WebGood Western blot blocking methods are crucial in order to achieve clean and reliable results. Protein samples are first ran on a polyacrylamide gel to separate proteins by size. The proteins are then transferred to a nitrocellulose or PVDF membrane. WebWestern blot aims to identify specific proteins within a complex mixture. The western blot technique requires samples to be resolved based on size through sodium dodecyl sulfate-polyacrylamide gel electrophoresis ( SDS PAGE ), following which they are transferred to and immobilized on a membrane before antibody-based detection.
