Following protein transfer, it is important to block the unreacted sites on the membrane using inert proteins and/or nonionic detergent to reduce levels of nonspecific protein binding during the assay. Blocking buffers should block all unreacted sites without disrupting target protein-membrane interactions or affect epitope availability.
There are three factors to consider when choosing an appropriate blocking agent for your specific protocol:
(Click the meme for blocking optimization tips!)
The most typical blocking solutions are nonfat dry milk, casein, gelatin, or Tween-20 in TBS and/or PBS buffers. Here are some advantages and disadvantages of some common blocking agents:
We advise reviewing the data sheet for any recommended blocking agents because antibodies can be very sensitive to the blocking agents used.
Here is a summary workflow for a typical WB experimental protocol along with necessary reagents for each step.
