MEK1/2 Antibody (YA299)

MEK1/2 Antibody (YA299) is a Rabbit-derived and non-conjugated IgG monoclonal antibody, targeting to MEK1/2.

MEK1 protein, a pivotal component of the MAP kinase signal transduction pathway, plays a crucial role in transducing extracellular signals into intracellular responses. Upon binding of ligands such as growth factors and cytokines to their cell-surface receptors, MEK1 is activated as part of the RAS-RAF1-MEK1/2-MAPK/ERK cascade. MEK1, along with MAP2K2/MEK2, catalyzes the dual phosphorylation of threonine and tyrosine residues in the activation loop of ERK1 and ERK2, thereby initiating downstream signaling events. This cascade regulates diverse biological functions, including cell growth, adhesion, survival, and differentiation. In addition to its role in the transcriptional and cytoskeletal regulation, the MAPK/ERK pathway impacts peroxisome proliferator-activated receptor gamma (PPARG), contributing to cellular processes such as differentiation and apoptosis. Furthermore, MEK1's involvement in endosomal dynamics and Golgi apparatus fragmentation during mitosis underscores its versatility in coordinating intricate cellular responses.

• 
  Western blot analysis of extracts from NIH3T3(lane 2(20μg) , Hela(lane 3(20μg) and HepG2(lane 4(20μg) using MEK1/2(HY-P80218) Rabbit mAb. Proteins were transferred to a PVDF membrane and blocked with 5% non-fat milk in TBST for 2 hour at room temperature. The primary antibody (1/1000) and Loading control antibody (Beta Actin, HY-P80438, 1/10000) was used in 5% non-fat milk in TBST at 4°C overnight. Goat Anti-Mouse/Rabbit IgG-HRP Secondary Antibody (1/10000) was used for 1 hour at room temperature.
• 
  Immunocytochemistry analysis of NIH3T3 cells labeling MEK1/2 with MEK1/2 Antibody (HY-P80218) at 1/50 dilution. Cells were fixed in 4% paraformaldehyde for 15 minutes at room temperature, permeabilized with 0.1% Triton X-100 for 10 minutes at room temperature, then blocked with QuickBlock™ Blocking Buffer for Immunol Staining for 10 min at room temperature. Cells were then incubated with MEK1/2 Antibody (HY-P80218)at 1/50 dilution in QuickBlock™ Blocking Buffer for Immunol Stainingat 4 ℃. Alexa Fluor® 488-conjugated AffiniPure Goat Anti-Rabbit IgG H&L（HY-P8002, Green) was used as the secondary antibody at 1/1,000 dilution. PBS instead of the primary antibody was used as the secondary antibody only control. The Nuclear counterstain was DAPI (Blue).

• 
  Immunohistochemical analysis of paraffin-embedded Mouse lung tissue using MEK1/2 Antibody. The section was pre-treated using heat mediated antigen retrieval with Tris-EDTA buffer (pH 8.0) for 8 minutes. The tissues were blocked in QuickBlock for 20 minutes at room temperature, washed with ddH2O and PBS, and then probed with the primary antibody (HY-P80218, 1:200) in 4℃ overnight. The detection was performed using an HRP conjugated compact polymer system. DAB was used as the chromogen. Tissues were counterstained with hematoxylin and mounted with DPX.
