QuantiMir RT Kit Overview

What this Kit does:

The new QuantiMir RT Kit tags and converts all small RNAs into cDNA, ready to use as template for real-time qPCR.

  • Measure and profile MicroRNA expression levels from any tissue source

  • Validate the existence of newly discovered MicroRNA species

  • Measure 100 or more different MicroRNAs per QuantiMir RT reaction

  • Detect and quantify siRNAs from knockdown experiments

  • Entire procedure takes <2 hours

  • Kit has enough reagents for 5,000 qPCR experiments
     

    No more messy Northerns or RNase protection assays! Say good-bye to Radioactivity.

    Stop wasting your precious RNA on single MicroRNA detection per RT reaction!
