Catalog No. ABIN116930

The Rabbit Polyclonal anti-ASK1 antibody has been validated for WB. It is suitable to detect ASK1 in samples from Human.

Quick Overview for ASK1 antibody (pSer83) (ABIN116930)

Target: ASK1 (MAP3K5) (Mitogen-Activated Protein Kinase Kinase Kinase 5 (MAP3K5))

Reactivity: Human

Host: Rabbit

Clonality: Polyclonal

Conjugate: This ASK1 antibody is un-conjugated

Application: Western Blotting (WB)

Product Details anti-ASK1 Antibody

Binding Specificity: AA 76-87, pSer83

Specificity: 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.

Purification: Multi-step process.

Immunogen: This purified antibody was prepared from rabbit serum after repeated immunizations with a KLH conjugated peptide corresponding to amino acids 76-87 of human ASK-1 protein.

Application Details

Application Notes: This phospho specific polyclonal antibody reacts human pS83 ASK1 and shows minimalreactivity by Western blot, ELISA and competitive ELISA with non-phosphorylated ASK1. Although not tested, this antibody is likely functional in RIA, Immunohistochemistry andImmunoprecipitation. Recommended Dilutions: 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 canbe used as a positive control. For ELISA a 1/5,000-1/10,000 dilution is recommended.
Other applications not tested.
Optimal dilutions are dependent on conditions and should be determined by the user.

Target Details for ASK1

Target: ASK1 (MAP3K5) (Mitogen-Activated Protein Kinase Kinase Kinase 5 (MAP3K5))

Alternative Name: MEKK5 / ASK1

Background: 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).
