Dec 10, 2018 · In this video, we will cover the 3 major steps in generating a western blot: Separate, Transfer, and Detect. After protein samples have been prepared, the mixture is separated by molecular weight using protein gel electrophoresis, which is a standard laboratory technique by which charged protein molecules are transported through a matrix by an ...

1:5,000 (0.01–0.2 µg/mL) 1:5,000 (0.2–1.0 µg/mL) Incubate the membrane protein-side up in the primary antibody solution with agitation, for 1 hour at room temperature or overnight at 2–8°C. Ensure the volume of the antibody solution is enough to fully cover the membrane. Wash the membrane 3 times with agitation for 10 minutes each in ...
Mar 8, 2021 · Introduction to western blotting. In a western, proteins are: (1) separated by size, (2) transferred to a membrane, and. (3) detected using antibodies. Figure 1: Overview of the Western blot process. Starting with a mixture of proteins, it is separated in a gel, transferred to a membrane, stained with antibodies, and visualized.
