In Western Blotting experiments, Blocking Buffer is used before attaching antibodies. This step is essentially to eliminate non-specific reactions to Membrane in advance. In the case of animal-derived proteins such as Skim Milk, BSA, etc., which are usually used, there are problems such as being denatured or having a high non-specific response to specific antibodies. Smart-Block™ does not use animal proteins, so it does not have cross activity and does not cause problems in the detection of Biotin System, Phosphor Protein. The blocking time, which usually takes about an hour, has been reduced to 5 minutes, and it has excellent storage properties, so it can be stored for a long time even at room temperature.
