Intended Use of RNJia Phenol Free PB Kit 

The RNJia phenol-free PB Kit provides the procedures necessary for purifying RNA from peripheral blood mononuclear cell, WBC and whole blood. Notice that, RNJia phenol-free PB 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 ROJE Technologies

Quality Control

RNJia phenol-free PB 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 ROJE Technologies


The RNJia phenol-free PB Kit is designed for isolating all forms of RNA molecules from up to 1×107 WBCs. Fresh or frozen samples should be lysed and homogenized. 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 RNA is finally eluted in nuclease-free water. Isolated RNA is ready to use in downstream applications. It has A260/A280 ratios of 1.8–2.3 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 microcentrifuge
  • Vortex
  • Homogenizer/ Syringe and needles


Applications of RNJia Phenol Free PB Kit

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-PCR
  • Northern, dot blot analysis

Recommended starting material:

To reach optimized results it is better to follow as listed below. The size of the recommended material to use with determined RLB amount are written in Table 2.

Table 2. Appropriate sample size and amount of RLB.

Whole blood (ml) WBCs Number RLB Amount (µl)
Up to 0.5 Up to 2 x 106 350
0.5 to 1.5 2 x 106 to 1 x 107 600
