expanding to enable new discoveries about the roles of miRNAs in biological processes. The content of miScript miRNA PCR Arrays is selected using our proprietary methodology, which ensures that each array is up-to-date and biologically relevant. One of the most exciting areas of current miRNA research involves the assessment of miRNAs present in serum or plasma samples. The discovery of relatively stable, extracellular miRNAs in serum and plasma has generated huge interest in the use of changes in these miRNA levels as potential noninvasive biomarkers for a variety of diseases. As a result, the Serum & Plasma miScript miRNA PCR Array has been developed. This array enables rapid profiling of the 84 most relevant miRNAs associated with serum and plasma (see figure " Analysis of expression of circulating miRNAs in serum or plasma").

Profile entire miRNomes with a single cDNA sample

In addition to pathway-focused arrays, up-to-date miRNome miScript miRNA PCR Arrays are available for a variety of species including human, mouse, rat, dog, and rhesus macaque. With less than 1 µg RNA, the entire human miRNome can be rapidly profiled (see figure " Whole miRNome profiling"). Each assay in a miScript miRNA PCR Array has been bench verified to ensure sensitive and specific detection of mature miRNA by real-time PCR.

The miScript PCR System enables sensitive, specific miRNA quantification and profiling using SYBR Green real-time PCR. The miScript PCR System covers all the steps involved in conversion of RNA to cDNA and subsequent real-time PCR detection of miRNAs.

Mature miRNA profiling with the miScript PCR System uses the following components:

• miScript II RT Kit — this kit enables simple, single-step cDNA synthesis. A single cDNA synthesis reaction can be used for detection of hundreds of miRNAs. The dual buffer system meets the distinctive needs of miRNA quantification using real-time PCR.
• miScript SYBR Green PCR Kit — this kit includes QuantiTect SYBR Green PCR Master Mix and the miScript Universal Primer, a reverse primer that allows detection of miRNAs in combination with a miScript Primer Assay or miScript miRNA PCR Array.
• miScript miRNA PCR Array — Cutting-edge miScript miRNA PCR Arrays consist of mature miRNA-specific forward primers (miScript Primer Assays) arrayed in biologically relevant pathway- or disease-focused panels or miRNome panels.

miRNA expression profiling with miScript miRNA PCR Arrays is straightforward and robust. First, prepare cDNA buffered with miScript HiSpec Buffer using the miScript II RT Kit. Second, add a premix of cDNA, miScript Universal Primer, QuantiTect SYBR Green PCR Master Mix, and RNase-free water to a miScript miRNA PCR Array. Third, run the reaction in a real-time PCR cycler. Finally, analyze the data using the miScript miRNA PCR Array Data Analysis Tool.

miScript miRNA PCR Array plate layout

miScript miRNA PCR Arrays are available in 96-well, 384-well, and Rotor-Disc 100 formats (see figures " Pathway-Focused or miRNome miScript miRNA PCR Array layout for plate formats A, C, D, F, M", " Pathway-Focused miScript miRNA PCR Array layout for plate formats E, G", " miRNome miScript miRNA PCR Array and miScript miRNA HC PCR Array layout for plate formats E, G", and " miScript miRNA PCR Array layout for Rotor-Disc format R"). Each array contains several control assays. The purpose of these assays is described in the table below.

For more information on these controls, consult the miScript miRNA PCR Array Handbook.

miScript miRNA QC PCR Array plate layout

miScript miRNA QC PCR Arrays enable assessment of the quality of multiple cDNA samples using real-time PCR. miScript miRNA QC PCR Arrays are available in 96-well, 384-well, and Rotor-Disc 100 formats (see figures  miScript miRNA QC PCR Array layout for plate formats A, C, D, F,  miScript miRNA QC PCR Array layout for plate formats E and G, and " miScript miRNA QC PCR Array layout for Rotor-Disc format R"). Each miScript miRNA QC PCR Array includes replicates of C. elegans miR-39 miScript Primer Assay, 3 mature miRNA miScript Primer Assays (miR-16, miR-21, miR-191), 3 snoRNA miScript Primer Assays (SNORD61, SNORD95, SNORD96A), miRTC miScript Primer Assay, and a positive PCR control. For more information, consult the miScript miRNA PCR Array Handbook. The 96-well plate and Rotor-Disc 100 formats allow quality control of up to 8 cDNA samples. The 384-well format allows quality control of up to 32 cDNA samples.

miScript miRNA PCR Array Data Analysis Tool

Free, easy-to-use data analysis software is available online for miScript miRNA PCR Arrays. Each miScript miRNA PCR Array comes with a dedicated data analysis tool. Once raw C_T values are entered, the analysis tool automatically interprets the PCR array controls, performs relative quantification using the ∆∆C_T method, and presents the results in a variety of visual formats, allowing you to rapidly interpret your data.

miScript miRNA PCR Arrays are used as part of the miScript PCR System for:

• Pathway- and disease-focused miRNA profiling
• miRNome profiling
• Biomarker discovery
