ab199376 - Rabbit monoclonal IgG (Low endotoxin, Azide free), is suitable for use as an isotype control with this antibody.
|IHC-P||Use at an assay dependent concentration. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.|
FunctionAdapter protein that provides a critical link between cell surface growth factor receptors and the Ras signaling pathway.
Isoform GRB3-3 does not bind to phosphorylated epidermal growth factor receptor (EGFR) but inhibits EGF-induced transactivation of a RAS-responsive element. Isoform GRB3-3 acts as a dominant negative protein over GRB2 and by suppressing proliferative signals, may trigger active programmed cell death.
Sequence similaritiesBelongs to the GRB2/sem-5/DRK family.
Contains 1 SH2 domain.
Contains 2 SH3 domains.
DomainThe SH3 domains mediate interaction with RALGPS1 and SHB.
Cellular localizationGolgi apparatus.

Flow cytometry analysis of HeLa (Human cervix adenocarcinoma epithelial cell) cells labeling GRB2 (red) with ab32037 at a 1/20 dilution. Cells were fixed with 4% paraformaldehyde and permeabilized with 90% methanol. A goat anti-rabbit IgG (Alexa Fluor® 488) (ab150077) was used as the secondary antibody at a 1/2000 dilution. Black - Rabbit monoclonal IgG (Black) (ab172730). Blue (unlabeled control) - Cell without incubation with primary antibody and secondary antibody (Blue).
This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab32037).
This IHC data was generated using the same anti-GRB2 antibody clone, Y237, in a different buffer formulation (cat# ab32037).
Immunohistochemical analysis of GRB2 expression in paraffin embedded human ovarian carcinoma, using 1/100 ab32037.
Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.
