Our Abpromise guarantee covers the use of ab59362 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
ICC/IF Use a concentration of 1 - 5 µg/ml.
WB 1/500 - 1/1000. Detects a band of approximately 77 kDa.
IHC-P Use at an assay dependent concentration.
ELISA 1/10000.


  • Function
    Probably involved in EGF and insulin receptor signaling.
  • Sequence similarities
    Belongs to the GAB family.
    Contains 1 PH domain.
  • Post-translational
    Phosphorylated on tyrosine residue(s) by the epidermal growth factor receptor (EGFR) and the insulin receptor (INSR). Tyrosine phosphorylation of GAB1 mediates interaction with several proteins that contain SH2 domains.

  • All lanes : Anti-GAB1 antibody (ab59362) at 1/500 dilution

    Lane 1 : Extracts from NIH/3T3 cells with no immunizing peptide
    Lane 2 : Extracts from NIH/3T3 cells with immunizing peptide

    Observed band size: 77 kDa (why is the actual band size different from the predicted?)

  • ab59362, at a 1/50 dilution, staining human GAB1 in breast carcinoma, using Immunohistochemistry, Paraffin embedded tissue, in the absence of the immunizing peptide (left image) and in the presence of the immunizing peptide (right image).
  • ICC/IF image of ab59362 stained HeLa cells. The cells were 100% methanol fixed (5 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab59362, 1µg/ml) overnight at +4°C. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
