Dexamethasone ELISA test Kit

Dexamethasone ELISA test Kit Catalog No. LSY-10042 1. Principle This test kit is based on the competitive enzyme immunoassay for the detection of Dexamethasone in the sample. The coupling antigen is pre-coated on the micro-well stripes. The Dexamethasone in the sample and the coupling antigen pre-coated on the micro-well stripes compete for the anti-Dexamethasone antibody. After the addition of the enzyme conjugate, the TMB substrate is added for coloration. The optical density (OD) value of the sample has a negative correlation with the Dexamethasone in it. This value is compared to the standard curve and the Dexamethasone concentration is subsequently obtained. 2.
