These blocking buffers contains casein protein that is purified from milk by the Hammarsten method. The phosphate- and Tris-buffered saline formulations are used for blocking excess binding sites on membranes and microplates in antibody-based detection methods. Blocker Casein Buffers are 1% (w/v) casein, which corresponds to the optimal concentration for most applications.


  • Purified casein – single-protein blocking buffer provides fewer chances of cross-reaction with assay components than serum or milk solutions

  • Easy to use – 1% casein solutions are ready to use; can be diluted further as needed

  • Flexible – available in PBS and TBS formulations to suit a variety of applications

  • Safe – stable, thimerosal-free formulations
