AssayRef Reference Controls

     Assaypro provides reference controls for several applications, such as assay standards, spiking and recovery studies, western blot. Our reference controls are prepared from purified or recombinant proteins.


     Protein purity is verified via SDS-PAGE and HPLC. Protein concentration is determined by protein assay, A280 measurement, and ELISA. The final concentration is established after evaluation by the previously mentioned methods. The reference control will then be validated against sets of commercially available controls (e.g. WHO references).



  • Assay standard
  • Control for spiking and recovery studies
  • Western blot positive control
