2-(Propargyl-PEG4-amido)-1,3bis(PEG1-methyl ester) is a crosslinker that can react with azide compounds or biomolecules via copper catalyzed Click Chemistry to form a stable triazole linkage. The methyl ester groups can be hydrolyzed, reduced, or substituted under different conditions.

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:
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).

The L-Glutamine/Ammonia (Rapid) test kit is a novel method for the specific, convenient, cost effective and rapid measurement and analysis of L-glutamine and ammonia in culture media/supernatants and other materials.
Note for Content: The number of manual tests per kit can be doubled if all volumes are halved. This can be readily accommodated using the MegaQuantTM Wave Spectrophotometer (D-MQWAVE).
