Quality Biological Inc Blocking Solution, 500ML
Supplier: Quality Biological Inc 351080101
Blocking is a very important step of western blotting as it prevents antibodies from binding to the membrane nonspecifically. Blocking is often made with 5% BSA or nonfat dried milk to reduce the background. Nonfat dried milk is often preferred as it is inexpensive and widely available. However milk proteins are not compatible with all detection labels so care must be taken to choose the appropriate blocking solution.
