ASK-1 (apoptosis signal-regulating kinase 1 - also referred to as MEK Kinase-5 or MAPKKK5) is a novel serine/threonine MAP kinase kinase kinase (MAPKKK) component of the mitogen -activated protein (MAP) cascade that is activated in response to extracellular stimuli by cytokines, growth factors and environmental stresses and other factors.   Overexpression of ASK-1 induces apoptotic cell death.  ASK-1 is expressed in a variety of human and mouse tissues.  The overall amino acid sequence identity between the mouse and human ASK1 is 91.9%.  ASK-1 interacts with CDKN1A (also known as p21, WAF1, CIP1).  Please refer to the reference list at the end of this document for further information.

Conjugated Peptide
This purified antibody was prepared from rabbit serum after repeated immunizations with a KLH conjugated peptide corresponding to an internal region near amino acids 75-100 of human ASK-1 protein.
This product is an IgG fraction antibody purified from antiserum by a multi-step process which includes delipidation, salt fractionation and ion exchange chromatography followed by extensive dialysis against the buffer stated above. Assay by immunoelectrophoresis resulted in a single precipitin arc against anti-Rabbit Serum. No reaction was observed with ASK-1 from mouse sources. Reactivity with the kinase from other sources has not been determined.

Application Details

IHC, IP  - View References
This phospho specific polyclonal antibody reacts human pS83 ASK1 and shows minimal reactivity by western blot, ELISA and competitive ELISA with non-phosphorylated ASK1. Although not tested, this antibody is likely functional in RIA, immunohistochemistry and immunoprecipitation. For immunoblotting a 1:1,000 dilution is recommended.  A 155 kDa band corresponding to human ASK-1 is detected.  Whole cell lysates from SW1353 can be used as a positive control.  For ELISA a 1:5,000 to 1:10,000 dilution is recommended.   Researchers should determine optimal titers for other applications.
