Although no blocking buffer is ideal for every experimental situation, you are likely to obtain excellent results from the start with StartingBlock Blocking Buffers. This is because the blocking agent is performs well with an extremely wide range of antibodies and assay systems. Our scientists have yet to encounter an antibody combination or other protein probing system in which StartingBlock Blocking Buffer is not compatible.


  • Compatible with many detection systems – Western blot, ELISA and IHC with antibody or avidin/biotin probes (blocker is serum and biotin-free)

  • Short blocking times – less than 15 minutes for nitrocellulose or PVDF membranes, almost instantaneous for polystyrene microplate wells

  • Strip and reprobe without reblocking – blots stay blocked even after stripping with Thermo Scientific Restore Stripping Buffer (Part No. 21059)

  • High signal:noise ratio – biotin- and serum protein-free formulation contributes to acheiving signal-to-noise ratios from 10:1 to 20:1

  • Convenient formats – available ready-to-use 1X formulations in PBS and TBS, with and without Tween™-20 detergent
