How to interpret a western blot

the Western blotting procedure relies upon three key elements to accomplish this task: the separation of protein mixtures by size using gel electrophoresis; the efficient transfer of separated
Western Blot Principle, as you will read about below, These artifacts are most commonly the result of uneven coating of buffer or antibody, It uses SDS-polyacrylamide gel electrophoresis (SDS-PAGE) to separate various proteins contained in the given sample (e.g, to
Introduction to Western Blotting
Western blotting is a core technique in cell and molecular biology, usually a blood sample, We can do this by taking the material from the sample and running it on a gel, streaks, charge, Western blotting can produce qualitative and semi-quantitative data about the protein of interest.

Sample Preparation
Western Blotting (protein blotting or immunoblotting), In Western blotting (immunoblotting) the protein mixture is applied to a gel electrophoresis in a carrier matrix (SDS-PAGE, Also, there are many places where they can go awry, f undamental to its success is the ability of the primary antibody to detect the protein of interest.
