Order No.: SC0064


Dexamethasone, also known as flumethasone, flumazetone, desamethasone, is a glucocorticoid. Its derivatives include hydrocortisone and prednisone. Dexamethasone has anti-inflammatory, anti-allergic, anti-rheumatic, and immunosuppressive effects. However, this hormone remains in the food and has potential harm to humans. Long-term consumption of food left over from veterinary drugs will cause veterinary drugs to accumulate in the body. When its concentration reaches a certain amount, it will cause various acute or chronic poisoning to the human body.

Dexamethasone is a hormonal drug that can disrupt hormone secretion in the body, reduce the body’s immunity, cause muscle atrophy and weakness, osteoporosis and growth retardation, and other direct harms. It can also cause fever, weakness, mental depression, loss of appetite, symptoms such as decreased blood sugar and blood pressure. Countries such as the European Union have banned dexamethasone as a growth promoter for livestock and used it in animal husbandry.

Use Principles

Dexamethasone ELISA Test Kit is an indirect competitive enzyme-linked immunoassay. The dexamethasone antigen is precoated on the wells. The precoated antigen compete the dexamethasone antibody (antibody solution) with dexamethasone in the sample, anti- dexamethasone antibody binds to the dexamethasone-HRP enzyme conjugate. Then pipette the substrate solution into the wells to convert the color into a blue product.

The color of unknown samples is compared to the color of the standards and the dexamethasone concentration of the samples is derived. The absorbance is inversely proportional to the dexamethasone concentration in the sample.

Immunoaffinity Column for 2-in-1 Aflatoxins (B1,B2,G1,G2) and Ochratoxin A

The immunoaffinity column can selectively adsorb aflatoxin (B1, B2, G1, G2) and Ochratoxin A from the sample solution, thereby having a highly targeted purification effect on the sample. The sample  solution that has been purified by passing through the affinity column can be directly used for HPLC analysis or for LC-MS/MS analysis after concentrating with nitrogen gas and resuspended.Order No.: HCM3725B/HCM3750BProduct Properties: AFT B1/B2/G1/G2 300ng, OTA 100ngSpecifications: 3mL,25T/50T

Immunoaffinity Column for Aflatoxin B1,B2,G1,G2

The immunoaffinity column can selectively adsorb aflatoxins (B1, B2, G1, G2) from the sample solution, thereby purifying the sample. The purified sample solution can then be directly used for HPLC or LC-MS/MS analysis.Affinity columns can be used in combination with HPLC or LC-MS/MS to achieve rapid testing, and to increase signal-noise ratio  and improve the accuracy of the detection method.
