Introduction

MagZol Reagent is a reagent system for the isolation of total RNA from cells and tissues. The reagent, a single-phase solution consisting of phenol and guanidine isothiocyanate, is modification of the single-step RNA isolation method developed by Chomczynski and Sacchi. The sample is homogenized and lysed in MagZol Reagent which maintains the integrity of the RNA, while disrupting and denaturing endogenous RNases and other cellular components. Extraction of the lysate with chloroform further denatures proteins and separates the mixture into an organic and an aqueous phase. RNA remains exclusively in the aqueous phase, and is subsequently recovered by isopropanol.

This method is suitable for small quantities of tissue (<100mg) and cells (<5 X10⁶), and large quantities of tissue (up to 1g) and cells (<10⁸), of human, animal, plant, or bacterial origin. The simplicity of the MagZol Reagent method allows simultaneous processing of a large number of samples. The entire procedure can be completed in one hour. Total RNA prepared in this manner can be used for Northern blot analysis, dot blot hybridization, poly(A) + selection, in vitro translation, RNase protection assay, and molecular cloning. For use in amplification by thermal cycling, treatment of the isolated RNA with RNase-free DNase I is recommended when the two amplimers lie within a single exon.

Advantages

• Flexible – sample amount can be adjusted according to the demand
• Cost performance -the most economical nucleic acid extraction technology

Storage and Stability

MagZol Reagent should be stored at 2-8°C upon arrival and is stable for at least 24 months under the condition. However, short-term storage (up to 12 weeks) at room temperature (15-25°C) does not affect its performance.

Introduction

HiPure Bacterial RNA Kit uses silica gel column purification to simplify the extraction. The whole process does not require phenol chloroform extraction and time-consuming alcohol precipitation. The kit is suitable for efficiently extracting RNA from various bacterial samples. The purified RNA can be directly used for RT-PCR, Northern hybridization, etc. The kit has included lysozyme and glass beads, which can be used to treat gram-negative bacteria which is easy to be lysed, as well as gram-positive bacteria which is hard to be lysed, including enterococcus faecalis, staphylococcus, etc.

Principle

Hipure silica gel column is based on glass fiber filter membrane with high binding force. Under the condition of high concentration of ionizing agent (such as guanidine hydrochloride or guanidine isothiocyanate), the filter membrane can adsorb nucleic acid through hydrogen bond and electrostatic, while protein and other impurities are not adsorbed and removed. The filter membrane adsorbed with nucleic acid is washed to remove the residual protein and salt. Finally, the nucleic acid adsorbed on the filter membrane can be washed out with low salt buffer (such as buffer TE) or water. The obtained nucleic acid has high purity and can be directly used in various downstream experiments.

Advantages

• Fast – several samples can be extracted in 30 minutes
• High purity – the purified RNA can be directly used in various downstream applications
• High recovery – RNA can be recovered at the level of PG
• Good repeatability – silica gel column purification technology can obtain ideal results every time
• Broad spectrum – it can deal with various bacteria, including Gram-positive bacteria that are difficult to be lysed
• Sufficient components – the kit contains carried lysozyme and glass beads

Storage and Stability

The kit components can be stored at room temperature (15–25°C) and are stable for at least 18 months under these conditions. Due to the lack of antibacterial agents, RNase Free Water may be contaminated by bacterial or fungal when placed or operated at room temperature. It is recommended to pack and store at 2-8°C to reduce contamination.

The kit is developed for RNA quantification. The RNA Quantification HS kit includes HS Dye, HS Dilution Buffer, and two RNA Standards. Simply dilute the HS Dye with the HS Dilution Buffer, add RNA sample, then read the concentration using the Qubit Fluorometer. The assay is accurate for RNA concentrations from 250 pg/µL to 100 ng/µL (Figure 1). The RNA Quantification High Sensitivity Kit has several advantages over traditional RNA quantitation such as stability, sensitivity, and contaminant tolerance.

Features

• • • Optimized condition for using with the Qubit Fluorometer
    • Uses the Qubit RNA High Sensitivity assay setting
    • Cuts costs by 60%

The performance of the BioDynami RNA Quantification HS kit is nearly identical to that of Thermo Fisher’s Qubit RNA HS kit (figure below).

Common contaminants such as detergents, solvents, salts, free nucleotides, or protein are well tolerated in the assay (Table 1).
