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: 10
Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA and 50% glycerol. Store at –20°C. Do not aliquot the antibody.
SCAP Antibody recognizes endogenous levels of total SCAP protein.
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Gly193 of human SCAP protein. Antibodies are purified by protein A and peptide affinity chromatography.
SREBP cleavage activating protein (SCAP) is a membrane-bound protein essential in regulating sterol regulatory element binding protein (SREBP) processing (1). In cholesterol-starved cells, SREBPs move from the ER to the Golgi apparatus with the help of SCAP, where the precursor SREBPs are cleaved by site-1 (S1P) and site-2 (S2P) proteases (1,2). Released SREBP amino-terminal domains enter the nucleus and bind to sterol response elements located in the promoters of a number of genes responsible for the cholesterol synthesis (1,2). Research studies show that the SCAP/SREBP pathway is critical for diabetic fatty liver development and carbohydrate-induced hypertriglyceridemia in mice (3). In addition, the SCAP/SREBP pathway is required to protect cancer cells from lipotoxicity (4).
