Western blot analysis of extracts from untreated or anisomycin-treated C6 cells, or untreated or UV-treated 293 cells, using Phospho-c-Jun (Ser63) (54B3) Rabbit mAb #2361 (upper) or c-Jun (60A8) Rabbit mAb #9165 (lower).
Western blot analysis of extracts from various cell lines, untreated or treated with sorbitol or UV, as indicated, using Phospho-SEK1/MKK4 (Ser257) (C36C11) Rabbit mAb #4514.
Western blot analysis of extracts from 293 cells, untreated or UV-treated, NIH/3T3 cells, untreated or UV-treated and C6 cells, untreated or anisomycin-treated, using Phospho-SAPK/JNK (Thr183/Tyr185) (81E11) Rabbit mAb #4668.
The Phospho-SAPK/JNK Pathway Antibody Sampler Kit provides a fast and economical means of evaluating multiple members of the SAPK/JNK pathway as well as their activation state. The kit contains enough primary and secondary antibodies to perform four Western blot experiments.
Specificity / Sensitivity
Each antibody in the Phospho-SAPK/JNK Antibody Sampler Kit recognizes endogenous levels of the phosphorylated form of its specific target.
Source / Purification
Monoclonal antibodies are produced by immunizing animals with a synthetic phosphopeptides corresponding to residues surrounding Ser257 of human SEK1, Thr183/Tyr185 of human SAPK, Thr71 of human ATF-2 or Ser63 of human c-Jun.
The stress-activated protein kinase/Jun-amino-terminal kinase SAPK/JNK is potently and preferentially activated by a variety of environmental stresses including UV and gamma radiation, ceramides, inflammatory cytokines, and in some instances, growth factors and GPCR agonists (1-6). As with the other MAPKs, the core signaling unit is composed of a MAPKKK, typically MEKK1-MEKK4, or by one of the mixed lineage kinases (MLKs), which phosphorylate and activate MKK4/7. Upon activation, MKKs phosphorylate and activate the SAPK/JNK kinase (2). Stress signals are delivered to this cascade by small GTPases of the Rho family (Rac, Rho, cdc42) (3). Both Rac1 and cdc42 mediate the stimulation of MEKKs and MLKs (3). Alternatively, MKK4/7 can be activated in a GTPase-independent mechanism via stimulation of a germinal center kinase (GCK) family member (4). There are three SAPK/JNK genes each of which undergoes alternative splicing, resulting in numerous isoforms (3). SAPK/JNK, when active as a dimer, can translocate to the nucleus and regulate transcription through its effects on c-Jun, ATF-2, and other transcription factors (3,5).
