Reprobing of an existing membrane is a convenient means to immunoblot for multiple proteins independently when only a limited amount of sample is available. It should be noted that for the best possible results a fresh blot is always recommended. Reprobing can be a valuable method but with each reprobing of a blot there is potential for increased background signal. Additionally, it is recommended that you verify the removal of the first antibody complex prior to reprobing so that signal attributed to binding of the new antibody is not leftover signal from the first immunoblotting experiment. This can be done by re-exposing the blot to ECL reagents and making sure there is no signal prior to adding the next primary antibody.
NOTE: Prepare solutions with reverse osmosis deionized (RODI) or equivalently purified water.

Protocol Id: 19
Rabbit Anti-mouse IgG (Light Chain Specific) (D3V2A) mAb (HRP Conjugate) recognizes native mouse IgG. It also recognizes the denatured and reduced mouse IgG light chains (about 25 kDa) on a western blot.
Monoclonal antibody is produced by immunizing animals with native total mouse IgG.
Rabbit Anti-Mouse IgG (Light Chain Specific) (D3V2A) mAb (HRP Conjugate) only reacts with native IgG and denatured and reduced mouse IgG light chain. When performing immunopreciptiation (IP) followed by western blotting, the denatured mouse IgG heavy chains of the primary antibody used for IP run at approximately 50 kDa on the subsequent western blot and can often obscure bands of proteins that have similar molecular weights. Using Rabbit Anti-Mouse IgG (Light Chain Specific) (D3V2A) mAb (HRP Conjugate) as a secondary antibody will eliminate this problem.
