New Human Zonulin ELISA Kit Is Launched by Creative Diagnostics for Researchers

Creative Diagnostics launches Human Zonulin ELISA Kit for the quantitative determination of Zonulin in serum, EDTA-plasma or stool.

Creative Diagnostics, a global leader in the development of life science research reagents, is continuing to expand its offering of ELISA products with the launch of the Human Zonulin ELISA Kit (Cat.No: DEIA6690). This newly released enzyme immuno assay can be used for the quantitative determination of Zonulin in serum, EDTA-plasma or stool.   

Zonulin is a novel human protein analogue to the Vibrio cholerae derived Zonula ccludens toxin, which participates in tight junctions between cells of the wall of the digestive tract. Zonulin binds to a specific receptor on the surface of intestinal epithelia and triggers a cascade of biochemical events which induces tight junction disassembly and a subsequent permeability increase of the intestinal epithelia, allowing some substances to pass through and activate immune reactions.

“This assay is based on the method of competitive enzyme linked immunoassays. As a first preparation step, a biotinylated zonulin tracer is added to the samples, standards and controls. Afterwards, aliquots of the treated preparations are transferred and incubated in microtiter plate wells coated with polyclonal anti zonulin antibodies…” explained Dr. Jessica Waldorf, chief scientific officer of R&D department of Creative Diagnostics.

“With a strong dedication to quality and customer service since its foundation, Creative Diagnostics always supports its clients especially in the fields of bioassays, microbiology, in vitro toxicology, pharmacology, and biocompatibility, etc. For those pharmaceutical and biotech companies worldwide, Creative Diagnostics is always your trusted and experienced immunoassay expert and partner,” said Dr. Randy S. Vaughn, senior researcher at Creative Diagnostics.
