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.

DUSP10/MKP5 Antibody detects endogenous levels of total DUSP10 protein.Species Reactivity:
Human, Mouse, Rat
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to human DUSP10. Antibodies are purified by protein A and peptide affinity chromatography.
MAP kinases are inactivated by dual-specificity protein phosphatases (DUSPs) that differ in their substrate specificity, tissue distribution, inducibility by extracellular stimuli, and cellular localization. DUSPs, also known as MAPK phosphatases (MKP), specifically dephosphorylate both threonine and tyrosine residues in MAPK P-loops and have been shown to play important roles in regulating the function of the MAPK family (1,2). At least 13 members of the family (DUSP1-10, DUSP14, DUSP16, and DUSP22) display unique substrate specificities for various MAP kinases (3). MAPK phosphatases typically contain an amino-terminal rhodanese-fold responsible for DUSP docking to MAPK family members and a carboxy-terminal catalytic domain (4). These phosphatases can play important roles in development, immune system function, stress responses, and metabolic homeostasis (5). In addition, research studies have implicated DUSPs in the development of cancer and the response of cancer cells to chemotherapy (6).
DUSP10, or MKP5, selectively phosphorylates and inactivates p38α MAP kinase and JNK, but does not appear to affect p44/42 MAPK. Activated JNK phosphorylates the ATF2 transcription factor during periods of oxidative stress, which induces expression of DUSP10 and related phosphatases. Increased DUSP10 activity helps to further coordinate JNK activity during the stress response (7). Studies using DUSP10 deficient mice demonstrated a likely role of this phosphatase in both the adaptive and innate immune responses (8).
