Benefits

  • ACCURATE AND RELIABLE ENZYMATIC ASSAY

Assay principle: sandwich

21OH molecules are coated onto the ELISA plate wells. 21OH-biotin complexes constitute the liquid phase. 21OH-Ab bound to the 21OH immobilized onto the well will interact with 21OH-biotin to form a bridge. Addition of streptavidin peroxidase (SA-POD) detects the bound 21OH-biotin. The unbound SA-POD in excess is washed off before the addition of the peroxidase substrate TMB. Assay procedure: 16-20h at 2-8°C + 1 h RT / shaking + 20 min RT / shaking + 20 min RT in the dark.
