Overview:

ASK1, also known as MAPKKK5, activates MKK3, MKK4 (SEK1), and MKK6. Overexpression of ASK1 induces apoptotic cell death, and ASK1 is activated in cells treated with tumor necrosis factor-alpha (1). ASK1 interacts with members of the TRAF family and is activated by TRAF2 in the TNF-signaling pathway. After activation by TRAF2, ASK1 activates MKK4, which in turn activates JNK. Thus, ASK1 is a mediator of TRAF2-induced JNK activation (2).

Specificity:

Recognizes the ASK1 protein

Cross Reactivity:

Human

Host / Isotype / Clone#:

Rabbit, IgG

Immunogen:

ASK1 antibody was raised against a peptide corresponding to amino acids near the carboxy terminus of human ASK1. This sequence is different from that of mouse by last two amino acids.

Purification:

Affinity chromatography

Stability:

Store at 4^oC (add 0.1% NaN₃) for several months, and at -20^oC for longer periods. For optimal storage, aliquot target into smaller quantities after centrifugation and store at recommended temperature. For most favorable performance, avoid repeated handling and multiple freeze/thaw cycles.

Sample Data:

Western blot analysis of ASK1 in SW1353 whole cell lysate with ASK1 antibody at 1:500 dilution.
