Angiopoietin-Like Protein 4 (ANGPTL4) ELISA

Angiopoietin-Like Protein 4 (ANGPTL4) ELISAThe Angiopoietin like Protein 4 (ANGPTL 4) ELISA is an enzyme immunoassay for the quantitative determination of Angiopoietin like Protein 4 (ANGPTL 4) in human serum and plasma. The microtiter plate is coated with the antibody specifically binding the Angiopoietin like Protein 4. The human serum or plasma (citrate, EDTA) is incubated in the plate with the capture antibody. The specimen is washed out and the specifically bound protein is incubated with

The Angiopoietin like Protein 4 (ANGPTL-4) ELISA is an enzyme immunoassay for the quantitative determination of Angiopoietin like Protein 4 (ANGPTL-4) in human serum and plasma.

The microtiter plate is coated with the antibody specifically binding the Angiopoietin-like Protein 4. The human serum or plasma (citrate, EDTA) is incubated in the plate with the capture antibody. The specimen is washed out and the specifically bound protein is incubated with biotin-labelled detection antibody. Following another washing step, Streptavidin-HRP conjugate is added into the well. Unbound reagent is then washed out. Horseradish peroxidase (HRP) bound in the complex reacts with the chromogenic substrate (TMB) creating the blue color. The reaction is stopped by addition of STOP solution (H2SO4). The absorbance values are measured at 450 nm (optionally 450/630 nm) and are proportional to the concentration of ANGPTL-4 in the specimen. The concentration of ANGPTL-4 in unknown samples is determined from the calibration curve which is created by plotting the absorbance values against the standard concentration values.
