Western blot analysis of extracts from THP-1 cells, differentiated with TPA (12-O-Tetradecanoylphorbol-13-Acetate) #4174 (80 nM, 16 hr) and then left untransfected (-) or transfected with poly(dA:dT) (5 μg/ml, 16 hr; +), using IFN-β1 (D1D7G) Rabbit mAb (upper) or β-Actin (D6A8) Rabbit mAb #8457 (lower). Brefeldin A #9972 (300 ng/ml) was added to cells 4 hr after the start of the transfection.Learn more about how we get our images.

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.

IFN-β1 (D1D7G) Rabbit mAb recognizes endogenous levels of total IFN-β1 protein.
Monoclonal antibody is produced by immunizing animals with recombinant human IFN-β1 protein.
The type I interferon (IFN) family includes IFN-β1 and IFN-α1 through IFN-α13 in humans and IFN-α1 through IFN-α14 in mice. Type I IFN is produced following detection of pathogen-associated molecular patterns (PAMPs) and is important for induction of antiviral genes, activation of dendritic cells, and initiation of adaptive immunity (1, 2). Type I IFNs signal through the IFN alpha receptor (IFNAR), which is a heterodimer composed of IFNAR1 and IFNAR2. Activation of IFNAR leads to formation of the nuclear complex IFN-stimulated gene factor 3 (ISGF3), which consists of STAT1, STAT2, and IRF-9 (3, 4). ISGF3 binds to IFN-stimulated response elements (ISREs) to initiate transcription of interferon-stimulated genes (3).
