Abcam's ERK1/2
in vitro
SimpleStep ELISA™ (Enzyme-Linked Immunosorbent Assay) kit is designed for the quantitative measurement of ERK1/2 protein in Human and mouse cells.
The SimpleStep ELISA™ employs an affinity tag labeled capture antibody and a reporter conjugated detector antibody which immunocapture the sample analyte in solution. This entire complex (capture antibody/analyte/detector antibody) is in turn immobilized via immunoaffinity of an anti-tag antibody coating the well. To perform the assay, samples or standards are added to the wells, followed by the antibody mix. After incubation, the wells are washed to remove unbound material. TMB substrate is added and during incubation is catalyzed by HRP, generating blue coloration. This reaction is then stopped by addition of Stop Solution completing any color change from blue to yellow. Signal is generated proportionally to the amount of bound analyte and the intensity is measured at 450 nm. Optionally, instead of the endpoint reading, development of TMB can be recorded kinetically at 600 nm.
As of October 2019, this kit was reformulated with new antibodies to maintain continued long term supply.

ERK1 and ERK2 also known as MAPK3 and MAPK1 respectively are protein kinases involved in the mitogen-activated protein kinase (MAPK) signaling pathway. They share high sequence identity and exhibit similar functions. ERK1 has a molecular weight of approximately 44 kDa while ERK2 weighs around 42 kDa. Both are expressed ubiquitously in various tissues playing roles in diverse cellular processes. These proteins often detected through ERK1/2 western blot analyses present similar ERK protein size and ERK molecular weight characteristics relevant during protein expression studies.
Biological function summary
ERK1 and ERK2 play key roles in cell proliferation differentiation and survival. They form part of a cascade that includes upstream activators such as MEK1/2 and downstream targets including transcription factors. As components of the MAPK signaling complex ERK1/2 regulate gene expression through phosphorylation events impacting cellular responses to various stimuli. Their activation often hinges on growth factors cytokines and stress signals facilitating cellular adaptation to environmental changes.
Pathways
Regarding pathways ERK1/2 sit within the MAPK/ERK pathway and are significant in the Ras/Raf/MEK/ERK cascade one of the foremost signaling mechanisms in cells. They interact with several proteins including Ras and Raf which modulate their activation. This pathway is important for transmitting signals from the cell surface to the DNA in the cell nucleus impacting gene regulation and cell fate decisions. ERK1/2 proteins therefore serve as critical nodes linking extracellular signals to cellular responses ensuring balanced cell function.
ERK1/2 play significant roles in cancer and neurodegenerative diseases. Their overactivation is often linked to oncogenic processes contributing to cell proliferation in cancers. Mutations or dysregulation within the MAPK/ERK pathway including ERK1/2 frequently associate with tumorigenesis. Additionally in neurodegenerative disorders like Alzheimer's disease altered ERK1/2 activity may impact neuronal survival and function often through interaction with amyloid-beta and tau proteins further illustrating their importance in disease pathophysiology.
