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.

Phospho-CK2 Substrate [(pS/pT)DXE] MultiMab™ Rabbit mAb mix recognizes endogenous proteins containing a pS/pTDXE motif, which is a CK2 phosphorylation consensus sequence. This antibody is a useful tool to study CK2 substrates.Species Reactivity:
All Species Expected
MultiMab™ rabbit monoclonal mix antibodies are prepared by combining individual rabbit monoclonal clones in optimized ratios for the approved applications. Each antibody in the mix is carefully selected based on motif recognition and performance in multiple assays. Each mix is engineered to yield the broadest possible coverage of the modification being studied while ensuring a high degree of specificity for the modification or motif.
Casein Kinase II (CK2) is a highly conserved, ubiquitously expressed, and constitutively active tetrameric Ser/Thr protein kinase with hundreds of substrates participating in the regulation of a variety of cellular processes including cell cycle progression, apoptosis, transcription, inflammation, and the DNA damage response. Research studies have implicated CK2 in roles related to viral infection, cancer, and other diseases (1-5). CK2 substrates contain multiple acidic residues (Asp and Glu) located downstream of the phosphorylated Ser or Thr residue. The consensus sequence for CK2 substrates is pS/pTD/EXD/E with the most crucial residue at the +3 position followed by the residue at the +1 position (6).
