Description

The Saxitoxin (PSP) ELISA Kit is a competitive ELISA for the quantitative analysis of saxitoxin in shellfish samples. This kit can be used for rapid test of Saxition in samples such as mussels and lobster tomalley.

The Saxitoxin (PSP) ELISA Kit uses a polyclonal antibody that binds both saxitoxin and a Saxitoxin-enzyme conjugate. Saxitoxin in the sample competes with the Saxitoxin-enzyme conjugate for a limited number of antibody binding sites.

DNA Concentrator (Magnetic Beads)

The DNA Concentrator (Magnetic Beads) can be used to efficiently concentrate DNA/RNA from various samples with low concentration without the need of a DNA vacuum concentrator. Solid Phase Reversible Immobilization (SPRI) magnetic beads are well used for DNA and RNA purification and concentration. The beads are paramagnetic particles coated with carboxyl groups that reversibly bind to DNA and RNA.

The concentrator protocol is simple: mix Concentrator Buffer and Concentrator Beads with the sample, wash, and elute pure DNA in a small volume to concentrate the DNA samples. Moreover, the DNA/RNA samples are also purified during the procedure. The beads with our unique technology purify DNA/RNA samples effectively by removing unwanted components such as dNTPs, enzymes, detergents, proteins, and other contaminants.

However, traditional magnetic beads can only bind nucleic acids that are 100 bp or longer. Nucleic acids shorter than 100 bp are not effectively recovered. We have successfully developed the kit that overcomes the hurdle of short nucleic acids recovery. The reagent can be used for concentration of samples from genomic DNA to short DNA/RNA.

Recovery rate

• >90% for DNA size >30 bp
• >80% for DNA size between 20-29 bp

Features

• Effective concentrator of DNA and RNA samples, even small DNA, RNA, oligos
• Binding capacity: 10 ug DNA per prep
• Removal of unwanted components and other impurities

Overview

• Ensure optimal results for sensitive applications like NGS
• Up to a tenfold increase in microRNA mapping during sequencing runs to reduce costs
• Purification and enrichment of intact cell culture media exosomes for functional studies
• No phenol extractions, Proteinase K treatment, nor carrier RNA required
• No time-consuming ultracentrifugation, filtration nor special syringes required
• No precipitation reagents nor overnight incubation required
• Pure exosomes are purified and are free-from any other RNA-binding proteins
• Purification is based on EXTRAClean spin column chromatography that uses Norgen’s proprietary resin separation matrix

Norgen’s EXTRAClean Cell Culture Media Exosome Purification and RNA Isolation Kits constitute all-in-one systems for the purification of exosomes and the subsequent isolation of RNA from different cell culture media sample volumes. The purification is based on spin column chromatography that employs Norgen’s proprietary resin. The EXTRAClean columns undergo stringent processing and rigorous quality control measures to minimize contamination traces, ensuring optimal results for sensitive applications such as NGS. The kit is designed to isolate all sizes of RNA, including microRNA. The kit provides a clear advantage over other available kits in that it does not require any special instrumentation, protein precipitation reagents, extension tubes, phenol/chloroform or protease treatments. Moreover, the kits allows the user to elute into flexible elution volumes ranging from 50 μL to 100 μL. The purified RNA is free from any protein-bound circulating RNA and is of the highest integrity. The purified RNA can be used in a number of downstream applications including real time PCR, Sequencing based applications, reverse transcription PCR, Northern blotting, RNase protection and primer extension, and expression array assays.
