Expected Variability In Cell Assay Elisa

Description: Our CytoSelect 384-Well Cell Transformation Assay uses a modified soft agar 3D matrix to support the formation of colonies by neoplastic cells. Quantitation of cell transformation is performed on a fluorescence plate reader.

Description: Cell Biolabs? Cell Contraction Assays (Floating Matrix Model) provide a simple, in vitro system to assess cell contractivity and screen cell contraction mediators. The proprietary Cell Contraction Plate eliminates the matrix releasing step of the conventional contraction assay, providing a faster, higher-throughput method to assess cell contraction.

Description: Our StemTAG 96-Well Stem Cell Colony Formation Assay provides a high-throughput method to quantify ES cells in just 7-10 days, and no manual cell counting is required. Once colonies are formed, they may be analyzed in three different ways: 1. Lyse cells, then quantify in a fluorescence plate reader using dye included in the kit; 2. Lyse cells, then quantify alkaline phosphatase activity using reagents provided; or 3. Recover colonies from matrix for further culture or analysis.

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.

Description: The Lactose Assay Kit measures total lactose in milk based food products or biological samples such as blood or urine. Lactose is cleaved into glucose and galactose. Glucose is then oxidized, yielding hydrogen peroxide and D-gluconic acid. The hydrogen peroxide is detected by a fluorometric probe.

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.
