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.
MST4 Antibody recognizes endogenous levels of total MST4 protein independent of phosphorylation. The antibody does not cross-react with MST1-3 proteins.
Human, Mouse, Rat, Monkey, Bovine
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to the amino-terminal residues of human MST4 protein. Antibodies are purified by protein A and peptide affinity chromatography.
Mammalian sterile-20-like (MST) kinases are upstream regulators of mitogen-activated protein kinase (MAPK) signaling pathways that regulate multiple biological processes, including apoptosis, morphogenesis, cell migration, and cytoskeletal rearrangements (1). This group of serine/threonine kinases includes a pair of closely related proteins (MST1, MST2) that are functionally distinct from the more distantly related MST3 and MST4 kinases. All four MST kinases share a conserved amino-terminal kinase domain and carboxy-terminal regulatory and interaction domains (1-3). At least three of these kinases (MST1-3) promote apoptosis and are activated by caspase cleavage followed by nuclear translocation of the active kinase. MST1/2 kinases play a key role in the Hippo signaling pathway, an evolutionarily conserved program that controls organ size by regulating cell proliferation, apoptosis, and stem cell self renewal (4).
Mammalian Sterile 20-like kinase 4 (MST4, STK26, MASK) is a Golgi-localized kinase that is cleaved by caspase-3 in vitro. While its potential role in apoptosis is unclear, research studies indicate that MST4 is involved in MAPK and EGF pathway signaling (5,6). MST4 and the serine/threonine kinase YSK1 (STK25) localize to the Golgi apparatus following association with the Golgi scaffold protein GM130. Binding to GM130 activates MST4 through autophosphorylation at Thr178 (7).
