The FT4 (Free Thyroxine) ELISA Kit measures fT4 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 fT4. fT4 in the sample or standard competes with a fixed amount of biotin-labeled fT4 for sites on a pre-coated antibody specific to fT4. 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 fT4 in the sample. The concentration of the target substance is inversely proportional to the OD450 value.

Eye opening and powerful
Format: Kindle
TD Jakes gives great insight into who we are and how to find purpose in this book. His illustrations and insights into the lives of Elisha and Elijah are really good. His focus on doing well where we are and being faithful in our current season were just what I needed to hear. If you need motivating for the next season of your life or if you are struggling to get to the next season of your life, this book will help you I'm sure.
