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.

    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.
