Western Blotting Principle Explained: How WB Works, WB protocols
WebUse a secondary antibody that was raised against the species in which the primary was raised (e.g primary is raised in rabbit, use anti-rabbit secondary). 2. Not enough primary antibody is bound to the protein of interest. Increase the concentration of primary or secondary antibodies. Incubate for longer periods of time (e.g. overnight) at 4°C. 3. WebIncreasing/decreasing primary antibody concentration can help amplify/reduce signal, respectively. Increasing/decreasing enzyme substrate incubation time can help amplify/reduce signal, respectively. Always run a positive control to ensure antibody activity (purified protein, transfected lysate, etc.). WebIncubation of primary antibody at its recommended dilution was performed at 4°C, 21°C, or 37°C for 1 hr, 2hr, or overnight (O/N). Conditions recommended by CST for primary … inch by inch school
