Description

Not all cyanobacterial strains produce toxins. However, the toxin-producing strains cannot be distinguished from the nontoxin-producing strains by traditional light microscopy, commonly
used to monitor water bodies.  An alternative for the differentiation of potentially toxic strains from nontoxic strains is to use molecular methods to detect the presence of toxin biosynthetic genes. Such methods are already available and could be used for the detection and identification of potential microcystin and nodularin producers present in environmental samples (Attogene catalog number NA2024).

Screening for the toxin itself, can be very costly.  In turn, real time PCR for the detection of the anaC gene in cyanobacterial strains and environmental samples can be a key indicator for the prescense of cyanobacteria capable of expressing the Anatoxin toxin.  Attogen has thus, designed primer pairs and probes targeting a the conserved anaC gene region in order to enable the amplification and detection of several producer genera using real time PCR.  Screening for the toxin genes can save significant costs and act as a triage for samples needing to be analyzed for the toxin itself.

Overview

• Isolate all sizes of circulating and exosomal RNA, including microRNA
• Isolate all sizes of circulating DNA from plasma and serum samples
• Isolate viral and bacterial DNA and RNA
• Versatile plasma and serum input volumes (10 µL – 200 µL)
• No phenol extractions
• Bind and elute all RNA irrespective of size or GC content, without bias
• Concentrate circulating RNA, exosomal RNA and cell-free circulating DNA into a flexible elution volume ranging from 10 µL to 25 µL
• Isolate inhibitor-free nucleic acids
• Purify high-quality RNA and DNA in 30 minutes
• Purified RNA is suitable for a variety of downstream applications, including Small RNA Sequencing. Find out more information on Norgen’s NGS services
• Purification is based on spin column chromatography that uses Norgen’s proprietary resin separation matrix

Norgen’s Plasma/Serum RNA/DNA Purification Mini Kit provides a fast, reliable, reproducible and simple procedure for the sequential isolation of circulating RNA, exosomal RNA and Cell-Free Circulating DNA (cfc) from the same Plasma/Serum sample. It can sequentially isolated RNA and DNA from small plasma/serum input ranging from 10 µL to 200 µL. The kit is designed to isolate all sizes of circulating RNA, including microRNA, all sizes of exosomal RNA as well as all sizes of cfc-DNA from fresh or frozen plasma or serum samples. Norgen’s Plasma/Serum RNA Purification Kit provides a clear advantage over other available kits in that it does not require Phenol/Chloroform or any Protease treatments for the isolation of plasma/serum RNA or DNA . RNA and DNA can be eluted into a flexible elution volume ranging from 10 µL to 25 µL. Purified RNA can be used in a number of sensitive downstream applications including reverse transcription qPCR, reverse transcription PCR, NGS, Northern blotting, RNase protection and primer extension, and expression array assays. Purified DNA can be used in a number of sensitive downstream applications including PCR, qPCR, methylation-sensitive PCR and Southern Blot analysis.

Background

Typical yields of free-circulating, exosomal RNA and cfc-DNA vary depending on the input sample, as the amount of RNA and/or DNA present in plasma and serum will depend upon the health status of the individual.  Normally, the RNA/DNA yield from plasma or serum is highly variable (range from 1 to 100 ng/mL). Variability is also observed between samples collected from the same donor at different times during the day. This kit is suitable for the isolation of RNA/DNA from serum or plasma prepared from blood collected on either EDTA or Citrate. Plasma samples prepared from blood collected on heparin should not be used as heparin can significantly interfere with many downstream applications such as RT-PCR.
