Anti Phosphorylated ASK1 / Anti ASK1
Mitogen-activated protein (MAP) kinase cascades are activated in response to various extracellular stimuli,
including growth factors and environmental stresses. A MAP kinase kinase kinase (MAPKKK), termed ASK1, was
identified that activated two different subgroups of MAP kinase kinases (MAPKK), SEK1 (or MKK4) and
MKK3/MAPKK6 (or MKK6), which in turn activated stress-activated protein kinase (SAPK, also known as JNK;
c-Jun amino-terminal kinase) and p38 subgroup of MAP kinases, respectively. Overexpression of ASK1 induced
apoptotic cell death, and ASK1 was activated in cells treated with tumor necrosis factor-alpha (TNF-alpha).
Moreover, TNF-alpha-induced apoptosis was inhibited by a catalytically inactive form of ASK1. ASK1 may be a
key element in the mechanism of stress- and cytokine-induced apoptosis.
■ Anti Phosphorylated ASK1,
Monoclonal Antibody (Wako Cat. No.
017-22351 (50 µg))
Reacts with human ASK1
including phosphorylated mouse Thr838 and human Thr845.
Cross-reacts to ASK2 and ASK3, which phosphorylated site are the same as that of ASK1.
No cross-reaction with human ASK1 Thr838
Clone No.: PA214
1 : 1,000
Specificity of Anti Phosphorylated
ASK1 tagged with Flag was transfected into HEK293A cells and Western blot analysis was performed using
anti-phosphorylated ASK1 antibody (PA214). As a result, the band could be detected only in the Stim lane
ASK1 overexpressing cells stimulated with H2O2 for phosphorylation. (Data were
provided by Dr. Maruyama, J. and

||Wild type human ASK1 was overexpressed and
H2O2 stimulation was conducted for activation.
■ Anti ASK1,
Monoclonal Antibody (Wako Cat. No. 010-22341 (50 µg))
Reacts with human and mouse ASK1
No cross-reactive with ASK2.
Clone No.: TC003
Specificity of Anti ASK1 (TC003)
Bone marrow-derived macrophages were extracted from ASK1 (+/+) and ASK1 (-/-) mice and Western blot analysis
was performed using ASK1 antibody (TC003). As a result, samples derived only from ASK1 (+/+) mice could be
detected. (Data were provided by Dr. Maruyama, J. and Noguchi, T., Cell Signaling, Graduate School of
Pharmaceutical Sciences, the University of Tokyo)
