Description

FA/VB9 (Folic Acid/Vitamin B9) ELISA KitThe FA VB9 (Folic Acid Vitamin B9) ELISA Kit measures FA VB9 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 FA VB9. FA VB9 in the sample or standard competes with a fixed amount of biotin labeled FA VB9 for sites on a pre coated antibody specific to FA VB9. Free components are washed

The FA/VB9 (Folic Acid/Vitamin B9) ELISA Kit measures FA/VB9 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 FA/VB9. FA/VB9 in the sample or standard competes with a fixed amount of biotin-labeled FA/VB9 for sites on a pre-coated antibody specific to FA/VB9. 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 FA/VB9 in the sample. The concentration of the target substance is inversely proportional to the OD450 value.

Great shoes and good fit. Fits as expected. The sole has worn down a bit quicker than I had hoped but my kiddo wears them everyday. I would buy them again for sure!
