This EIA kit is used for quantitative determination of human PYY [both PYY(3-36) and PYY(1-36)] in serum and plasma samples. The kit is characterized by its sensitive quantification and high specificity. In addition, it is not influenced by other components in samples. Human PYY (3-36) standard is a highly purified synthetic product. Research Use Only. Not for Use in Diagnostic Procedures.
This enzyme immunoassay (EIA) kit is a stable and convenient assay for human peptide YY
(PYY). PYY was isolated initially by Tatemoto et al. (1980) from pig duodenum and shown to
be a polypeptide consisting of 36 amino acid residues. PYY is homologous to pancreatic
polypeptide (PP) and neuropeptide Y (NPY). PYY is localized mainly in endocrine cells in the
intestine (ileum, colon, and rectum). PYY shows inhibitory action on contraction of the
gastrointestinal tract and on secretion of pancreatic and gastric juice. PYY is released by
consuming food. Levels in human blood decrease after intestinal resection, possibly due to a
decrease in the number of endocrine cells secreting PYY. This EIA kit uses synthetic human
PYY (3-36) as the assay standard and biotinylated human PYY (3-36) as the labeled antigen.
1. What percentage of your IgE allergy testing panel consists of molecular allergens rather than allergen extracts? The ALEX2 IgE allergen panel consists of 117 extracts and 183 molecular allergens. This represents the largest panel of molecular allergens on the market, including 50 unique...
Cases of food and environmental allergies have been increasing over the last decade. While conservative estimates suggest IgE-mediated allergy affects 6-8% of children and 2-3% of adults, some estimates are as high as 30%.3, 2 Symptoms can range from mild to severe and include itching, hives,...
Food sensitivity or food intolerance involves a non-allergic response to a food or food additive. In a recent on-line survey conducted in the U.S., 24% of adults aged 18 to 79 reported a food intolerance. While a food allergy is typically mediated by IgE antibodies, adverse reactions to food...
In a head-to-head comparison of FDA-cleared assays and a novel ALPCO method, investigators observed wide variability in specificity and false-positive rates across platforms, raising important questions about standardization and clinical interpretation.
July 22, 2025 – Salem, NH – NuvinkaDx, a leading innovator in diagnostic solutions, today announced two significant product and regulatory milestones from its operating companies, GeneProof and ALPCO.
