Background Information

EIF2A, also named as CDA02, MSTP004 and MSTP089, belongs to the WD repeat EIF2A family. It functions in the early steps of protein synthesis of a small number of specific mRNAs. EIF2A, an alternative initiator tRNA-binding protein, has a key role in the translation of HCV mRNA during HCV infection, in turn promoting eIF2a phosphorylation by activating the eIF2a kinase PKR. This antibody is a rabbit polyclonal antibody raised against residues near the C terminus of human EIF2A, recognizes specifically the 65kd EIF2A protein.

Daniel (Verified Customer) (04-01-2019)

The provided antibody exceeded all expectations. It worked very well on the first try.Mouse liver was homogenized in Final sample buffer, and then proteins were separated by 10% SDS-PAGE followed by western blot with 11233-1-AP(EIF2A antibody) at a dilution of 1:1000 incubated at 4 degrees Celsius over night in 5% BSA TBST.

  • Applications: Western Blot,
  • Primary Antibody Dilution: 1:1000
  • Cell Tissue Type: Mouse Liver
