Enterokinase Elisa Kit By Hangzhou Junfeng Bioengineering Co. Ltd

The kit uses anti Enterokinase antibody as the coating antibody, the enzyme labeled anti enterokinase antibody as the detection antibody, the highly sensitive TMB as the substrate, and the Enterokinase as the standard to quantitatively detect Enterokinase in the sample. This kit is characterized by good specificity, high sensitivity and stability,
The lowest detectable level of Enterokinase is 0.1ng/ml.
Principle
This kit uses double antibody sandwich method to detect Enterokinase residuals. The Enterokinase antibody is coated on the microplate, and the Enterokinase in the sample or standard is combined with the antibody fixed on the microplate. After the unconjugated sample or standard is washed with washing solution, the HRP-labeled Enterokinase antibody is added for incubation, and the enzyme labeled antibody is combined with Enterokinase. Wash the unconjugated enzyme labeled antibody, add TMB substrate solution to the microplate, incubate it in dark to form a blue complex, stop the reaction with stop solution, and the color changes from blue to yellow. Determine the absorbance value of the complex, and fit the standard curve with the OD value of the standard. The Enterokinase concentration of the sample can be calculated from the OD value of the sample through the formula fitted with the standard curve.
