ANG II (Angiotensin II) ELISA Kit

ANG II (Angiotensin II) ELISA KitThe ANG II (Angiotensin II) ELISA Kit measures ANG II in Universal Serum, Plasma, Cell Culture Supernatant, Cell or Tissue Lysate. This kit is based on Competitive ELISA detection method and takes 2h assay time. The microplate provided in this kit has been precoated with ANG II. ANG II in the sample or standard competes with a fixed amount of biotin labeled ANG II for sites on a pre coated antibody specific to ANG II. Free components are washed off.

The ANG II (Angiotensin II) ELISA Kit measures ANG II in Universal Serum, Plasma, Cell Culture Supernatant, Cell or Tissue Lysate. This kit is based on Competitive-ELISA detection method and takes 2h assay time. The microplate provided in this kit has been precoated with ANG II. ANG II in the sample or standard competes with a fixed amount of biotin-labeled ANG II for sites on a pre-coated antibody specific to ANG II. Free components are washed off. After adding HRP-Streptavidin Conjugate (SABC), biotin specifically binds with streptavidin to form immune complexes. Wash off unbound conjugate. Add TMB substrate solution. Then, TMB was catalyzed by HRP to produce a blue color product that turned yellow after adding a stop solution. Read the O.D. absorbance at 450nm in a microplate reader. Compare OD450 value of sample with the standard curve through curve fitting software to determine the concentration of ANG II in the sample. The concentration of the target substance is inversely proportional to the OD450 value.
