Application	Abreviews	Notes
WB		1/1000 - 1/2000. Predicted molecular weight: 25 kDa.
IHC-P		Use at an assay dependent concentration.
ICC/IF		1/100 - 1/250.
Flow Cyt		1/40. ab172730 - Rabbit monoclonal IgG, is suitable for use as an isotype control with this antibody.

Application notes

Is unsuitable for IP.

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.

Flow Cytometry - Anti-GRB2 antibody [Y301] (ab32111)

Overlay histogram showing SH-SY5Y cells stained with ab32111 (red line). The cells were fixed with 4% paraformaldehyde (10 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab32111, 1/100 dilution) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-rabbit IgG (H+L) (ab96899) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was rabbit IgG (monoclonal) (1µg/1x10⁶ cells) used under the same conditions. Acquisition of >5,000 events was performed.

Question

What is the recommended antigen retrieval buffer for these three antibodies?

Asked on Jan 23 2012

Answer

Thank you for contacting us.

The following standard heat-mediated citrate buffer antigen retrieval was used for the IHC validation of ab32111 and ab111031. Antibody ab111586 used citrate buffer in a pressure cooker at 120C for 5 minutes but a steamer or waterbath at 95-100C will be an acceptable substitute.

Place slides in a container of 0.01 M sodium citrate buffer, pH 6.0 heated to 100°C and maintain this temperature for 20 minutes by placing the container in a steamer or heated waterbath. After 20 minutes, remove from heat and let stand at room temperature in buffer for 20 minutes. Rinse in 1X TBS with Tween (TBST) for 1 minute at RT.

I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.
