Product Description

The MAPK Family Antibody Sampler Kit provides an economical means of evaluating total levels of p38, p44/42, and SAPK/JNK mitogen-activated protein kinases. The kit contains enough primary and secondary antibody to perform two western blot experiments.

Specificity / Sensitivity

Each antibody in the MAPK Family Antibody Sampler Kit recognizes only its specific target. The antibodies do not cross-react with other MAP kinases.

Source / Purification

p44/42 MAP Kinase (137F5) Rabbit mAb is produced by immunizing animals with a synthetic peptide corresponding to residues near the C-terminus of rat p44 MAP kinase. p38 MAPK (D13E1) XP® Rabbit mAb is produced by immunizing animals with a synthetic peptide corresponding to the carboxy terminus of human p38 protein. SAPK/JNK Antibody is produced by immunizing animals with a recombinant human JNK2 fusion protein. Polyclonal antibodies are purified by protein A and peptide affinity chromatography.

Background

p44/42 MAPK (Erk1/2), SAPK/JNK, and p38 MAPK function in protein kinase cascades that play a critical role in the regulation of cell growth, differentiation, and control of cellular responses to cytokines and stress. p44/42 MAPK is activated by growth and neurotrophic factors. Activation occurs through phosphorylation of threonine and tyrosine residues (Thr202 and Tyr204 in human Erk1) at the sequence T*EY* by a single upstream MAP kinase kinase (MEK). SAPK/JNK and p38 MAPK are activated by inflammatory cytokines and by a wide variety of cellular stresses. Activation of SAPK/JNK occurs via phosphorylation at Thr183 and Tyr185 by the dual specificity enzyme SEK/MKK4. Both MKK3 and SEK phosphorylate p38 MAPK on tyrosine and threonine at the sequence T*GY* to activate p38 MAP kinase (1-5).
