Overview

• Excellent separation and purification of cytoplasmic and nuclear RNA
• Convenient and fast spin column format
• High quality and yield of RNA
• Isolate full diversity of RNA (including microRNA) without phenol
• Purified RNA is ready for any application including RT-PCR, qRT-PCR, RNA-Seq, arrays and more
• Cytoplasmic RNA is free of DNA and ready for direct use in RT-PCR/qRT-PCR
• Purification is based on spin column chromatography that uses Norgen’s proprietary resin separation matrix

This kit provides a rapid method for the isolation and purification of both cytoplasmic and nuclear RNA from cultured animal cells and small tissue samples. The kit can be used to isolate all sizes of RNA from the cytoplasmic and nuclear RNA fractions, including all small RNA species without any requirement for phenol.   Included in the kit are sufficient reagents to perform either 50 cytoplasmic RNA preparations or 25 cytoplasmic and 25 nuclear RNA preparations.   Ten samples can be processed in approximately 45 minutes.  This kit is also available in a 100 prep size.    

Background

In certain circumstances it is desirable to be able to isolate fractionated RNA as opposed to total RNA. For example, it may be preferable to isolate only mature, cytoplasmic RNA for some studies on expression profiling. Alternatively it may be desirable to isolate nuclear RNA in order to investigate and study pre-processed (non-spliced) RNA. Furthermore, this kit can be used to isolate RNA for downstream applications where it is necessary to avoid DNA contamination, since the cytoplasmic fraction has been shown to be free of all traces of genomic DNA.

Description

Nucleic acid testing (NAT) is the method of choice for detection and quantification of a wide range of micro organisms. Primerdesign manufactures and supplies high quality quantitative real-time PCR kits for the detection and simultaneous quantification of numerous significant pathogens . A copy number standard curve is provided for quantification and an the internal extraction template (DNA or RNA), controls for the quality of the nucleic acid extraction and eliminates false negative results.

The kit is designed with the broadest possible detection profile to ensure that all clinically relevant strains and subtypes are detected. Target sequences are selected by working with data from key opinion leaders in the field. Multiple sequence alignments and unprecedented real-time PCR expertise in design and validation ensure the best possible kit.

Details of the target and priming specificity are included in the individual handbooks above.

Plasmid Purification Magnetic Beads (RNA Depletion)

Plasmid isolation from bacterial cultures is one of the most popular techniques in biomedical research and pharmaceutical industries. However, it is common that the isolated plasmid DNA is usually contaminated with varied degrees of host RNA. Plasmid purification is necessary to reduce the impact on downstream applications by removing RNA contamination.

We have developed a simple reagent to completely remove RNA contamination in the isolated plasmid samples using Solid Phase Reversible Immobilization (SPRI) beads. SPRI beads consist of paramagnetic particles coated with carboxyl groups that reversibly bind DNA. Our Plasmid Purification Magnetic Beads (RNA Depletion) combines BioDynami’s proprietary chemistries with the reversible DNA-binding properties of SPRI magnetic beads. The reagent removes RNA and recovers the plasmid in the same step.  Moreover, unwanted components such as salts, dNTPs, proteins, enzymes, and other impurities can also be removed simultaneously.

Plasmid can be used for downstream applications such as enzymatic digestion, transformation, transfection and molecular cloning etc.  The beads can be an effective and inexpensive reagent for bacterial RNA depletion for routine plasmid purification.

Features

• Effective depletion of bacterial RNA by RNase
• High recovery rate of plasmid DNA by magnetic beads
• Removal of unwanted components and impurities
• Simple and fast beads-based protocol

Designed for those labs wishing to separate magnetic beads into rings.

The Permagen ring magnet low elution plate with integrated cushion base plate was designed for use in automation applications where volumes as low as 5 µL are required. Most PCR plates are bent, leading to inconsistent lab results. Unlike most products, we have added an angled frame around the top of our plate, this helps with two things, straightening out the PCR plate, and leading it to the proper location on the magnets during automation while the cushion assist compensates for labware inconsistencies.

Description

Ractopamine ELISA Kit

Ractopamine ELISA Test Kit is a competitive enzyme immunoassay for detection in meat, feed, liver, kidney, milk, urine, serum and plasma. Ractopamine has been banned for use as a livestock growth promoter in many countries around the world. To prevent ractopamine residues from entering the food chain, both producers and government surveillance agencies need technologies and methods that can provide rapid, accurate and reliable detection at specific sensitivities. This kit enables government agencies, food manufacturers, as well as quality assurance organizations, to detect ractopamine as low as 0.1 ng/g or ppb level in a variety of sample types.
