Sheep BETAEP (Beta-Endorphin) ELISA Kit
Sheep BETAEP (Beta-Endorphin) ELISA Kit
The Sheep BETAEP (Beta-Endorphin) ELISA Kit measures Beta-EP in Sheep 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 β-EP. β-EP in the sample or standard competes with a fixed amount of biotin-labeled β-EP for sites on a pre-coated antibody specific to β-EP. 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 β-EP in the sample. The concentration of the target substance is inversely proportional to the OD450 value.
