  • Application notes
    Is unsuitable for Flow Cyt or IP.
  • Target

    • Function
      Functions in the early steps of protein synthesis of a small number of specific mRNAs. Acts by directing the binding of methionyl-tRNAi to 40S ribosomal subunits. In contrast to the eIF-2 complex, it binds methionyl-tRNAi to 40 S subunits in a codon-dependent manner, whereas the eIF-2 complex binds methionyl-tRNAi to 40 S subunits in a GTP-dependent manner. May act by impiging the expression of specific proteins.
    • Tissue specificity
      Widely expressed. Expressed at higher level in pancreas, heart, brain and placenta.
    • Sequence similarities
      Belongs to the WD repeat EIF2A family.
      Contains 3 WD repeats.

    • Lane 1: Wild-type HAP1 cell lysate (20 µg)
      Lane 2: eIF2A knockout HAP1 cell lysate (20 µg)
      Lane 3: Ramos cell lysate (20 µg)
      Lane 4: MOLT4 cell lysate (20 µg)
      Lanes 1 - 4: Merged signal (red and green). Green - ab169528 observed at 65 kDa. Red - loading control, ab8245, observed at 37 kDa.

      ab169528 was shown to specifically react with eIF2A when eIF2A knockout samples were used. Wild-type and eIF2A knockout samples were subjected to SDS-PAGE. ab169528 and ab8245 (loading control to GAPDH) were diluted at 1/1000 and 1/10 000 respectively and incubated overnight at 4°C. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preadsorbed (ab216773) and Goat anti-Mouse IgG H&L (IRDye® 680RD) preadsorbed (ab216776) secondary antibodies at 1/10 000 dilution for 1 h at room temperature before imaging.

    • Immunocytochemistry/Immunofluorescence analysis of HeLa (Human epithelial cell line from cervix adenocarcinoma) labeling eIF2A with purified ab169528 at 1/250 dilution. Cells were fixed with 4% PFA and permeabilized with 0.1% tritonX-100. ab150077 Goat anti rabbit IgG (Alexa Fluor®488) at 1/1000 was used as the secondary antibody. Nuclei were counterstained with DAPI. PBS was used instead of the primary antibody as the negative control.
