Western blotting is a multi-step process that can take hours or one to two days to complete, depending on the methods used. Below are videos that detail the common steps used to perform a western blot, from separating proteins in protein gel electrophoresis to developing the blot.
Separate proteins based on molecular weight.
Transfer the protein from gel to a solid-support membrane.
Block unreacted sites on the membrane to reduce the amount of nonspecific binding. Probe blot with primary and secondary antibodies.
Detect proteins based on the detection method that you choose.
Capture and analyze your image.
Learn about the signal accumulation, multi-exposure, and region-of-interest Smart Exposure features of the Invitrogen iBright Imaging System.
This video demonstrates how to use Invitrogen No-Stain Protein Labeling Reagent and the iBright Imaging System to capture and quantitate western blotting data using total protein normalization.
Stripping and reprobe the blot for another protein of interest.
