General notes
ab281892 is the carrier-free version of ab281846.
This antibody clone is manufactured by Abcam. If you require a custom buffer formulation or conjugation for your experiments, please contact orders@abcam.com.
Our carrier-free antibodies are typically supplied in a PBS-only formulation, purified and free of BSA, sodium azide and glycerol. The carrier-free buffer and high concentration allow for increased conjugation efficiency.
This conjugation-ready format is designed for use with fluorochromes, metal isotopes, oligonucleotides, and enzymes, which makes them ideal for antibody labelling, functional and cell-based assays, flow-based assays (e.g. mass cytometry) and Multiplex Imaging applications.
Use our conjugation kits for antibody conjugates that are ready-to-use in as little as 20 minutes with <1 minute hands-on-time and 100% antibody recovery: available for fluorescent dyes, HRP, biotin and gold.
This product is compatible with the Maxpar® Antibody Labeling Kit from Fluidigm, without the need for antibody preparation. Maxpar® is a trademark of Fluidigm Canada Inc.
This product is a recombinant monoclonal antibody, which offers several advantages including:
- - High batch-to-batch consistency and reproducibility
- - Improved sensitivity and specificity
- - Long-term security of supply
- - Animal-free production

Function
Adapter 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 similarities
Belongs to the GRB2/sem-5/DRK family.
Contains 1 SH2 domain.
Contains 2 SH3 domains. -
Domain
The SH3 domains mediate interaction with RALGPS1 and SHB. -
Cellular localization
Golgi apparatus. - Information by UniProt

Observed band size: 26 kDa why is the actual band size different from the predicted?This data was developed using ab281846, the same antibody clone in a different buffer formulation.
Blocking and diluting buffer and concentration: Intercept® (TBS) Blocking Buffer diluted with an equal volume of 0.1% TBS
Lanes 1-4: Merged signal (red and green). Green - ab281846 observed at 26KDa. Red - loading control ab181602 (Rabbit monoclonal [EPR16891] to GAPDH) observed at 36 kDa.
Lanes 1-2: ab281846 Anti-GRB2 antibody was shown to react with GRB2 in HCT116 cells in Western blot. Loss of signal was observed when GRB2 knockout cell line ab273715 (knockout cell lysate ab275248) was used. Wild-type and GRB2 knockout samples were subjected to SDS-PAGE.
ab281846 and Anti-GAPDH antibody [EPR16891] - Loading Control (ab181602) were incubated at 4? overnight at 1 in 1000 dilution and 1 in 20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 680CW) preadsorbed (ab216777) and Goat anti-Mouse IgG H&L (IRDye® 800RD) preadsorbed (ab216772) secondary antibodies at 1 in 10000 dilution for 1 hour at room temperature before imaging. -
