Full Methods

Primary Antibody:

• Antigen: Growth Factor Receptor-Bound Protein 2 (GRB2) (1:200 dilution)
• Catalog number: ABIN686932
• Lot number: 121228

Secondary Antibody:

• Antigen: Goat Anti-Rabbit IgG (H + L)-HRP Conjugate (1:20,000 dilution)
• Lot number: L170-6515

Full Protocol:

• Total protein extracts were boiled in 1X SDS Sample Buffer containing 1% SDS and 1.25% β-mercaptoethanol at 95°C for 5 min prior to loading.
• 46 μg of boiled extracts were loaded and resolved on a 8-16% SDS-polyacrylamide gel.
• The Spectra Multicolor Broad Range (Thermo Scientific, Cat # 26634) were used as molecular mass markers.
• Proteins were transferred onto PVDF membrane by wet transfer and protein transfer was confirmed with Ponceau-S staining.
• The PVDF membrane was incubated with 25 mL of blocking buffer [Tris Buffered Saline, pH 7.4 plus 0.1% TW20 (TBST)] containing 5% (W/V) non-fat dry milk at room temperature for 1 h.
• The membrane was rinsed with TBST once.
• The membrane was immersed with the protein side up in the primary antibody solution (anti-GRB2; 1:200) in TBST containing 5% (W/V) non-fat dry milk and incubated for 16 hours at 4°C.
• The membrane was rinsed in TBST three times for 5 min each.
• The membrane was incubated in the HRP-conjugated secondary antibody solution (goat-anti rabbit IgG-HRP; 1:20,000) in TBST containing 5% (W/V) non-fat dry milk and incubated for 1 hour at room temperature (~26°C) with gentle agitation.
• The membrane was rinsed three times with TBST for 5 min each.
• The membrane was rinsed in TBS twice for 30 s each.
• Signals were detected with ECL-2 Substrate. The blot was scanned for 300 s.
• The membrane was rinsed three times with TBST, then incubated in Acidic Glycine Stripping Buffer at room temperature with gentle agitation for 3 times, 10 min each.
• The membrane was washed in TBST 2 times for 10 min each.
• Repeated Steps 5-12 with the loading control antibody (anti-Actin; 1:6,000) and its matching secondary antibody (goat-anti rabbit IgG-HRP; 1:20,000).

Experimental Notes: Nothing to note.
