Shipment condition is checked by ROJETechnologies. After arrival, RNSol reagent should be kept dry, at 2-8 °C and all remaining reagent should be kept at room temperature (15-25 °C). When storage condition is as directed, all reagents are stable until expiration date, as indicated on the kit box.

Intended Use

The MiRJia Kit provides the procedures necessary for purifying total RNA from various sample type. Notice that, MiRJia Kit is intended for molecular biology applications not for diagnostic use.  We recommend all users to study RNA experiments guideline, before starting their work.

Warning and Precautions

Due to chemical material usage that may be hazardous, always make sure to wear suitable lab coat, disposable gloves, and protective eyewear. Material Safety Data Sheet (MSDS) for all products and reagents are provided. They are accessible online at rojetechnologies.com

Quality Control

MiRJia Kit is tested against predetermined experiments on a lot-to-lot basis according to ROJETechnologies ISO-certified quality management system, to ensure consistent product quality. For your information, the results of all experiments are accessible by addressing Cat and Lot number on web at rojetechnoloes.com


The MiRJia Kit is designed for isolating all form of RNA molecules from 0.5-100 mg tissue samples or up to 1×107 cells. Fresh or frozen tissue samples should be lysed and homogenized. Aqueous phase is separated using chloroform. Then, RNA binding to the silica membrane is achieved selectively, by the addition of Ethanol to the lysate. Contaminants are removed by two specific kind of washing buffers. Pure miRNA and total RNA is finally eluted in nuclease free water. Isolated RNA (miRNA or total RNA) is ready to use in downstream applications. It has A 260/ A 280 ratios of 1.9–2.3 by spectrophotometer, confirming high purity.

Equipment & Reagents to Be Supplied by User

  • Absolute Ethanol
  • 1.5 ml RNase free microcentrifuge tubes
  • Pipets and RNase free pipet tips
  • Benchtop refrigerated microcentrifuge
  • Vortex
  • TissueLyser/ Mortar and pestle/ Homogenizer
  • Syringe and needles


The isolated RNA can be used in many downstream applications:

  • RNA Sequencing
  • cDNA synthesis
  • Poly A+ RNA selection
  • Microarrays
  • RT-PCR and real-time RT-PC
  • Northern, dot blot analysis
