Okadaic acid is a potent neurotoxin and phosphatase inhibitor from dinoflagellate black sponges that are associated with seafood poisonings.
Okadaic Acid (OA) is a one of the diarrhetic shellfish poisons (DSP) produced by dinoflagellate genera Dinophysis and Prorocentrum. There are several chemically different toxins associated with DSP.
They are lipophilic and polyether compounds and can be divided into three main groups:
Acidic toxins
Neutral toxins
Other toxins 2 Contamination of shellfish with OA has been associated with harmful algae blooms throughout the world.
In humans, DSP causes dose-dependent symptoms of diarrhea, nausea, and vomiting. The action levels established by the FDA for OA is 200ppb. The EU has established a level of 160 ppb of OA or its equivalent.
The Attogene Okadaic acid ELISA kit enables international and government regulatory agencies, food manufacturers and processors, as well as quality assurance organizations to detect OA in food, feed, fish, and environmental samples of concern.
Okadaic acid is the causative agent of Diarrhetic Shellfish Poisoning (DSP).

Our 384-well PCR plates have a rigid fully-skirted frame which remains stable during thermal cycling.
About
Our 384-well plate has a rigid, fully-skirted frame which remains stable during thermal cycling. The rigidity of the plate lends itself to automated and high-throughput PCR environments where robotic handling maybe in use.
The 2-component design reduces the risk of evaporation due to a poor sealing, commonly seen with 1-component PCR plates. 100% virgin medical grade polypropylene is used for the 384 wells, with a maximum capacity of 45 µL Certified free from DNase, RNase, nucleases and human gDNA.
EXTRAClean Cell Culture Media Exosome Purification and RNA Isolation Kits

Product Info
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.
All sizes, including miRNA and small RNA (< 200 nt)
Elution Volume
50-100 μL
Time to Complete 10 Purifications
40-45 minutes
