Elisa colorimetric insulin assay kit

Manufactured by Crystal Chem

The ELISA colorimetric insulin assay kit is a laboratory equipment used to quantify insulin levels in biological samples. It employs the enzyme-linked immunosorbent assay (ELISA) technique, which utilizes specific antibodies and color-changing enzymes to detect and measure the concentration of insulin.

Plasma Biomarker Quantification Protocol

Plasma insulin levels were determined using ELISA colorimetric insulin assay kit (Crystal Chem). For iron measurement, plasma samples were collected from heparinized blood and used for measurement of total circulating iron (Fe2+ and Fe3+) using the QuantiChrom Iron Assay Kit (BioAssay Systems). Plasma hepcidin levels were determined using Hepcidin-Murine CompeteTM ELISA (Intrinsic Life Sciences). For GLP-1, whole blood samples were collected in microtubes treated with 1:10μl anti-proteolytic cocktail (EDTA/Aprotinin/Heparin) to prevent enzymatic GLP-1 degradation. Plasma total GLP-1 levels were determined using the Meso Scale Discovery Platform according to the manufacturer’s instructions (Meso Scale Discovery). All assays were performed according to the manufacturer’s instructions.

Glucose Tolerance and Gastric Emptying

During glucose tolerance tests, all mice were fasted for 4–5 hr prior to oral administration of dextrose (2 g/kg body weight). Tail vein blood glucose levels were measured using Accu-Chek glucometers (Accu-Chek Aviva Plus, Roche Diagnostics) or Biosen C-line glucose analyzer (EKF diagnostic) at 0, 15, 30, 45, 60, 90, and 120 min post glucose administration. Gastric emptying rate was assessed by an oral gavage of glucose (2 g/kg) with acetaminophen (100 mg/kg) in 4–5 hr fasted mice. Blood was collected from the tail vein at baseline and 10  min after gavage in EDTA-coated microtubes. Plasma acetaminophen levels were used to assess the rate of gastric emptying and were measured using spectrophotometry assay (Sekisui Diagnostics). Plasma insulin levels were determined using ELISA colorimetric insulin assay kit (Crystal Chem).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
