Description

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:

1. Acidic toxins
2. Neutral toxins
3. 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).

NH-bis(PEG4-Propargyl) is a bifunctional PEG compound containing two terminal alkynes that are joined together at a secondary amine. Terminal alkynes are reactive towards azides in copper (I) click chemistry to form stable triazoles with the target compound. The secondary amine joining the two arms can be used as a nucleophile such as in alkylation via reductive amination or in forming amides with carboxylic acids or activated NHS esters. The use of a central amine also allows for hydrogen bonding, further increasing this compound’s water solubility.
