Background Information

ERK1 and ERK2 belongs to the protein kinase superfamily. It is involved in both the initiation and regulation of meiosis, mitosis, and postmitotic functions in differentiated cells by phosphorylating a number of transcription factors such as ELK-1. ERK1/2 catalized the reaction: ATP + a protein = ADP + a phosphoprotein. It is activated by tyrosine phosphorylation in response to INS and NGF. This antibody can recognize both ERK1 and ERK2 with the molecular mass of 38-44 kDa.

good results on human lysates

  • Applications: Western Blot
  • Primary Antibody Dilution: 1:1000

Tom (Verified Customer) (09-29-2020)

10ug of HEK293T total cell lysate in SDS loading buffer was loaded and ran on a 4-20% gradient gel. Blocking was performed in 5% BSA in TBS for 1 hour then membrane incubated at 4 degrees overnight with anti-ERK 1/2 antibody (1:1000) in block. A goat anti-rabbit HRP secondary antibody (1:10,000) was used.

  • Applications: Western Blot
  • Primary Antibody Dilution: 1:1000
  • Cell Tissue Type: HEK293T
