ELISA Image 1: PathScan® Total p44/42 MAPK (Erk1/2) Sandwich ELISA Kit
Figure 1. Treatment of NIH/3T3 cells with PDGF stimulates phosphorylation of p44/42 MAPK at Thr202/Tyr204, detected by the PathScan® Phospho-p44/42 MAPK (Thr202/Tyr204) Sandwich ELISA Kit #7177, but has little effect on the total level of p44/42 MAPK detected by PathScan® Total p44/42 MAPK (Erk1/2) Sandwich ELISA Kit. NIH/3T3 cells (80-90% confluent) were starved overnight and treated with 100 ng/mL PDGF for 5 minutes at 37ºC. The absorbance readings at 450 nm are shown in the top figure, while the corresponding western blots, using p44/42 MAPK (Erk1/2) Antibody #9102 (left panel) and Phospho-p44/42 MAPK (Erk1/2) (Thr202/Tyr204) (D13.14.4E) XP® Rabbit mAb #4370 (right panel), are shown in the bottom figure.

Product Information

Product Description

The PathScan® Total p44/42 MAPK (Erk1/2) Sandwich ELISA Kit is a solid phase sandwich enzyme-linked immunosorbent assay (ELISA) that detects endogenous levels of p44/42 MAPK (Erk1/2). A p44/42 MAPK mouse mAb has been coated onto the microwells. After incubation with cell lysates, p44/42 MAPK is captured by the coated antibody. Following extensive washing, a p44/42 MAPK rabbit detection mAb is added to detect the captured p44/42 MAPK protein. Anti-Rabbit IgG, HRP-linked antibody is then used to recognize the bound detection antibody. HRP substrate, TMB, is added to develop color. The magnitude of absorbance for this developed color is proportional to the quantity of total p44/42 MAPK.

*Antibodies in this kit are custom formulations specific to kit.

Protocol

Specificity / Sensitivity

CST's PathScan® Total p44/42 MAPK (Erk1/2) Sandwich ELISA Kit #7050 detects endogenous levels of total p44/42 MAPK protein (see Figure 1). The kit sensitivity is shown in Figure 2. This kit detects proteins from the indicated species, as determined through in-house testing, but may also detect homologous proteins from other species.

Species Reactivity:

Human, Mouse

Background

Mitogen-activated protein kinases (MAPKs) are a widely conserved family of serine/threonine protein kinases involved in many cellular programs, such as cell proliferation, differentiation, motility, and death. The p44/42 MAPK (Erk1/2) signaling pathway can be activated in response to a diverse range of extracellular stimuli, including mitogens, growth factors, and cytokines (1-3), and research investigators consider it an important target in the diagnosis and treatment of cancer (4). Upon stimulation, a sequential three-part protein kinase cascade is initiated, consisting of a MAP kinase kinase kinase (MAPKKK or MAP3K), a MAP kinase kinase (MAPKK or MAP2K), and a MAP kinase (MAPK). Multiple p44/42 MAP3Ks have been identified, including members of the Raf family, as well as Mos and Tpl2/COT. MEK1 and MEK2 are the primary MAPKKs in this pathway (5,6). MEK1 and MEK2 activate p44 and p42 through phosphorylation of activation loop residues Thr202/Tyr204 and Thr185/Tyr187, respectively. Several downstream targets of p44/42 have been identified, including p90RSK (7) and the transcription factor Elk-1 (8,9). p44/42 are negatively regulated by a family of dual-specificity (Thr/Tyr) MAPK phosphatases, known as DUSPs or MKPs (10), along with MEK inhibitors, such as U0126 and PD98059.
