Abstract:The concept of specific binding of an antibody to an antigen can be understood easily through immuno-blotting experiments. For dot blotting the protein samples on a membrane, dot-blotters or filtration manifolds are necessary. However, such pieces of apparatus are complex, fragile and expensive. We report the simple and inexpensive construction and use of a dot-blotter using a magnetic rubber sheet.
