Human ERK1 Antibody Summary

Species Reactivity
Human
Specificity
Detects human ERK1 in Western blots. Because the peptide immunogen corresponds to a region of ERK1 largely absent in ERK2, no reactivity with ERK2 is present.
Source
Polyclonal Rabbit IgG
Purification
Antigen Affinity-purified
Immunogen
Human ERK1 synthetic peptide
Met1-Val28
Accession # P27361
Formulation
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied as a 0.2 µm filtered solution in PBS.
Label
Unconjugated

Applications

Data Example

Western Blot Detection of Human ERK1 by Western Blot. View Larger

Detection of Human ERK1 by Western Blot. Western blot shows lysates of MCF-7 human breast cancer cell line, HepG2 human hepatocellular carcinoma cell line, Jurkat human acute T cell leukemia cell line, and DU145 human prostate carcinoma cell line. PVDF membrane was probed with 0.1 µg/mL Rabbit Anti-Human ERK1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1940) followed by HRP-conjugated Anti-Rabbit IgG Secondary Antibody (Catalog # HAF008). For additional reference, Rec­ombinant Human Active ERK1 (Catalog # 1879-KS) and Recom­binant Human Active ERK2 (Catalog # 1230-KS) (2 ng/lane) were included. A specific band for ERK1 was detected at approximately 42 kDa (as in­dicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 1.

Background: ERK1

ERK1 is a protein Serine/Threonine kinase that is a member of the extracellular signal-regulated kinases (ERKs) which are activated in response to numerous growth factors and cytokines (1). Activation of ERK1 requires both tyrosine and threonine phosphorylation that is mediated by MEK. ERK1 is ubiquitously distributed in tissues with the highest expression in heart, brain, and spinal cord. Activated ERK1 translocates into the nucleus where it phosphorylates various transcription factors.
