Cerebrospinal Fluid MicroRNA Profiling Using Quantitative Real Time PCR

Overview

This protocol describes the use of real-time PCR to profile microRNAs in cerebrospinal fluid (CSF). The method can also be adapted for RNA extracted from other body fluids, cultured cells, or tissue specimens.

Key Study Components
