Description: Bilirubin, a byproduct of heme breakdown, can exist conjugated to glucuronic acid (direct) and as unconjugated (indirect). The unconjugated form is found in the blood bound to albumin and is transported to the liver. Bilirubin becomes conjugated to glucuronic acid in the liver, making it more soluble and allowing for excretion into bile. High levels of bilirubin have been correlated with jaundice and Gilbert?s syndrome while low levels have been associated with cardiovascular disease and diabetes mellitus.

Description: Our Pyruvate Assay Kit measures pyruvate in biological samples. First, pyruvate is oxidized by pyruvate oxidase, producing hydrogen peroxide. The hydrogen peroxide is then detected at ex. 530-570 nm/em. 590-600 nm using a specific fluorometric probe. Pyruvate levels in unknown samples are determined based on the provided pyruvate standard curve.

Description: Histamine is naturally occurring in food, with high concentrations associated with spoiled and fermented foods. Exposure to high levels of histamine through the ingestion of food can cause symptoms similar to an allergic response. Our Histamine Assay Kit detects total histamine from food samples using a colorimetric probe. Reduction of the probe yields color development proportional the histamine levels in the sample. Absorbance at 450nm is read after a one hour incubation at 37C and histamine levels are calculated based on a histamine standard curve.
